“While driving, I suddenly started getting transmission slippage . Engine would rev up, but no power to the wheels. I was able to pull off the road. There was a strawberry milkshake colored fluid coming out of my radiator overflow container. Turns out the that transmission cooler inside the radiator broke loose and allowed engine coolant to mix with the transmission fluid. Apparently it's not an unknown problem. I'm lucky that I was in a rural residential area and not on the interstate.”

This issue will cause engine failure that could result in wrecks due to the violent nature of this failure. This would cause immediate panic to my pregnant wife and soon to be newborn baby girl.

After a couple of seconds the warning lights went off and the noise went away. When I started to drive it surged a couple of times and then ran normal.
