The drive plate (ywheel) will not support a load. None of the weight of the transmission
must be allowed to rest on the drive plate during removal or installation.
The transmission and torque converter must be removed and installed
as an assembly to prevent damage to the front bushing or front oil seal.

Starting at rear of pan and working toward front, loosen attaching bolts and allow
uid to drain. Finally remove all of pan attaching bolts except two at front to allow

temporarily hold it in place.

Matchmark torque converter with drive plate (for easier installation).
Do not attempt to rotate the drive plate or torque converter by prying or
using force or you will damage the drive plate.

attaching bolt to turn converter to gain access to bump switch.
