how would one tell a th375 over a th350?
There're 2 TH375 Trans, A & B.
375B is the HD 350, has TH350 Pan shape & Output Shaft, Cable Detent.
375A is a Medium duty TH400, Has TH400 shaped Pan & TH350 27-spline Output Shaft, 9" Tail, Electric Detent.
On the underside of the trans, right where the tail housing bolts up, the letters "TH-375" can usually be found cast into the trans housing. The 375B/HD350 may also have this cast in.
Some Info >> look in ID & Comparison links.
