The install is pretty easy. I opted to purchased a replacement crossmember that fit perfectly! Also did a Dakota digital digital to mechanical speedo converter.

A must is these cooler line banjo fittings. That is probably the tightest part of the trans tunnel and the banjo fittings make it possible. I bought these, some stainless 5/16 tubing and a couple AN fittings. I bent them up to come out in the same location as my TH400 cooler lines did from the factory. Cut my factory cooler lines, installed AN fittings and it works perfectly!

Here’s a list of parts I put together before I did my swap:
Transmission
converter
Dipstick
Remote TPS (TCI 377450)
USShift Quick 4 & harness
Trans crossmember (RCAE-4)
Shiftworks brackets
Cooler fittings
Stainless Cooler tubing
Trans fluid
Dakota digital Mechanical speedo converter
Driveshaft

BTW I am selling my USShift controller and TPS because I am switching over to EFI and the Holley system has all the trans controller stuff. PM me if you’re interested.

Sean, thanks for all the great info! I really like the nice job you did with the cooler lines and will steal that idea! I'll PM you.
