So I am going to install the 6.0 cooler and then install a B&M 13'x9' under the truck bed with a fan. Got a reponse back from BTS about my tranny temps as well, and Brian said they are not installing the V10 tranny cooler anymore, rather they are using the 6.0 cooler in its place. Like I said though, if I have to buy a new one, that is part of the game and I usually play by the rules. I have taken two pictures of the chip if anyone is interested in looking at whether it belongs to TS or not. Either way I don't have a problem with buying a new chip, although it would work out great if I could just reuse this chip and have it reprogrammed. I took the chip out today and I don't see the TS emblem on it, but I do see what appears to be a part number on it that says TS-004, so that may be theirs. I bought this chip from Performance Truck Products. Well I am not so sure if this is a TS board or not. Total GCVW of both the truck and trailer is 21.3K

We are going to head out to Yellowstone and Glacier next June and I don't want to have issues while in the mountains. Then maybe the B&M cooler with a dedicated fan. I have also read that I should probably replace the factory radiator for a OWC type as my truck is a 2000 and only has the V10 style radiator that BTS installed. I have been looking into the TC Lockup mod and think that might be a good idea. What I have noticed is that before going up a steep grade I have to of course take it out of OD, then tap the brake pedal to unlock the TC, otherwise I loose power really quick, tranny temps go up, and EGT's going up extremely fast.

But the hours I spent reading on the forums last night, I think the tranny temps my be caused my driving style. I do have the BTS tranny and TC so not too worried about the drive train, just controlling it. When I am not towing, the TS chip is perfect not a problem at all. But from others here on the forum the DP-Tuner chip seems to control the TC a lot better. Well I really hate to give up my TS chip because it is awesome.
