{"title":"GMC, (2001-2004), LB7","description":"\u003cdiv class=\"sds-copy-intro\"\u003e\u003cp\u003eParts for the 2001-2004 GMC Sierra 2500HD and Sierra 3500 with the 6.6L LB7 Duramax. These were the first Sierra heavy-duty trucks to leave the plant with a Duramax and an Allison behind it. Two decades on, the cooling stack, the steering linkage and the suction-side fuel system are what decide whether one keeps working.\u003c\/p\u003e\u003c\/div\u003e\u003cdiv class=\"sds-copy-guide\"\u003e\n\u003ch2\u003eThe LB7 Duramax in the 2001-2004 Sierra 2500HD and 3500\u003c\/h2\u003e\n\u003cp\u003eGMC launched the GMT800 heavy-duty Sierra for 2001 in SL, SLE and SLT trim; there was no Denali on an HD pickup in these years. The engine was new too: the 6.6L \u003ca href=\"\/collections\/duramax\"\u003eDuramax\u003c\/a\u003e LB7, built by DMAX Ltd., the GM and Isuzu joint venture in Moraine, Ohio, with engine production starting in July 2000. It replaced the 6.5L Detroit diesel in the old GMT400 trucks. The LB7 is a 90-degree pushrod V8 with a deep-skirt cast-iron block, induction-hardened bores, aluminum four-valve heads, a forged crank and forged rods, and 17.5:1 compression, rated 300 hp at 3,100 rpm and 520 lb-ft at 1,800 rpm. Behind it sat either the Allison 1000 five-speed automatic (RPO M74) or the ZF S6-650 six-speed manual (RPO ML6), both held to 520 lb-ft of input torque. Almost everything interesting lives in the engine valley: the gear-driven Bosch CP3 at the front, the IHI RHG6 fixed-geometry wastegated turbo at the rear, which is the only Duramax turbo without variable vanes, and eight solenoid injectors tucked under the valve covers in brass cups along with their high-pressure lines and harness. There is no electric lift pump, so the CP3 pulls fuel out of a 26-gallon tank by suction through the frame-mounted filter head. Underneath, a full-floating AAM 11.5-inch rear axle with 3.73 or 4.10 gears carries the load, and four-wheel-drive Sierras use an AAM 9.25-inch independent front differential. On emissions hardware the LB7 is simple: 2001 trucks and 2002-2004 federal trucks (RPO FE9) have no EGR valve and no catalytic converter, and 2002-2004 California trucks (RPO YF5) add an ECM-controlled EGR valve with a cooler plus a catalytic converter.\u003c\/p\u003e\n\u003ch2\u003eWhat fails and why\u003c\/h2\u003e\n\u003cp\u003eStart with heat, because on a Sierra that tows in Florida it shows up first. The early water pump has let its seal go as soon as 75,000 miles, and the LB7's radiator and fan are smaller than what GM fitted from 2006 on, so a fan clutch that free-wheels when hot, a cooling stack packed with grass and bugs, or a tired pump turns into a temperature gauge that climbs only on grades and in traffic. There are two thermostats in the crossover housing, front and rear, and they are different part numbers. If the upper hose goes rock hard, the overflow tank bubbles, or you lose coolant with nothing on the ground, stop looking at the cooling system and check the head gaskets: the original multi-layer steel gaskets usually give up past 100,000 miles, sooner on a truck that has been tuned or cooked, because the aluminum heads lift under cylinder pressure. While the hood is up, put a dial indicator on the harmonic balancer, since the rubber isolator degrades with oil and age and the outer ring starts to wobble; runout should stay under 0.005 in, and a failed balancer can throw the belt or break the crank snout.\u003c\/p\u003e\n\u003cp\u003eThe front end is next. The recirculating-ball box, pitman arm, center link and frame-mounted idler pivot were marginal for a 9,200-lb-GVWR truck when new, and once the idler and pitman pivots wear, the tie-rod angles change and tie rods bend or snap. More than an inch of free play at the wheel, wandering at highway speed and feathered tire wear are the tells, and leveling keys with 33- to 35-inch tires speed all of it up. A loose idler can move enough to rub the transmission cooler lines. Ball joints, control-arm bushings and hubs on the torsion-bar front end are usually due by 150,000 miles and much sooner on a leveled truck, and leveling keys installed without correcting upper-arm and ball-joint angle put the geometry out of spec and eat CV joints. On four-wheel-drive Sierras the transfer case has a failure all its own: the internal fluid pump slowly machines into the back half of the housing until it leaks, which is why shield kits exist. Check the RPO before ordering transfer-case parts.