DISASSEMBLY

NOTE: If the transmission is being reconditioned (clutch/seal replacement) or replaced, it is necessary to perform the Quick Learn Procedure using the DRBIII® Scan Tool (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES/TRANSMISSION CONTROL MODULE - STANDARD PROCEDURE).

Before disassembling transmission, move the shift lever clockwise as far as it will go and then remove the shift lever.

NOTE: Tag all clutch pack assemblies, as they are removed, for reassembly identification.

CAUTION: Do not intermix clutch discs or plates as the unit might then fail.

NOTE: The four bolts along the bottom of the adapter housing have a sealing patch applied from the factory. Note the locations of these bolts and separate these bolts for reuse.

NOTE: There are two pry slots located near the bottom corners of the housing for separating the housing from the transmission case

NOTE: One of the oil pan bolts has a sealing patch applied from the factory. Separate this bolt for reuse.

CAUTION: Do not handle the valve body by the manual shaft. Damage could result.

NOTE: The oil pump bolts are not to be reused.

CAUTION: By-pass valve must be replaced if transmission failure occurs.

NOTE: The number seven needle bearing has three antireversal tabs and is common with the number five and number two position. The orientation should allow the bearing to seat flat against the rear sun gear .

NOTE: Verify that Compressor 5058A is centered properly over the 2/4 clutch retainer before compressing. If necessary, fasten the Compressor 5058A bar to the bellhousing flange with any combination of locking pliers and bolts to center the tool properly.

NOTE: The 2/4 Clutch Piston has bonded seals which are not individually serviceable. Seal replacement requires replacement of the piston assembly.

CAUTION: Failure to grind and open stakes of the output shaft nut will result in thread damage to the shaft during nut removal.

WARNING: Wear safety goggles while grinding stake nuts.

Use Remover 6596 with a press to remove the front output shaft bearing cup .

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