Trans temps go up 30 degrees after tire size change?

I went from 35's to 37's with factory gears, now my trans temps when crawling in traffic on a 101 degree day have gone from 160-190, even got near 200 until I got on highway, then they dropped back down. Anything to worry about? I know the 20% rule, but seems like a lot. If I add a cooler any recomendations? Should I go ahead and install that tugger kit also?

This is normal with the larger tires, as will be higher EGT's as well. A tugger or valve body wouldn't hurt and if you are going to tow or temps regularly get up that high an additional cooler would really help keep control of the temps. You could also re-gear though and get back all that and some power...

That would go nice with that 6.0 intercooler I've got in the garage

You do know they work better if you actually put them in the truck, right?

I'm a fan of the transgo, but you need to figure out what the TS chip is doing to your line pressures now. If you get the Transgo, stay away from Oregon Performance Transmission. They're a bunch (or at least one) of idiots.

I'm in Dallas, so unless I put it in myself it'll go to 2 brothers transmissions. Yep, I know things work actually installed on the truck, just never got the right boots for the intercooler.

I wonder how many of the discarded 7.3 transmission coolers it would take to get the cooling of a 6.0. I added a 31 Row cooler, but have the stock one on a shelf.

If it were copper, I know some guys that could use it to make some ummm.... corn fuel, yeah, that's it. Corn squeezins for the truck.

I'm 15 miles North of Hillsboro and have installed a Transgo in 2 different 4R100 trucks. From what I've read of your posts, you would have absolutely no problem installing the kit, but if you're gun shy getting into the tranny, we can figure out a way to hook up and I'll help you do it. (I can reprogram your speedo too with AE)

Seems like Clay at Riffraff can get you the right boots for your IC swap.

So that's the problem.My new 6.0 cooler and gauge have been on the shelf for a couple years and think the truck is somewhere in the back yard.Guess I should dig'm out and put them in one stack.I mean put them together
