| Unfortunately, old transmissions seldom improve with age. Internal synchronizers get worn, gaskets leak, mounts deteriorate, and filters clog, making gears changes rough or causing it not to shift at all. Transmission repair can sometimes be intimidating because of the special tools often required and tight tolerances that must be met, but if you're comfortable with engine work, then this is not too dissimilar. However, the key element to any job on a precisely engineered vehicle is to use original quality parts, all of which are available in this section. |
