I have 2 6r80's in my shop. One to go in my 71 Ranchero CJ with 429, The other going in my 428 63 Galaxie.
I took some measurements and can install it in the 71 without cutting the floorboards. I haven't got the Galaxie in the shop yet but it looks like it will go in with no clearance problems but will be close.
Cost are reasonable and a lot cheaper then a Tko 600 that I was going to use in both cars.
So far the tranny's cost me 460.00 each with less then 60,000 miles on them.
I haven't ordered the controller yet but was talking to the seller today and he said $1250.
The adapter kit is $950.00.
If you are using
Here are pictures of a C-6 next to the 6r80 for comparsion.
the cable speedo drive Dakota Digital makes a adapter ECD-100. I haven't had a chance to see what they cost yet.
I have friends running stock 6r80's in the mustange with twin turbos with no mods to the tran's so I know they are a great tran's.
