42RH / A500 question
The V6 is likely 904 based AKA A500
The V8 is likely 727 based AKA A518
Easy to tell, look at the pan, look at the passenger side. If the pan has a big "bump" along the pass side it's a 727/ 518
On far left is 518, middle is older 727, and A500/ 42R is at right. Notice the bump in the side on the larger transmissions
.............and that translates directly to the two pan gaskets below
Also make sure your transmission core is actually hydraulic and not electronic. Hydraulic has the usual backup/ park switch, and another 3 terminal connector for the lockup and OD. The electronic ones have a multi pin connector for the computer, I forget, 6--8 pins
