I've been running my Pro-Build Street-Strip transmission for about 4 months now. I have a corvette torque converter, I added a trans temp gauge, a high efficiency radiator and a dual circuit cooler. (4 pass transmission, 2 pass oil)

Anyway, the gauge reads 210*F when I am driving it within town. Never goes higher. The gauge is hooked up on the line that comes out of the transmission into the first factory cooler. It then runs through the aftermarket unit and back into the transmission.

Is this ok? I want to make 100% sure.

 

I ued to have the same trouble with my tranny...its a level2 bowtie od 700r4. The factory cooler plumbing that it came with can't cool for sh*t, mine was at 220-225* around town. Then I got a dual circiut cooler with a 900cfm fan that comes on at 170* and I ran the tranny directly into the new cooler bypassing all that factory waste of time stuff and I'll drive all day, manual shift it and all it doesn't pass 180* under any condition. So you might wanna do some re-plumbing.
