I have a 2011 Mega Dually 4wd with 180,000 miles on the stock tranny. Truck has been deleted and tuned since 5k miles, first with mini-max then EFI live ever since. Have about 100k miles towing 18k lb. 5th wheel. Just stated to get tranny temps climbing when in slow and go traffic. Once at highway speeds the temps are perfect, but stop and go they will climb up to as high as 230 deg. Once back on the highway they will drop right back down to the 170-180 range. Coolant temp stays right at 190-195 with a 190 stat.
Thoughts on what the issue could be and also what kind of recommendations for Phoenix area trusted tranny shops or trusted tranny shops in general?
Thanks