\u003c\/p\u003e\n\u003cp\u003eElectrical trouble on these trucks is usually voltage rather than parts. Two batteries feed the starter, the glow plug system with its heat-shielded controller, and an intake pre-heater, and when they are weak, mismatched or sitting on corroded grounds you get long cold cranking, white smoke that clears as it warms, Class 2 serial data faults with U0105 codes, a cluster that reads wrong, and sometimes a transmission that limps with nothing mechanically wrong. An aftermarket radio, especially a GPS head unit, can do the same thing. The Allison is strong at stock power, but the factory torque converter is its weak link: the thin stator cracks and the soft front cover balloons, which shows up as a shudder or rumble at steady throttle and burn marks on the flexplate bolt pads. Past roughly 80 to 100 hp over stock the five-speed flares on the 4-5 upshift and then locks into third with a P0700. Cooler lines weep at the crimped rubber sections, and the valve body gets sloppy as the long shift valves wear their bores. Last on this list but first in the LB7's reputation are the original Bosch injectors. They commonly go between 60,000 and 120,000 miles, while updated-design replacements are expected to run 150,000 to 250,000. Because they sit above the head's oil drains, a leaking injector or cup seal pushes fuel into the crankcase, so a rising oil level, a diesel smell on the dipstick and an analysis showing fuel over five percent are fuel-system symptoms, not oil problems. Under the same covers the injector harness chafes through its insulation and imitates a dead injector. On the supply side, filter-head O-rings and the hand primer seal let air in rather than fuel out, which reads as a hard start after the truck sits overnight and a primer that will not hold.\u003c\/p\u003e\n\u003ch2\u003eStock replacement vs. upgrade\u003c\/h2\u003e\n\u003cp\u003eMost of what an LB7 Sierra needs is OEM-grade maintenance done in the right order. Do the water pump, its housing and both thermostats in one visit because they share the labor, and budget for the large fan-clutch wrench. Replace the fan clutch and wash out the radiator and intercooler before you chase an overheat any further. Rebuild the fuel filter head with a fresh O-ring kit and prove it holds prime overnight before you condemn injectors or the CP3. Pressure-test or smoke-test the charge-air side before you buy a turbo, because most reports of a failing turbo on this engine end at a split boot, a soft coupler or a worn clamp, and a confirmed shaft-play or seal failure is best answered with a new or rebuilt OEM-spec RHG6 that keeps the certified configuration. Keep the Allison on fluid every 30,000 to 50,000 miles using DEXRON-VI, change the external spin-on filter every other oil change, and use genuine Allison solenoids when you are inside it. When injectors are due, do all eight as a set with new cups, copper washers, banjo seals and seal kits, and add the eight high-pressure lines past 150,000 miles. A lubricity additive and clean, dry fuel are cheap insurance on a common-rail system this sensitive.\u003c\/p\u003e\n\u003cp\u003eUpgrades earn their keep where GM left no margin. A frame-mount or in-tank lift pump takes the supply job off the CP3 and gives you water separation ahead of the injectors; it stops being optional once you add fueling, since more fuel without a lift pump drops rail pressure under acceleration and lets the pump cavitate. On the steering, heavy-duty tie rods, an idler support with tapered roller bearings and a fresh pitman arm are the repair that actually holds, and boxed upper control arms with matched ball joints keep a leveled truck in spec. For the transmission, a triple-disc converter with a billet stator is the first real upgrade, backed by a controller for line pressure and limp-mode control, new cooler line kits, and a tap shifter if you tow; a six-speed conversion is the long way around to a lower cruise rpm. Any time the heads come off, head studs replace the single-use torque-to-yield bolts, and remember that GM gaskets are side-specific and come in thickness grades chosen from measured piston protrusion, so measure before you order. Airflow is the other honest gain: an enclosed cold-air intake that keeps the MAF and its plate, a thicker bar-and-plate intercooler, aluminum charge pipes in place of the factory plastic, a high-flow intake horn, and cast manifolds with 2-inch stainless up-pipes and an uncrimped downpipe. On a YF5 California Sierra, keep \u003ca href=\"\/collections\/exhaust\"\u003eexhaust\u003c\/a\u003e work cat-back so the factory catalyst stays where it belongs, and order the EGR-compatible manifold and up-pipe kit.

