Transmission & Differentials

Transmission general notes:

The MGT tranny is fairly solid. The first thing you GOTTA do for racing is the FOC (forward only conversion). This removes a lot of weight from the truck.  It also removes a lot of rotating mass, which will help the engine spool up faster. When you do the FOC, carefully check to make sure all the gears line up perfectly. My FOC kit came with instructions that WERE NOT correct. See how to do a correct FOC install here.

The only thing you really gotta do for the tranny is check it once in a while. Tranny bearings will wear out. When that happens, something will probably break.

NOTE: When you take the tranny out and apart, keep track of all small pieces, they get lost easy. Be sure and use plenty of medium loctite when re-assembling the CV joints. Use something like white lithium grease to coat gears. Check all the bearings while you're in there to make sure they are smooth and tight.

See the screw below circled in red? Make sure they are tight! Use threadlocker too.
