My stock 4L80E with 270,000 miles on it in a 93 turbo diesel 4x4 dually behind a turbo diesel will withstand all the abuse you can throw at it.

For about 2 grand you could have a 4L80E done and running in the car that will last as long as the car is running, you can run slicks if you want to, and never worry about it coming apart.

Myself I like all the safety margin I can get for the least amount of money expended. I also like to start with a platform that was engineered for abuse from the beginning, 440 lb ft of torque in stock form.



Notice 2007 post, where Jake is recommending a 4L80E over a 200 because the 200, even with billet parts is getting sketchy at between 550-660 HP.

Depends on what you want to spend, and how much HP/TQ you want it to withstand reliably. Are you ever going to run slicks at a dragstrip with the car? The car owner/OP is in control of the decision.

Frankly, I think 2 grand is about $500.00-700.00 too high unless you are factoring in everything including adaptor plate, crossmember, cutting the driveshaft, etc. But then again, I guess it all depends on location, connections, etc.
