Joe,you have the exact same transmission that i have.The factory s-10 owners manual calls for dextron atf fluid.The dealerships also say to use atf fluid.There are several shop manuals that say use atf fluid.The two t-5 transmissions that i pulled from the salvage yard had atf in them.I'm running the atf with no problems.

What type of fluid was in the transmission when you got it ? I would call around to some dealerships and transmission shops before you drain it.See if they know what is wrong with it.

Let us know what you find out.
