ok, my gut feeling is the trans is getting alittle warm when pulling the boat, usually gets to 195 205, about 5 miles into the trip and stays there, is this hot for pulling a 21 foot boat in 90 degree weather. if so i want to put a trans cooler in, in a stock L setup the lines go from the trans to the radiator cooler to a small cooler in the front bumper back to the trans, if i do put one on it will be one with a fan from summit, should i bypass one or both of these stock coolers and if i do bypass one whick one...


tks

205 is a little high, but not terrible. I would get an aftermarket cooler and add in in addition ot the 2 already on the truck, add it after the aux cooler (the small one).

Hope this helps,
