So I am 99% sure my tranny cooler in the radiator gave out. I had this issue once on my 88 S-10. My tranny fluid is going up, it is burnt, has bubbles, and it won't shift at WOT. Otherwise is fine. Is there any other way for the fluids to mix? Is this a common problem? We bought the car not too long ago and so I don't know how long it has been like this. Anyway figured I would ask before I blow 150 bucks as money is super tight right now.
