* Transmissions built after mid 1976, to serial U-8959 (or higher) with caged needle bearings.
* New design drive slots include lead in ramps for quicker, more positive shifting (same as stock 3rd and 4th gears).
* With Andrews 4 speed gears, transmissions last longer, shift faster, and just plain run better.
