ASSEMBLY

Special Tools:














NOTE: If the transmission assembly is being reconditioned (clutch/seal replacement) or replaced, it is necessary to perform the Quick Learn Procedure using the scan tool TCM Quick Learn.




42RLE BEARING ORIENTATION









1. Install the output bearing cups using Installer.










2. Install low/reverse piston retainer gasket (2).










3. Install low/reverse piston retainer (1).










4. Install low/reverse piston retainer-to-case screws (3) and torque to 5 Nm (45 in. lbs.).










NOTE: The Low/Reverse Clutch Piston has bonded seals which are not individually serviceable. Seal replacement requires replacement of the piston assembly.

5. Install low/reverse clutch piston (1).










6. Assemble guide bracket (1) assembly as shown, if necessary.










CAUTION: When installing, be sure guide bracket and split sleeve touch the rear of the transmission case.

7. Install guide bracket pivot pin (1).
8. Install park sprag pivot retaining screw and torque to 4.5 Nm (40 in. lbs.).










9. Install low/reverse piston belleville spring (1) into position.










10. Install and load low/reverse spring with compressor tool (3), (4) and disc (5) as shown in to facilitate snap ring (2) installation.










11. Install snap ring (1) and remove compressor tool.










12. Install rear carrier (4) front bearing cone.










Check output bearing preload. Output bearing preload must be checked and/or adjusted if any of the following items have been replaced:

- Output shaft (rear carrier assembly)
- Output shaft bearings
- Transmission case

13. PRELOAD CHECK/SHIM SELECTION: Install rear output shaft bearing cone and Support Plate (1).










14. Install Support Plate (1). Lightly tighten retaining screws. Screws should be below the plate surface, but do not snug screws.
15. Turn case over on arbor press so that the plate is resting on the press base. CAUTION: The output shaft will extend through the hole of Support Plate. Ensure your press table has clearance for the output shaft.










16. Install shim (1) on output shaft (2). Apply small amount of petrolatum onto the shim to hold it in place. Use the original shim as a starting point. If original shim is not available, use the thickest shim available.










17. Install output shaft/rear carrier into rear bearing. The shaft must be pressed into position. Use Disc (2) and Universal Handle and Handle Extension (1) to press shaft into rear bearing.










CAUTION: Do not re-use old output shaft nut because the removed stake weakens the nut flange. Using Wrenches and , install new output shaft nut. Tighten new output shaft nut to 271 Nm (200 ft. lbs.).

18. Check the turning torque (1) of the output shaft. The shaft should have 1 to 8 in. lbs. of turning torque. If the turning torque is higher than 8 in. lbs., install a thicker shim. If turning torque is less than 1 in. lb., install a thinner shim. Make sure there is no end play.










CAUTION: Failure to stake nut could allow the nut to back-off during use.

19. The new nut (3) must be staked after the correct turning torque is obtained. Use Staking Tool (2) to stake output shaft nut.










20. Verify that the nut has been properly staked to the output shaft.










21. Install low/reverse clutch pack (1, 2). Leave uppermost disc out to facilitate snap ring installation.










22. Install low/reverse reaction plate snap ring (2).










23. Install one low/reverse clutch disc (1).
