On-Vehicle Service















^ Tools Required:
- J 36842 Transmission Holding Fixture
- J 3289-20 Bench Mount Holding Fixture Base


REMOVE OR DISCONNECT

CAUTION: Before removing or installing any electrical unit or when a tool or equipment could easily come in contact with "live" exposed electrical terminals, disconnect the battery negative cable assembly to help prevent personal injury and/or damage to the vehicle or components. Unless instructed otherwise, the ignition switch must be in the "OFF" or "LOCK" position.

1. Battery negative cable.
2. Front floor console trim plate.
3. Raise and suitably support vehicle.
4. Clutch actuator cylinder line from actuator.
5. Drain fluid from 5-speed manual transmission (2).
6. Propeller shaft.
7. Support rear axle with jack stand.
8. Rear axle torque arm.
9. Catalytic converter hanger.
10. Wiring harness connector from backup lamp switch (4).
11. Wiring harness connector from speed sensor (12).
12. Support engine with a jack stand.
13. Support 5-speed manual transmission (2) with jack stand.
14. Transmission support and transmission mount.
15. Lower 5-speed manual transmission (2), enough to reach transmission control bolts/screws (19), with aid of helper.
16. Transmission control bolts/screws (19).

NOTICE: Manual transmission control must be held when lowering manual transmission, as control is not retained in vehicle. If control is not held it could drop causing damage to the component.

17. Lower 5-speed manual transmission (2).
18. Manual transmission control (21).
19. Transmission bolts/screws (41).
20. 5-speed manual transmission (2) from flywheel housing (45) with aid of helper.
21. Place 5-speed manual transmission (2) in J 36842.

INSTALL OR CONNECT

NOTICE: Always use the correct fastener in the correct location. When you replace a fastener, use ONLY the exact part number for that application. The manufacturer will call out those fasteners that require a replacement after removal. The manufacturer will also call out the fasteners that require thread lockers or thread sealant. UNLESS OTHER WISE SPECIFIED, do not use supplemental coatings (paints, greases, or other corrosion inhibitors) on the threaded fasteners or fastener joint interfaces. Generally, such coatings adversely affect the fastener torque and the joint clamping force, and may damage the fastener. When you install fasteners, use the correct tightening sequence and specifications. Following these instructions can help you avoid damage to parts and systems.

Clean
- Sealant from manual transmission extension housing.
- Sealant from control (21), if reinstalling.

1. Control (21) to installed position on vehicle.
2. 5-speed manual transmission (2) to flywheel housing (45), with aid of helper.
- Pilot splined input shaft (53) into clutch disc hub and pilot bearing.
3. Support 5-speed manual transmission (2) with jack stand.
4. Transmission bolts/screws (41).

Tighten
- Transmission bolts/screws (41) to 75 Nm (55 ft. lbs.).

5. Apply a continuous 3 mm (1/8-inch) bead of RTV Sealant GM P/N 12345739, or equivalent to manual transmission extension housing-to-control sealing surface.
6. Raise 5-speed manual transmission (2) up engaging manual transmission control (21).
7. Transmission control bolts/screws (19).

Tighten
- Transmission control bolts/screws (19) to 20 Nm (15 ft. lbs.).

8. Raise 5-speed manual transmission (2) to installed position.
9. Transmission support and transmission mount.
10. Remove jack stands from transmission and engine.
11. Wiring harness connector to speed sensor (12).
12. Wiring harness connector to backup lamp switch (4).
13. Catalytic converter hanger.
14. Rear axle torque arm.
15. Remove support from rear axle.
16. Propeller shaft.
17. Clutch actuator cylinder line to actuator.

Important:
- Make sure the braced actuator line is not twisted or kinked. Line must be maintained away from other components to avoid damage to the line.
- Quick connect fitting must be pushed on, then pulled back to verify engagement. Do not rely on audible click or visual verification.

18. Bleed clutch hydraulic system.
19. Check and fill manual transmission with fluid
20. Lower vehicle.
