My trans has run on the warmer side of normal since I've owned it, but never an issue. We recently bought a travel trailer and while towing in the Texas hill country (not very big hills) w/ ambient temps around 80*, my trans hit 200-205*. This prompted action. I ordered a Tru-cool trans cooler from www.dieselsite.com/. I installed it along with a Magnafine filter today. The install was VERY simple. It took less than an hour with my 3 year old helper assisting. It is mounted to the upright supports behind the grill shell.
I went with this cooler for cost reasons over the 6.0 cooler. But now I'm really happy as the install on a 6.0 cooler would have been far more involved. I think this will solve the temp issue. We'll see in a couple of weeks when we head to Arkansas for a trip while towing the TT. I will caution to pay attention to the FLOW direction on the Magnafine filter. I was distracted by the wife and helper and put it in backwards and caught it while checking for leaks post test drive.
