Manual transmission rebuild is not easy for a DIY mechanic as many tiny parts have to be removed and assembled with an accuracy in measurements of clearance that may call for use of select fit spacers and snap-rings. In the case of problems, a competent do-it-yourselfer can remove and reinstall the transmission because overhaul entails a long time which is costly and may be in excess of a rebuilt transmission, which can be ordered from the dealer's parts department or auto parts stores. Nonetheless, an inexperienced mechanic can pass a reconstruction of the transmission if such spare tools are accessible, and the general reconstruction of the transmission is conducted step by step so that none of the details of the process are omitted. The overhaul of the unit will require several tools including internal and external snap ring pliers, a bearing puller, slide hammer, set of pin punches, dial indicator, a possibly hydraulic press, and a big solid table and a vice or a transmission stand. In the process of disassembly, it is quite important to record observations regarding how a particular component is disconnected and where it is located relative to other parts, and how it can be fastened. It is important to have proper knowledge of possibly problematic areas of the transmission since some problems are associated with particular zones of the transmission.
