I caught this very early and noticed something in the trans fluid that didn't look right. Took it to the mechanic who knew about this defective radiator cooler and we caught it very early and it didn't ruin my transmission. He flushed it like 4 or five times just to make sure their was no radiator fluid left in the transmission to mess it up. He did say it could eventually suffer early failure because of coolant residuel on clutches.
