2013-2018 RAM 2500/3500 5.7L/6.4L/6.7L Transmission Fluid Thermal Bypass Valve Ram

The thermal bypass paired with the deeper pan, towed 9k from Sacramento to Coos Bay Oregon. I don’t think my transmission ever reached 160. Very very pleased with my purchase from PPE. Cooled my transmission down greatly. And with their upgraded spin on filter, truck is shifting like butter!

HAVEN'T SEEN A DRAMTIC DIP IN TEMPERATURES AND I WAS A DUMMY AND DIDN'T CHECK THE PLUG BEFORE A TEST DRIVE AND LOST NEARLY A GALLON OF FLUID. OOPS MY BAD BUT AT LEAST THE BOTTOM OF MY SUBURBAN WON'T RUST FOR A WHILE

My 2017 Silverado z71 was noticed to be running warm in the 180s even on casual evening grocery runs. Swapped this out in the driveway while dinner was cooking and took it out for a night cruise later on. Stayed around 135-138 with a casual 1 hour drive averaging 45 mph and alot of stop and go. Got up to 145 ish after some red light pulls but never went higher.
Can’t say enough about PPE for designing this solution to the Gm failure.

my first 6L80 trans failed at 64,000 miles with light use, the dealer gave me a new one, I lost confidence in this GM transmission, I installed your thermal bypass valve and it now runs up to 50 degrees cooler, thanks.

Really nice part. Good quality, no issues so far. Does what it says and keeps my trans temp down around 160 even in Texas heat.
