Transmission Fluid Thermal Bypass Valve
Say goodbye to transmission overheating and add another measure of protection with this easy-to-install billet aluminum PPE Transmission Fluid Thermal Bypass Valve.
The factory thermal bypass valve has an integrated thermostat that cuts off/limits flow even when it fully opens. Restricted flow often results in high operating temperatures and even overheating, which can cause permanent damage to transmission components. The PPE TBV eliminates the extremely restrictive factory thermostat, providing uninterrupted, unrestricted flow to the transmission cooler at all times.
For further protection, a service plug with a built-in neodymium magnet is integrated to the PPE bypass valve. This powerful plug captures ferrous debris before they make their way to the transmission cooler, preventing the cooler from being clogged up. For servicing, simply remove the plug and wipe it clean.
Service Plug Part Number 138051005
Fitment Note: Not compatible with 2025-2026 RAM 6.7L Cummins

Great product lowered my tranny temps fairly straight forward to install. The hardest part was topping off the transmission fluid after the swap out. I burnt my fill bottle from the catalytic converter, had to buy another quart.
Make sure you have the tools before you start, you will need to hold the parts to keep them from twisting the cooler lines.

Simple install, quality is excellent.

Cooled off my transmission temperature. I do wish there were torque specs on the bolts to replace so I could get it right. Had a small leak and then tightened it down a bit more and stopped it. Went from 230 to 140. Good product

It appears after installing about two weeks ago it has reduced my transmission temperature. Just loaded my Four Wheel Hawk slide-in into my 2020 Ram 2500 6.4 L Hemi and left Phoenix for Prescott to have some brackets installed at Mule Outfitters. The temperature remained 10 degrees below previous temperature while maintaining 75 miles per hour during my climd out of the valley. Happy with my purchase

Great product

I installed the PPE transmission bypass valve on my Ram, and it’s one of the best upgrades I’ve made. Before, towing in hot Central California weather would push transmission temps higher than I liked. With the PPE bypass, temps now stay consistently low — cruising at freeway speeds I’m around 138°F, and even climbing grades in 106°F ambient, I never saw above 145°F. This valve eliminates the factory restriction and allows full‑time cooler flow. That means smoother operation, longer fluid life, and peace of mind knowing my transmission isn’t cooking itself while towing. Installation was straightforward, and the build quality is excellent. For anyone who tows or drives in hot conditions, this bypass is a must‑have. PPE nailed it with this product — it delivers exactly what it promises and keeps my truck ready for the long haul.

it does the job keeping trans cooler and an easy install in minutes. you gotta get one of these.

Works great transmission temp runs 140° and takes a while to get there, down from 170° constantly

Install took perhaps 15 minutes and was done in conjunction with the deeper pan. Prior to installation, my transmission temperature averaged 167F and now it’s 24-30 degrees cooler. Ambient temperature was 95F and after a hour of highway driving, the highest temperature registered was 143F. Very satisfied with my purchase and decision to swap out the factory’s restrictive valve.

Putting the valve bypass on is a must when switching to a bigger transmission pan. The transmission runs way cooler now.

Nice chunk of aluminum that is machined perfectly and works perfectly

Do yourself a favor and just purchase this item. It is soooo simple and could save your transmission and wallet! Installation was a breeze, and other than needing a stubby 20mm wrench, no special tools or procedures were needed. I installed the magnetic inspection plug in the 6 o'clock position in order to drain more fluid when doing fluid changes. After looking at the removed factory piece the differences were dramatic. Stupid thermostatic valve is gone, and the PPE passages were larger internally. My transmission now stays at a more even and cooler temperature.

This Transmission Fluid Thermal Bypass Valve solved my high temp problem, on my 21 ram 3500 6.7. before purchasing this part i spoke with the staff and they helped answer all of my questions. Install was quick and simple, will be installing this on my fathers in-laws 6.7 to prevent future failure!!
B
Two great products. Everything works perfectly.
D
WOW! What an amazing product. I plan on doing a full service to my transmission this weekend and I'm super excited to install this piece. The machining is so precise and clean, you can really tell a lot of thought and R&D was put into this. I'm in South Florida and it is HOT down here. I am excited to see what kind of temperature differenced I can get.

my 3500 srw cclb with ppe pan and 4 quart extra cap ran 165 degree with the bypass installed 140 max i could get it . no one tell you true number temps that i could find but here they are . i have diff cover pan and bypass my mpg went up from 23 to 24 hwy
