I was towing my camper this weekend. She had to work quite hard due to strong head winds on the freeway. I traveled about 100 miles till I got off the freeway. Once off a short while I let off the gas while climbing a hill cause someone was trying to pass me. When I applied the gas there was like a vibrating/shimming noise. I let off the gas and reapplied it and she was fine. I thought maybe she was between gears. Then for the trip home everything was fine till I got into town and was slowing down for a red light. I didn't have to come to a complete stop but when I applied the gas she did the same thing at 2 seperate times. As soon as I hear the noise I let of the gas and then reapply it she is fine. There is no burning smell or anything? What is going on? Also when ever I tow I also have the OD off even on the freeway.

Hi there,

Thank you for the donation.

This may be a bit of slippage due to over heating, often factory trans coolers are not very good and larger after market coolers work far better, get the trans serviced and have the larger cooler installed.

I have been towing with this truck since I bought it new and never had this problem. What causes it to suddenly start overheating?

Hi there'

We don't want to jump the gun here as I only suggest this as a possibility drawing on previous experience, this may not be your primary problem, heavy towing with only having small factory coolers has been a concern in the past, I would suggest as a starting point get the trans serviced by a trans specialist and get as report, I do recommend having a larger oil cooler fitted as a precaution, as transmissions wear with age, you need this added protection against possible over heating issues, sorry if I did not make my self clear in the first post.

I am gonna service it this weekend and give that a shot. I have been talking with my dad and thinking of adding an extra cooler. Hopefully that will do the job. My previous camper was about 1500 lbs. Heavier. I was just shocked this happening with my new one that is lighter. Just paid the truck off and don't want to have to upgrade just yet. Thanks for your help and if I have more questions I will let you know. Thanks again, Michele
