Transmission cooler

[jetmech]

So this transmission cooler is now installed and I'm glad I finally went through with it. My transmission would usually stay in the neighborhood of 180* - 200* (even saw it climb to 230*) and now it stays at about 150* driving through town on a 95* day. Also, it get's down to about 130* on the highway. Just thought I'd share.

through the radiator

I have a larger 34" radiator, royal purple fluid, and a factory trans cooler. Even with all my extra weight, and beating on it today in the 90* heat...I only saw like 152. I have a stock stall, do high stalls really add THAT much more heat?

A real high stall like 3000 will create more heat becuz of the TQ slipping more for higher RPM's. Something like a 2000 not as much. But, adding a cooler with everything stock is recommended. Heat is killer!

I was basically a bone stock 4.8 with a 60e, and in the summer the trans would get up to 220* or so. After the 40k cooler, 120-150* on average. Your larger radiator and that factory cooler must be helping you out quite a bit.

Did you get the cooler with the internal bypass?

I just got the same cooler, but with the thermal bypass. Will be going on next Wed...can't wait.
I don't think the OP needs the one with the thermal bypass as he's not in a cold weather climate.

Same here and No I didn't get the thermal by-pass.....Florida is always way too damn hot

One of the best upgrades to do, for trany longevity IMO
