Thread: Transmission fluid leaking into radiator.

I have just discovered that the transmission fluid is leaking into the radiator. So my first thought is to replace the radiator and flush out the transmission fluid. But i am not sure if the coolent has enetered the transmisson. I am wondering if anyone has any suggestions what i am up against. Thanks

Also, Is there a Transmission cooler on the car or is it with the radiator...I am getting confused.

You need a new radiator. Yes there is a built in trans cooler in the radiator. Sometimes they rupture. The bigger concern is there is no coolant in the trans fluid.

Replace the radiator, flush the coolant out, replace with new, drop the pan on the transmission, put in new filter and new fluid. Then have the trans flushed as soon as possible afterwards.

I could not agree more, do exactly this.

This happened on my camaro.
