First of all, before any repairs are to be conducted, it is necessary to establish whether there is an electric or hydraulic problem in the equipment. To diagnose a trouble, one must have an understanding on how a transaxle operates and its components, and also access to some unique test equipment. Automatic transaxle problems should be diagnosed at the dealer service department or any other qualified repair facility. Also, do not remove a faulty transaxle until a knowledgeable technician with appropriate tools has evaluated the vehicle because troubleshooting requires the transaxle to remain in place.

If the transaxle requires major repair work, it should be left to a dealer service department or an automotive or transmission repair shop. If you've decided that the transaxle must be removed for overhaul or major repair work, several preliminary steps should be taken. Read all removal and installation procedures carefully prior to committing this job. Transaxle removal involves removing the engine and transaxle as an assembly. For removal, first, drain the transaxle fluid. Then, remove the engine/transaxle assembly, and separate the transaxle from the engine. For installation, it is the reverse of removal, noting the following points: Prior to installation, make sure the torque converter is fully engaged in the transmission. To do this, rotate the converter while pushing it towards the transaxle. If it wasn't already fully in place, you'll feel it "clunk" into position as it engages with the input shaft and front pump. It may even "clunk" more than once. Lubricate the torque converter hub with multi-purpose grease. Move the transaxle forward carefully until the dowel pins and the torque converter are engaged. Make sure the marks on the torque converter and drive plate are in alignment. Install the transaxle-to-engine bolts. Tighten the bolts to the specified specific torque. Install the engine/transaxle assembly. Lower the vehicle. Install and adjust the shift cable. Fill the transaxle with the recommended type and amount of fluid, run the vehicle and check for fluid leaks.
