Thread: Trans cooler

Hi all i got a soft dash classic thats got a bit warm lately only when towing think its coming from the transmisson oil ,needs a service i think anyway has anyone modifyed the cooler pipes away from exhaust and maybe take the trans oil away from the radiator ,dose it have to go through the radiator I will be getting the rad serviced as well just to make sure and anything else i can change while i am there .Need to fix or wife says it got to go .

When towing the ZF can get mighty hot, especially with trailer mass above 2 tonne. The viscous coupling also transfers additional heat into the box through the housings.

I have an engine oil cooler which I doubled the capacity and the next step is (was) to double the capacity of the OEM external cooler. Its a lot easier to keep fluid cooler than to get the temp down when its already hot.

IMHO a transssion cooler in the radiator adds extra heat to the engine and lowers the cooling capacity of the transmission element.

There are a lot of generic towing cooler kits out there for exactly this problem.
