Special Tool(s) : 307-589 Overdrive clutch and balance piston service setNOTE: Install the overdrive clutch piston return spring so that the holes are facing upward.
NOTE: Install the low/reverse piston return spring with the tabs facing down.
NOTE: Make sure the snap ring is fully seated in the groove before releasing the pressure on the return spring.
Special Tool(s) : 307-584 2-6 Spring Compressor , 307-588 Reverse clutch piston and retaining ring setNOTE: Make sure the snap ring is fully seated in the groove before releasing the pressure on the return spring.
Special Tool(s) : 307-584 2-6 Spring CompressorNOTE: Note the location of the Torx® head and the hex head bolts for assembly.
NOTE: Install the Torx® and the hex bolts in the correct locations as noted during disassembly.
Hand tighten.NOTICE: The solenoid body should be handled with care or damage to the solenoid body may occur.
NOTICE: Do not handle the solenoid body in the internal wiring harness frame area or by the screens of the solenoid body filter or damage to the solenoid body may occur.
NOTICE: Use care not to break the alignment tabs when installing the solenoid body filter. Damage to the transmission will occur if the solenoid body is not correctly aligned.
Pull straight up from the alignment tabs.NOTICE: Do not handle the solenoid body in the internal wiring harness frame area or by the screens of the solenoid body filter or damage to the solenoid body may occur.
NOTICE: Use care not to break the alignment tabs when installing the solenoid body filter. Damage to the transmission will occur if the solenoid body is not correctly aligned.
NOTICE: Make sure that the filter passage areas are clean of foreign material before installing the filter. Damage to the transmission will occur if the filter passages are not clean.
