The are 5speed autos that will bolt right up,(to the engine at least) but finding/making a computer to controll it properly is the hard part...
Yep, my mechanic fitted up a 4L60E when I had my tranny replaced, but it was gonna be another 900 bucks to upgrade to a new one. The insurance company refused and said they wouldn't warranty if I did that. I am still out 2K from that work, the company went tits up about two weeks ago. No money to me, but the Pennsylvania Attorney General is filing a class action against them and said I could come away with more than I paid, and the car dealership is refunding the full warranty purchase price. So, at least I get some back, but that just means I could have done the 4L60E swap...
