Hot Transmission

I took my Sunline to the family reunion in Milford, PA. Poconos area with winding mountain hills.

Had to stop twice to let the tranny cool as we crossed the Delaware. Idiot light came on and we just took a 1/2 hour break.

This was my first long haul, about 3.5 hours. Have a small cooler in the truck already but will strap a larger one on this week.

My equalizer hitch setup is a joy as no sway present, but I was gripping the steering wheel tight as I climbed the hills. On the ride home I took two breaks and let things cool down, It worked.

But this week I will drop in a bigger cooler, change the filter/fluid and get a temp gauge installed.

All in all we had a great trip, this is fun!

If your truck has an overdrive gear, the tranny may overheat when climbing hills if you leave it in overdrive.

My '98 Dodge Ram 1500 had overdrive, and it was stated right in the manual's towing section that the overheating may occur, and that shutting off the OD will generally eliminate the problem.

I followed the instructions and never encountered an over heated tranny in the 9 years I had the truck. We travelled extensively in PA, the Adirondacks, and much of Vermont and New Hampshire.

Hi Steve,

Yes I did have the OD turned off. Did you have a trans cooler on that truck? I will be OK once I drop a larger cooler in it.

Mine had the factory HD equipment option which is the same as the towing option less the receiver and wiring. That consisted of bigger battery, bigger alternator, big tranny cooler, and a big oil cooler.

Just back from Pep Boys

I got the Hayden Rapid Cool for towing up to 10k lbs. Largest one they had.

Will strap it in tonight.

After talking to the folks at Hayden, I returned the cooler and opted for a GCVW 26k model I found at the local trans shop.

Got the truck back yesterday and all looks/smells new and fresh.

Seems like you never know what the long term affect is of the hot trans oil. Hoping seals hold up. Will let you know over the next 10k miles.
