The ease of repairing a Muncie transmission makes it a good do-it-yourself project. A thorough rebuild of the transmission is often a good idea, as this prevents frequent repairs, which are likely in old transmissions. A repair or rebuild requires a gear rebuild kit and a new shifter and shifter installation kit if you need to replace the gear shifter.
A thorough cleaning of the transmission is required, owing to the years of accumulated oil and dirt in an old four-speed such as the Muncie. Carefully inspect every part of the transmission during repairs. A reliable guide or manual is helpful during this process. Order a new part if the old one isn't satisfactory; for instance, fresh bearings and synchronizers can improve the drivability of the vehicle. As of 2015, there are a number of companies that offer replacement options for various components, some of which are much stronger than the originals.
Use a quality, high-temperature grease for adhesion, as this saves repairs down the road. Use new external shifter shaft seals to resolve leaks in the transmission. During installation of a new gear shifter, make sure you have the shift gear orientation correct for each gear, or your first gear may be second, your third could be fourth, and so on.Learn more about Transmission
