Medatronic's Autodyne division has been making rebuild kits for all popular domestic standard transmissions for over 25 years. Thousands of kits have been sold worldwide. All rebuild kits contain what are called "wearable" parts. Included are main bearings, synchro rings, gaskets, seals, countershaft, and small parts. Small parts include needle bearings, snap rings, tailshaft bushing, thrust washers, shims, roll pins, shift keys or "dogs", and springs. Many people copy our kits, but few take the time to make sure only OEM approved parts are packaged in each kit. Some manufacturers don't even include a countershaft! All kit components meet or exceed OEM specs. If you are not satified in any way we have a full refund policy. Original vendors who might have made these parts for GM, Ford or Chrysler, were tracked down and contracted to reproduce and improve our kits parts. Below is a list of our most popular kits.
