1974 Chevy K5 Blazer Th400 Transmission

Prev Next
Orange County Transmissions had just finished giving a TH400 tranny a complete B&M parts overhaul while adding in a few of its own tricks for this truck (Turbo 400 Revival, p. 68). I hauled it up to Santa Rosa, California, to the Fabworx shop where Arrington added the new B&M torque converter and flexplate. We made sure to swap the output shaft because we were going from an NP205 output to an NP203 output, as this K5 was receiving the Off Road Design NP203/NP205 doubler kit.
