Th400 trans problems!!

SCOTT SST2871 · 11-23-2009, 11:43 AM

Anyone have suggestions on a fix (other that switching to a glide)i cant keep a trans in my car more than 70-80 passes.i've been told its a sprag issue..when it goes bad it wont shift into 2nd gear under power,but you can shift it into 3rd. I have 2 transmissions with 2 different valve body manufacturers and they both do the same thing.its a s/st car ,has about 450 hp,weighs 3025 lbs and the stop goes on and back off in 1st gear
thanks
