Chevy Camaro THM400 Transmission 1973-1975, Super Hydra 400™ Transmission Case by Reid Racing®. The Turbo 400 is the favored 3-speed transmission today for high horsepower applications because of its light weight, minimal drag, and its tolerance of abuse. As rugged as it is, there is one glaring weakness; the internal case "lugs" that retain the center support and pressure plate do not go completely around the inside of the case. At high horsepower levels, the "lugs" closest to the gap become overloaded and they fail. This sets off a chain reaction and all of the remaining "lugs" fail in a zipper-like fashion ending up in a ruined transmission. Reid Racing, Inc. has redesigned the Turbo 400 to correct this problem and has added dozens of features that improve every aspect of the case.
- Full 360° lugs
- Improved billet pressure plate
- Oversize snap ring
- Longer band anchor pins captured by oversize bosses
- Numerous strengthening features address problem areas in the GM case
- Additional dipstick hole on driver's side
- Multiple external pressure taps allow monitoring of circuit pressures
- Accepts all style oil pumps including 8 bolt and vari-pitch designs
- Bellhousing and oil pump threads are heli-coiled
- Pre-machined to fit larger custom planetary gear carriers
