Transmission oil cooler recommendations

**deeze12** · 06-14-2021, 07:34 AM

I have a 07 Chevy Tahoe and recently had the transmission rebuilt. I decided to drive to Las Vegas with my family and as we were passing through Baker, Ca the transmission temperature started climbing to about 207° and engine was sitting at 210°. Now I know that typically trans fluid should stay 20° below eng temp, and ai wasn't pushing the vehicle or towing, but I have been thinking maybe it's a good time to install a transmission oil cooler. Any thoughts/recommendations? 07 5.3L V8 with the 4 spd transmission, 2wd.

207*F trans temp is nothing to worry about. But a little cooler would be nice.

Any recommendations on trans coolers? I would like the most efficient with the most affordable cost, one that won't break the bank, but will help cool the fluid down.

Thanks in advance.

So an update-I installed a Hayden Automotive 679 Rapid-Cool Plate and Fin Transmission Cooler, Black, 11 Inch. We towed our 28 ft travel trailer up to Oregon and back in about 5 days and all the time I was monitoring my trans temp. Up into Grants Pass, it got about 240 degrees F but then would cool to about 180-190 going downhill or flat areas. All in all, I am happy with the cooler, although I may fabricate a mounting bracket so that it has more airflow around it rather than being strapped to the radiator with the little zip ties that came with the kit.
