Thanks Dave

Swapping to the 4r100 is going to be a very big deal! First of all,,the one you have is not for a 4X4.
I put one in my truck and it was a pain in the azz! And I took out the T case long ago.
I had to change the trany wire-harness,my exhaust,had to buy a new cross member,shorten the driveshaft,buy a L computer,new flywheel for 4r100,.
Got it in and it wouldn't change gears automatically. So you need the dash wire-harness.
We repined both ends ( computer & trany harness) And ran the 3 wires separately that were missing in the dash harness.
It was definitely a major pain and expense. But I had no choice.(went through 3 built 4r70s in 3 years!)
