Hey guys and gals I've got a problem well a big problem to be exact , 1995 Dodge Ram 2500
Not the original owner 250000 miles , just got the tranny flushed and now it over heats I've pulled many heavy loads with this pickup and never never never over heated sat right on 190 , go and get the tranny flushed last week and pulled a little camper trailer over the weekend and the thing over heats as soon as I go up a small incline , I've serched the Web and yet to find anything about this problem, so I thought I'd come here and ask and see what you had to say , now it's got new fluids all around including atifreeze , I did all of those the week before, but what stumps me is , I hauled trailers the day before and never over heated and go on the next morning and had a tranny flush at a well respected shop and that afternoon pulling a much much lighter load it starts to over heat ,

 

First thing that comes to mind is a boost leak, if they somehow disturbed an intercooler boot or clamp. What else is going on with the truck? Power, smoke, modifications, etc

 

Did the way it drives change? like needing more rpm than before, needing more pedal to move etc?
Any change in the sound of the engine and drivetrain?
