Not a lot of good feedback from folks who've gotten engines and trannies from places such as AutoZone, Advance Auto, and the like. As mentioned, see if you can snag one from a junkyard. Look for one that isn't leaking. You may end up with a bad one, but at the cost of what a reman unit is going to be you could buy 4 junkyard trannies. I'd say odds are you'll come across a good one by that time.

If possible, look for one that might have spent it's life being towed behind an RV (Good Sam Club stickers, tow hitch up front, etc). If an elderly couple drove it around it may not have been abused as much.

BTW...the data plate which should show your tranny number should be in the engine bay, right about at the top/middle of the firewall (back-end of the engine bay).
