Im going elec. and 89 to present the 98 up models are best and of course it will need to be 2wd. You will need a dipstick, new slip yoke, converter, adapter harness, tranny crossmember and tune.

The only cars that ever had a 4l80e were Jaguars and Rolls Royce. Totally unique bell housings as you can imagine.

It probably would not do you any good unless you are running a Jag or Rolls motor.

The truck and van kind of cars are the ones you're looking for as donors...look for 2 wheel drive trucks or vans like with 6.0 liter (LQ4) engines...such as 2500HD's. Silverado SS is a 60E I think...so ignore that one, just look for regular old work trucks with the 6.0...they're everywhere.

You'll need an LS1/4l80e converter or flywheel, speartech wiring harness, BMR 4l80e crossmember, flexible dipstick, and HPTuners to make you a custom operating system to run the thing with the stock computer (or the TCI transmission controller).

There are many choices for converters, controllers ETC. TCI and fast buy from PCS. There is quite a bit of information out there to make this all work.
