CAN ATF LEAK INTO THE COOLING SYSTEM ON A V6

2003 Honda Accord • 16,000 miles

I have a 2003 accord that has brown colored coolant, and having tranny slipping. Transmission was very low on fluid. Replaced fluid. Flushed out cooling system. Car drove very well for about 70 miles. No transmission slipping. Then started slipping again. Looked into engine compartment and more brown being forced out of the coolant resevore and tranny was very low on fluid again.

The transmission cooler runs through the radiator. There must be an internal leak there. This needs to be repaired ASAP because it will take out the trans.

Check that for me. If I am correct, the radiator will need replaced.


This model does not have hoses to the radiator. There is a cooler/warmer that is attached to top of transmission. That unit should be faulty and requires replacement.
