The converter driveplate, pump bushing, and oil seal are best changed as a complete unit, the transmission and torque converter cannot be successfully separated as such. Start with the detachment of the negative battery terminal, followed by lift of the car using jack stands, and removal of any pans or trays in the under part of the car. No longer circulate the old transmission fluid and do away with exhaust parts that hinder its elimination. Locate the relation between the torque converter and driveplate using the inspection plug hole, also remove the starter motor and the bell housing covers. Remove the torque converter to drive plate bolts, lift the transmission with the jack and remove the mounts and cross member bolts. Lower the transmission slightly for access to the components, remove the shift cable, electrical connectors, heat shield and the fuel line bracket. Remove the transmission cooler lines, the bolt screwing into the fill/dipstick tube, and if necessary the transfer case. Support the engine, unbolt the transmission to the engine and lock the torque converter with the locking pliers so that it doesn't fall off. To install make sure that the torque converter is well locked into the pump, lift the transmission above and make sure the holes in the torque converter line up with the driveplate holes. Slide the transmission forward until it is fully mated, reinstall the dipstick tube, replace the transmission to engine bolts, and reinstall the crossmember. Check and reconnect the torque converter to driveplate bolts, reinsert the starter motor and check that the retaining rings are correctly fitted in quick connect fittings. Some of the tasks that are followed in the process include connecting the transmission fluid cooler lines, plugging of electrical connectors and the installation of heat shield. Engage the shift cable, replace the torque converter inspection cover, and if necessary replace the transfer case, and driveshafts. Last, reposition the shift cable, returned all removed exhaust parts, reduce height of the vehicle, and fill the transmission with the called type of the fluid and start the engine for one hour or more to make sure that there is no leakage.
