Completely rebuilt high performance/heavy duty short shaft turbo 400 that fits Buick, Olds, and Pontiac. This is a 1969 Buick Riviera code BT case rebuilt to high perf spec. It has a five friction disc forward clutch pack, an early style smooth race direct drum fitted with 6 friction disc direct clutch pack as well as a BW 34 element sprag, an Alto 4 disc intermediate clutch pack, early style (stronger) aluminum pistons in all 3 clutch packs, new HD low/rev and intermediate bands, new low roller sprag, and all new seals, thrust washers, and bushings. Valve body and plate were modified for firm solid shifts (not neck breaking) and case/center support/direct drum were modified for dual feed direct apply. Trans will handle pretty much anything you can throw at it. Has approx 800 miles since built and works perfectly. NO converter included. $1200.00 Email through CL or call Rick at 8one5-six53-three7three3 with any questions. Thanks.
