Transmission Removal

NOTE: After transmission is removed for a major overhaul, it is important to completely clean all transmission components, including torque converter (7902) , transmission oil cooler (7A095), transmission oil cooler inlet tube (7A030), main control valve body (7A100) , clutches and all coasting booster valve shuttle balls (7E195) after any transmission service that generates contamination. These contaminants are a major cause for recurring transmission concerns and must be removed from the system before the transmission is returned to service.

The cleaning of debris from the direct clutch check ball is often omitted. This omission can lead to a repeat servicing of the transmission.

Cleaning and flushing procedures for transmission components, including the direct clutch check ball, can be found in this Section listed under Cleaning and Inspection.

1. Open hood and disconnect the battery ground cable (14301).

2. Raise vehicle on a hoist. Refer to Section 00-02.

3. Remove muffler inlet pipe and resonator (5A289). Refer to Section 09-00.

4. Drain transmission fluid as outlined.

5. Remove the converter access cover and clip from the engine oil pan (6675).

    CAUTION: Care should be taken not to damage cooler lines.

    CAUTION: Never rotate the crankshaft pulley (6312) in a counterclockwise direction (as viewed from the front).

6. Remove the four flywheel-to-converter retaining nuts by placing a 22mm socket and breaker bar on the crankshaft pulley retaining bolt. Rotate the crankshaft pulley clockwise (as viewed from the front) to gain access to each of the nuts.

7. Remove driveshaft. Refer to Section 05-01.

8. Disconnect and remove the vehicle speed sensor (VSS) (9E731) from the extension housing (7A039).

9. Disconnect the transmission wiring harness connectors.

10. Remove starter-to-converter housing retaining bolts and position starter motor (11002) out of the way.

11. Position a transmission jack under the transmission and raise it slightly.

12. Remove the engine rear support-to-crossmember bolts.

13. Remove the crossmember-to-frame side support retaining bolts and remove the engine and transmission support insulator (6F063) and engine and transmission support (6F065) and engine damper mounting body bracket (6F067).

14. Lower the jack under the transmission and allow the transmission to hang.

15. Position a jack to the front of the engine and raise the engine to gain access to the two upper converter housing-to-engine retaining bolts.

16. Disconnect the oil cooler lines at the transmission. Plug all openings to keep dirt out.

17. Remove the lower converter housing-to-engine retaining bolts.

18. Remove the transmission oil filler tube (7A228).

19. Secure the transmission to the jack with a safety chain.

20. Remove the two upper converter housing-to-engine retaining bolts. Move the transmission to the rear so it disengages from the dowel pins and the torque converter is disengaged from the flywheel (6375). Lower the transmission from the vehicle.

    NOTE: If the transmission is to be removed for a period of time, support the engine with a safety stand and wood block.

21. Remove torque converter from transmission.
