Would It be worth putting one that came off a 2.9L 4X4 onto my 4.0L? I found one on craigslist for a few hundred bucks. My mechanic says he wouldnt waste 1200$ on a new A4LD because my 4.0L engine could blow at any time, they suposedly have head problems and mine leaks a tiny bit of coolant into the #1 cylinder.

The check ball configuration is different. Are you going to use a rebuilt torque converter? What year is this transmission from, and what is the year of your vehicle? How mnay miles does it have?

mine Is a 1990, the one on craigslist is a 1989, supposedly had 70000 on the vehicle it came out of but the dude that got the truck for the motor said it was hard miles, that the guy couldnt keep it out of the ditches aparently, I dont know what to do about a torque converter
