1976 GMC Truck V8 Four Wheel Drive Automatic
In my '76 GMC K15 I am replacing the broke NP203
T-Case. It is currently mated to a TH350 auto trans.
I found a working NP203 mated to a TH400. My
question is will it be a straight across swap or is there
a difference between the two trannies that needs to
be addressed?
