Overhauling a manual transaxle is a very difficult task for the average home mechanic. It requires disassembly and assembly of a very large number of small parts. It is necessary to maintain very precise clearances and change them, if necessary, by installing new shims or snap rings. Therefore, if the transaxle develops problems, the average home mechanic may remove and install the transaxle, but overhaul should be left to specialists. You can also purchase a rebuilt transaxle; look in the auto market or at repair shops. In any case, the time and money spent on overhauling the transaxle yourself almost always exceed the cost of buying a rebuilt unit.
Nevertheless, a home mechanic who has the necessary equipment can rebuild the transaxle if the work is performed carefully and in sequence.
Tools required for transaxle overhaul include pliers, pullers, a slide hammer, a set of punches, a dial indicator and possibly a hydraulic press. A large, stable workbench and a vise are also required.
When disassembling the transaxle, note the installation position of all components to make assembly easier and more accurate. Diagrams showing the manual transaxle components are provided in this chapter (see Manual Transaxle Components 1, Manual Transaxle Components 2 and Manual Transaxle Components 3).
Before beginning transaxle disassembly, it is advisable to have a general idea of which part of the transaxle has failed. Some problems may be caused by faults in specific areas of the transaxle, which can greatly simplify inspection and replacement of faulty components. Refer to Subsection 1.9 for additional information.