The RPO sticker says whether the Sierra is FE9 (federal) or YF5 (California), and that one label decides exhaust manifolds, up-pipes and downpipe gaskets, because the California kit is a separate part number from 2002 on. Model year matters inside the platform too: a 2001 Sierra uses a different intake bridge and intercooler boot than a 2002-2004 truck, which is why boot kits are catalogued 2002-2004 only, while intercooler cores often span 2001-2005 and do carry over. Exhaust routing, gooseneck and fifth-wheel hardware follow cab and bed, across regular, extended and crew cab with 6.5-ft and 8-ft beds plus dual-rear-wheel 3500s, and a crew cab short bed generally wants a slider under a fifth wheel. Factory wheels are 16 x 6.5 steel on both trucks, but the offsets are not the same: single-rear-wheel Sierras run ET28 with about 4.84 inches of backspace while dual-rear-wheel 3500s run ET125 with 8.66 inches, both on the 8-lug 8x165.1 mm pattern with roughly a 116.7 mm center bore, so a DRW wheel will thread onto an SRW truck and still be the wrong part. The 2003 refresh is the other dividing line: front sheet metal, grille, bumper, headlight and tail light housings and the audio and HVAC trim all split there, so a 2001-2002 Sierra and a 2003-2004 Sierra are not the same truck to a lighting catalog, and DRW tail lights differ again from SRW. Hub and wheel bearing listings split 2001-2007 Classic from 2007.5-2010, so stay in the earlier range. Then the engine itself: GMC sold 2004 Sierras with either engine, so read the eighth digit of the VIN, where 1 is an LB7 and 2 is an LLY, before buying valve covers, injectors, a turbo or anything the ECM touches. LB7 injectors, lines and return hardware are LB7-only, and the LLY's injectors are longer and mount outside the covers. Two trucks this page is not for: the LB7 came only in the 2500HD and 3500, never a 1500 or 1500HD, and the 2003-2004 TopKick C4500\/C5500 used the LB7 under the LRY medium-duty option at 210 hp at 2,750 rpm and 520 lb-ft at 1,600 rpm, so pickup listings should not be assumed to carry over to it. When anything is uncertain, verify by VIN.\u003c\/p\u003e\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eMy Sierra wanders at highway speed and the steering feels loose. What is worn?\u003c\/h3\u003e\n\u003cp\u003eOn a GMT800 HD it is almost always the idler and pitman pivots first, and then the tie rods they pull out of line. More than an inch of free play at the wheel, feathered tire wear and a visibly bent tie rod all point the same way, and a loose idler can move far enough to rub the transmission cooler lines. Heavy-duty tie rods plus an idler support kit fix it properly; new tie rods on worn pivots will bend again.\u003c\/p\u003e\n\u003ch3\u003eWhy does my Allison lock itself into third gear?\u003c\/h3\u003e\n\u003cp\u003eThat is limp mode. The TCM drops to third, commands maximum line pressure and cuts solenoid voltage, and it sets a P0700 along with whatever slip or ratio codes it logged. On a stock Sierra it usually means the transmission is genuinely due; on a tuned one it turns up quickly past roughly 80 to 100 hp over stock. Check batteries, grounds and cranking voltage first, because a Class 2 data fault can put the box in limp with nothing actually slipping.\u003c\/p\u003e\n\u003ch3\u003eWill 2001 charge-pipe boots fit my 2003 Sierra?\u003c\/h3\u003e\n\u003cp\u003eNo. The 2001 trucks use a different intake bridge and a different intercooler boot, while 2002, 2003 and 2004 take a straight boot and different pipe lengths. That is why boot kits are listed 2002-2004 rather than 2001-2004. Intercooler cores are the looser part here, since those listings often cover 2001-2005, but confirm the boots and pipes separately from the core.\u003c\/p\u003e\n\u003ch3\u003eMy Sierra cranks but will not start and the gauges read wrong. Where do I look?\u003c\/h3\u003e\n\u003cp\u003eVoltage and the data bus, in that order. Low cranking voltage from weak or mismatched batteries and corroded grounds corrupts the Class 2 serial network, which sets U0105 and makes the cluster report nonsense. Load-test both batteries together, clean every ground and measure voltage drop across the main cables while cranking. If an aftermarket radio or GPS unit was installed, pull its fuse to rule it out before you buy modules.