Troubleshooting Ford F350 with a Hot Transmission

Question:

I removed the factory cooler replaced it with a Hayden cooler but it didnt help so I installed cooler with a fan on it underneath the truck blows good but it didnt help my problem. I am pulling a tag a long camper wgt. about 8500 lbs. most of the time it runs from 175 to 200 depending on the terrain but it will get to 230 in mountains I have an Edge programer that has a guage when gets to 230 factory guage starts to move thats when I stop what else can I do to fix my problem ?

Helpful Expert Reply:

With two transmission coolers as well as an Edge programmer your transmission should definitely not be running hot, unless your trailer is grossly overloaded or you programmed the shift points inaccurately on your programmer. The first thing I would do is make sure you are staying within the weight limit of your truck. Then I would reset the shift points on the Edge Programmer. If that fails you might have your transmission checked out by a professional mechanic.
