I am swaping from 4L60E, this is the third on gone bad about $3,000 wasted so I'm going to the 700r4 and the 4L60E has a diff. connecter so is there a way to get the right connecter and about how much would it be!?!

 

Well all the hard parts are the same so you might not gain much. Probably use a 93 F body harness, but I would say those would be hard to find used. Your speed sensor will plug right up with your current harness. Lockup might be harder. Probably be better to just use the B&M lockup control for $160.

 

the harness only controls lock-up and tells the PCM when you car is in 4th.

No reason to go to a 700R4. if your guys can't build a 4L60E I can't see them doing much better on a 700R4!

We have our 4L60Es running 9s and 10s so yeah I am pretty sure
