I just removed my trans to replace it with another one and noticed the bolts holes at the top of the housing are different on both trans's.
One has the housing sort of round with a bolt hole at the very top. The other tran's housing is flat on top with two bolts about 6" to 8" apart.
The old one was suppose to be a TH350, and when I bough the new one I was suppose to be buying a TH350. Help me figure out what I have!
