GM 24252997 Transmission Assembly, Man

An overhaul of a manual transmission is quite complex as a DIY project; it involves dismantling and assembling not only a large number of small components but fine shimming of clearances, which may require the use of such items as select-fit spacers and snap-rings. If problems do develop with a manual transmission system, it is relatively easy for a competent do-it-yourselfer to pull the transmission and re-install it: the overhaul process is not typically one a home mechanic would undertake since time and costs associated with it are usually higher than a simple replacement, although used rebuilds are sometimes available through dealer parts departments and auto parts stores. Any naive and ill-prepared person, given the proper set of special tools, can rebuild a transmission if he or she does not miss a single step of the process. Tools necessary for the overhaul can be internal and external snap-ring pliers, bearing puller, slide hammer, set of pin punches, dial indicator and may be a hydraulic press as well as a large workbench and a vise or transmission stand. When disassembling a system, it is relevant to write down the sequence of part removal, where they were located, and how they were fixed. Knowledge of the area that is not functioning properly may aid in analysis and repair of transmission, since some of the problems can be associated with definite section of the transmission.