\u003c\/p\u003e\n\u003ch3\u003eWhat is the fuel filter interval on an LB7?\u003c\/h3\u003e\n\u003cp\u003eThe frame-mounted filter is the ACDelco TP3018 and the LB7 schedule calls for it every 15,000 miles. Oil is 10 quarts with the filter on a 10,000-mile or twelve-month interval, or whenever the oil-life monitor calls for it, and the air filter is a 45,000-mile item. On a truck with no factory lift pump, that filter head is the only thing standing between the tank and a set of injectors, so do not stretch the interval.\u003c\/p\u003e\n\u003ch3\u003eCan my Sierra 3500 pull 15,000 pounds?\u003c\/h3\u003e\n\u003cp\u003eRatings for these trucks run around 12,000 lb conventional and 15,800 lb fifth-wheel, but they move with cab, bed, two- or four-wheel drive and axle ratio, so read the label on the door jamb rather than a generic figure. The five-speed Allison is the part that feels heavy work: transmission heat and gear hunting on grades are the usual complaints, which is why a tap shifter, cooler line upgrades and a better converter are the common towing additions.\u003c\/p\u003e\n\u003cp class=\"sds-copy-cta\"\u003eNot sure what fits?

On the LB7, the early water pump seal design was a documented failure, as early as 75,000 miles. On the LMM, water pumps seep at the weep hole and leave crusty residue as they age and heat-cycle. On the L5P, the plastic upper radiator hose fittings and the edges of the coolant reservoir can crack after long heat exposure, which leaves orange DEX-COOL residue and a sweet smell. If the system is hard and pressurized after shutdown, or the overflow tank bubbles, look at the head gasket instead. A wet, crusted rear cover is the leak this plate fixes.\u003c\/p\u003e\n\u003ch2\u003eWhat you get\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eBillet coolant block off plate, Fleece part number FPE-DMAX-CBOP\u003c\/li\u003e\n\u003cli\u003eIntegral O-ring seal built into the plate\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eAbout Fleece Performance Engineering\u003c\/h2\u003e\n\u003cp\u003eBrothers Brayden and Chase Fleece started Fleece Performance Engineering in 2008, and the company is headquartered in Pittsboro, Indiana.

There is no other torque converter offered anywhere that can make this claim. The 30 square drive tabs that are precision CNC cut into the billet cover is only one of the many patented aspect of the TripleLok converter.\u003c\/p\u003e\n\u003cp\u003eATS engineered a unique two piece design that not only allows us to cut precision radial flank drive lugs into the cover but also utilizes a plasma weld ensuring an unmatched quality standard. The patented radial flank drive tabs virtually eliminate the wear that is common with all other round tab multi-disc torque converters. This is the number one reason ATS can offer a 5 year warranty on all our torque converters.\u003c\/p\u003e\n\u003cp\u003eThere are a few things that I would like to tell you about this torque converter. In 1999 the first Diesel multiple disc converter was developed utilizing round tabs to connect the clutch plates to the cover. We soon realized this to be a problem, after several thousand miles the outer plate would start to hammer into the billet cover due to the engine piston pulsations. These pulsations are engine torsional loads that will destroy a converter and flex plate.\u003c\/p\u003e\n\u003cp\u003eWe soon invented and patented the Square tab design that you can see and only get from ATS today. The Radial Flank Square Tab is the back bone of the ATS TripleLok and FiveStar torque converter, all ATS multiple Disc converters are 100 percent square tab construction. The Billet cover provides a multitude of benefits, having the thick steel cover provides a base that will not flex. This is very important when needing a flat surface for the Lock-up clutches to couple with, this is also very important during times when there are high pressures created inside the converter due to extended load times when the converter is in a vortex flow. This pressure will cause the converter to balloon and the thrust bearings to get out of alignment causing converter failure.