I recently had my transmission overhauled at a local transmission shop. To make a long story short, when I got it back I drove 50 or so mi. and a line busted and emptied the tranny of fluid. When I got it back again my cruise worked for about 10 miles and a week later the coolant lines for the transmission broke inside the radiator which has now mixed with engine coolant both in the motor and tranny. Does anyone have any idea what is going on here?

 

Why did you have it overhauled in the first place? The H3 has a built in tranny cooler in the radiator so when the cooler lines go n the tranny it will mix with the engine colorant. S you gotta replace the whole radiator. To avoid this you can get an external tranny cooler.

 

I had it overhauled because it broke. I lost D and 3. I was able to upshift from 1 or 2nd to get it into D. Now that they are rebuilding this again they are installing an external cooler. Is it possible that line pressures have increased dramatically since the rebuild? I mean I have had 1 busted line connector and now a broken tranny cooler inside the radiator.
