2008–2010 Chevrolet Colorado 4WD Shop Manual (P/N 1542655)

• Coverage is limited to the 2009 4WD Canyon/Colorado VIN S/T platform, including the Chevrolet Colorado Pickup and GMC Canyon. The archive is a 4,590-page PDF collection in 165 files; 45 pages are duplicate T150 split-chapter copies, leaving 4,545 unique pages.
• Engine repair material is organized for the 2.9L LLV (VIN 9), 3.7L LLR (VIN E), and 5.3L LH8 (VIN L). It covers on-vehicle service, removal and installation, full off-vehicle disassembly and assembly, timing-system work, cylinder-head and valvetrain repair, lubrication components, crankshaft and piston service, inspection, and thread repair.
• Transmission and 4WD sections document the shared 4L60-E/4L65-E/4L70-E automatic-transmission family, the Aisin AR5 manual transmission, the Isuzu T150 transfer case, front and rear drive axles, propeller shafts, and wheel drive shafts. Procedures range from unit replacement and seal service to internal teardown, inspection, reassembly, end-play checks, and adjustment.
• Brake and chassis coverage runs from hydraulic, disc, drum, and parking-brake repair to ABS automated bleeding, EBCM/BPMV replacement, wheel-speed-sensor service, yaw-rate-sensor replacement and reset, steering, suspension, and tire-pressure-monitor work. Separate files identify the NW7 traction-control and JL4 vehicle-stability configurations.
• Electrical, body, HVAC, and restraint files provide power and ground distribution, Class 2 serial-data and high-speed GMLAN schematics, cab-specific harness routing, transfer-case controls, engine-control wiring, SIR circuits, lighting, body-control, immobilizer, instrument, window, seat, trim, frame, underbody, and pickup-box repair information.
• Content is organized into more than 1,200 factory repair-instruction documents, 108 specification documents, 53 component-location or visual-identification documents, and more than 150 schematic and routing sheets. The specification material includes 46 Fastener Tightening Specifications sections, along with test and adjustment data, inspection specifications, exploded views, and GM special-tool callouts.

Exact Powertrain Identification

The engine files distinguish the 2.9L LLV, 3.7L LLR, and 5.3L LH8 applications rather than treating all Colorado powertrains as interchangeable. The 5.3L material appears under GM's shared “4.8L, 5.3L, 6.0L, 6.2L, or 7.0L” mechanical chapter heading, but the vehicle specification identifies the covered truck application as the 5.3L LH8.

Automatic-transmission material uses the shared 4L60-E/4L65-E/4L70-E chapter and covers the torque converter, pump, valve body, servos, clutch packs, planetary components, shafts, seals, and case. The Aisin AR5 files provide on-vehicle and off-vehicle repair procedures, disassembled views, and specifications. Starting-system schematics separately identify the M30 automatic and MA5 manual configurations.

Isuzu T150 Transfer Case Repair

The T150 material goes well beyond a single parts picture. GM Document ID 1542655 is the “Case Components” locator; Document ID 1105988 maps the internal planetary carrier, drive chain, shafts, synchronizer, shift forks, oil-pump parts, bearings, and seals. On-vehicle procedures address transfer-case replacement, fluid service, the encoder motor, speed sensor, neutral and indicator switches, vent hose, adapter, and front, rear, and input-shaft seals.

The off-vehicle chapter covers disassembly, cleaning and inspection, internal component service, case assembly, and seal installation. Named tooling includes the J 45759 Assembly Fixture, J 45933 Isuzu Transfer Case Assembly/Disassembly Kit, J 37212 Front Output Shaft Seal Installer, J 35582 Oil Pump Seal Installer, and J 45934 Input Seal Installer.

Brakes, Wiring, and Structural Work

ABS files locate the brake pressure modulator valve, electronic brake control module, wheel-speed sensors, traction-control switch, longitudinal accelerometer, and yaw-rate sensor. They also cover automated bleeding and the scan-tool reset following yaw-rate-sensor replacement. Related chapters handle master-cylinder, booster, pipe, hose, caliper, wheel-cylinder, drum, disc, and parking-brake repair.

Useful diagram examples include Transfer Case Encoder Motor, ABS – Vehicle Stability – JL4, Data Communication – Highspeed GMLAN, Body Harness Routing 1 of 3 (Crew Cab), Timing Chain Alignment Diagram, and Control Valve Body Assembly exploded views. Structural files cover pickup-box, door, hood, fender, hinge, latch, window, bumper, fascia, frame, and underbody work, along with SIR collision inspections.

Important Scope and Repair Notes

This collection concentrates on factory repair instructions, specifications, component locators, exploded views, and wiring or routing material. It is not a complete reproduction of every service-manual section: full DTC diagnostic charts, Description and Operation chapters, scheduled-maintenance schedules, and the Preface warnings referenced by some procedures are not included.

The T150 assembly material warns that excessive flange sealant can block the oil-pump screen and cause internal component failure. Brake procedures specify clean approved DOT-3 fluid because contamination can damage hydraulic-system seals and linings.

Brake hydraulic work, SIR service, fuel-system procedures, and engine or transmission removal require proper vehicle support, pressure relief, electrical isolation, and the specified scan-tool procedures before repair work begins.
