I agree water is real bad for transmissions.... but RUST??

It might be.... but I would be surprised - was the trans fluid strawberry milkshake color at anytime? Maybe the previous trans shop dumped rust into it????

This is why I do 99.9% of my own work on my jeeps, too many scammers our there !!!!

I suppose it is also possible that the trans cooler (heat exchanger) in the radiator failed (either currently or sometime in the past) and dumped rusty coolant from an unmaintained cooling system into the trans.

To the OP: make sure to check for this, it would suck to put a new (used) trans in it and just have it fail again from coolant contaminated fluid. It is also important to make sure the cooler and lines are flushed even if they are good, otherwise you're putting whatever crud was in the old fluid into your "new"/rebuilt trans.

I hope I get a refund this year!
