Repairing a manual transmission is a difficult task for a novice auto mechanic. In addition to the fact that you will need to remove and install a large number of small parts, you will need to accurately measure and, if necessary, adjust numerous gaps by selecting gaskets. Therefore, it is recommended to entrust the overhaul of the transmission to a specialist or purchase an already rebuilt unit.
However, a car enthusiast with some experience and special tools can completely overhaul the transmission on his own. Work carefully and methodically so as not to miss anything.
The tools needed for rebuilding are pliers for removing the inner and outer locking ends, bearing pullers, a sliding hammer, a set of punches, a dial micrometer, and possibly a hydraulic press. In addition, a large, sturdy workbench and a vice will be needed.
While disassembling the transmission, carefully record the location of each component to facilitate subsequent installation.
Before disassembling the transmission, try to find out which of its components is malfunctioning (see Chapter "Troubleshooting").
