So I was driving down the highway when seemingly out of the blue my '05 MDX started revving up to 7000 rpm's and not actually going any where. I got of the road and had it towed to my mechanic. They are telling me that I had a failure in the radiator which somehow caused all my tranny fluid to end up in my radiator with the coolant, and because of this my tranny burned up. I'm being quoted $6000 to replace the tranny, radiator and all associated hoses and parts. I'm not a car guy but any means so I could be spewing nonsense for all I know, but I was looking for some outside opinions on how to go about handling this situation. 6000 is a lot to pay for a car I still owe 11,000 on even tho the car is probably only worth around 7000.