\u003c\/p\u003e\n\u003cp\u003eThe triple clutch lock-up system is used to transfer torque from the engine to the transmission during high power applications when the converter is in lock-up. The triple clutch provides three times the torque capacity of a standard single disc converter and ensures there will be no slipping during hard accelerations or when pulling heavy loads. There are basically two areas of operation in a torque converter. The fluid coupling portion and the lock-up portion.\u003c\/p\u003e\n\u003cp\u003eThe fluid coupling section is the operation that takes place when you accelerate from a stop when the engine is spinning and the vehicle wheels are not moving or just starting to move. As you push on the accelerator pedal and the vehicle starts to move this is considered the torque converter stall speed. Once the stall speed is reached and the vehicle starts to move forward the converter is in what we refer to as the Vortex flow condition of the converter cycle. The Vortex flow cycle is one of the most important and overlooked segments of a converter.\u003cbr\u003e\u003cstrong\u003eDetails:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTripleLock Torque Converter\u003c\/li\u003e\n\u003cli\u003eFactory RPM Stall Speed\u003c\/li\u003e\n\u003cli\u003eCast Stator\u003c\/li\u003e\n\u003cli\u003ePositive Impeller\u003c\/li\u003e\n\u003cli\u003eBillet Cover with Patented square Flank Drive\u003c\/li\u003e\n\u003cli\u003eSquare Tab Construction (Not Round)\u003c\/li\u003e\n\u003cli\u003eTriple Disc CNC Laser Cut Clutch Plates\u003c\/li\u003e\n\u003cli\u003eBillet Piston with Patented flank drive tab design\u003c\/li\u003e\n\u003cli\u003eProprietary ATS exclusive Clutch Formulation with unique bonding technology (ensures 100 percent chemical Bond)\u003c\/li\u003e\n\u003cli\u003eRedesigned Spring Dampener supports increased extend torque loads\u003c\/li\u003e\n\u003cli\u003e4340 Hardened turbine splines provide longevity due to engine torsional stress\u003c\/li\u003e\n\u003cli\u003eFully Welded Turbine and Impeller Vanes\u003c\/li\u003e\n\u003cli\u003eCNC Stator with High Flow Windows Increase Oil Flow providing increase efficiency\u003c\/li\u003e\n\u003cli\u003eFull Roller Bearing Construction Between High Load Areas\u003c\/li\u003e\n\u003cli\u003e340 CNC cut Pump Drive Hub lock into Impeller Housing and Plasma welded for unsurpassed strength\u003c\/li\u003e\n\u003cli\u003eSold Individually\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eFits:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e2001-2010 GM 2500|3500 Truck w\/6.6L Duramax Engine and Allison LCT-1000 Transmission\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ATS Diesel Performance","offers":[{"title":"Default Title","offer_id":49824548061472,"sku":"302-930-4248","price":1299.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0916\/3043\/6640\/files\/ats-diesel-performance-ats-302-930-4248-triplelok-performance-torque-converter-factory-stall-speed-allison-lct1000-2001-2010-gm-66l-duramax-9262414.jpg?v=1779551469"},{"product_id":"ats-allison-deep-transmission-pan-fits-2001-2018-6-6l-duramax","title":"ATS 301-900-4248 Allison Deep Transmission Pan (2001-2018 6.6L Duramax)","description":"\u003cdiv class=\"sds-pd-intro\"\u003e\u003cp\u003eThe ATS 301-900-4248 Allison Deep Transmission Pan replaces the factory pan on the Allison 1000 automatic behind the 6.6L Duramax in 2001-2018 Chevrolet Silverado and GMC Sierra 2500HD and 3500HD pickups.

On the LML, sustained slip while towing on grades heat-soaks the clutch packs, and the C3 clutch only receives fluid when it is applied, so it runs hot. For 2011-2016 trucks, normal transmission temperature is 175-195 F, 205-215 F when towing, with 240 F as the max; a transmission that consistently runs above 220 F is a red flag.\u003c\/p\u003e\n\u003cp\u003eA deep pan paired with an auxiliary cooler is a common way to keep towing temperatures under about 215 F, and BD Diesel lists a deep pan with filter among its heat fixes for the Allison. This ATS pan holds an extra 5 quarts of fluid over stock, which gives you more fluid in the system on a long pull.
