So im running a TCI streetfighter C4 in my 76 mach 1 behind my 302. As i was driving down the freeway and slowed to get off at my exit, the tranny suddenly down shifted into 2nd. After that i have not been able to get my car back into 3rd gear. I can manually shift it between 1st and 2nd, but if i start driving in "drive", the tranny just stays in first. It wont shift at all in Drive. The tranny only has about 500miles on it and this is the second TCI tranny to do this exact thing.

Im running two tranny coolers, TCI's tranny fluid, fluid has good color, and have all my hookups done to spec. Does anyone have any ideas?

From talking around, people are telling me that i have a valve body issue. I want to go to a full manual valve body anyways and have heard that those cure alot of shifting problems. Any help would be great.
