Description
The Thermal Bypass Valve is a precision-engineered replacement for the factory thermal bypass valve, eliminating the common issues of leaks and sticking. By ensuring that transmission fluid always circulates through the cooler, it significantly improves cooling efficiency, reduces the risk of overheating, and extends transmission life. CNC-machined from billet aluminum, this upgrade is both durable and corrosion-resistant—ideal for trucks that demand reliability under heavy load, long hauls, or high-temperature conditions.

FAQ
Q: What problem does this bypass valve solve?
A: It eliminates the common leak and sticking issues found in the OEM thermal bypass valve, ensuring consistent transmission fluid flow through the cooler.
Q: How does this improve transmission performance?
A: By guaranteeing that fluid always passes through the cooler, it helps regulate temperatures, prevents overheating, and prolongs transmission life.
Q: Is installation difficult?
A: No. Installation typically takes about 10 minutes and requires only basic hand tools.
Q: Will I lose transmission fluid during installation?
A: Yes, a small amount of fluid may be lost. It is important to top off the transmission with the correct type and amount of fluid after installation.
Q: Does this affect cold-start performance?
A: Yes. Since the bypass function is removed, fluid flows through the cooler even during cold starts. This may cause slower warm-up times and slightly affect shifting in extremely cold climates.
Q: Is this upgrade necessary if my truck is stock?
A: Yes, even stock trucks can benefit. Preventing bypass valve failures improves reliability, especially under heavy towing or hot weather.
Q: Will this fit both 68RFE and Aisin transmissions?
A: Yes, it is compatible with both the 68RFE and Aisin AS69RC used in Dodge Ram diesel trucks.
Q: What material is this valve made of?
A: It is CNC-machined from billet aluminum, offering superior durability and resistance to corrosion compared to OEM parts.
Q: Can this part improve transmission lifespan?
A: Yes. Keeping fluid temperatures lower reduces heat-related wear, helping extend the service life of the transmission.
Q: Is this a permanent fix?
A: Yes. Once installed, this billet bypass valve will not suffer from the leaks or sticking issues common with OEM units.

Frequently Asked Questions
What is a delete tuner?
A delete tuner is a device that reprograms yourtruck's ECM (computer) to turn off emissionssystems like the DPF, EGR, and DEF, allowing yourtruck to run without those components
Can l use a delete tuner withoutphysically removing TheDPF/DEF/EGR parts?
You MUST remove your DPF(Diesel ParticulateFilter), as the filter will clog and stop all exhaust flowwhen shut off. You will no longer need DEF(DieselExhaust Fluid), and you may remove your DEF tankif you wish, or it can sit empty. The EGR may remainas is, but we recommend removing the physicalparts as well.
Is a Delete Tune bad for mytruck's engine?
Quite the opposite. In fact, many customers reportimproved engine life, smoother shifting, and betterfuel economy (typically 3-5 MPG gains) when usinga quality delete tuner.
What's the difference between adelete tuner and a delete tune?
The tuner is the hardware device. The tune is thesoftware file that gets uploaded to your truck's ECM.Your delete tuner includes a delete tune when youpurchase from us.
Do delete tuners void my warranty?
Yes. Any emissions-related modification, includingtuning, can void the manufacturer's warranty. Manycustomers wait until after their warranty expiresbefore deleting.
Do l need a mechanic to install thetuner? How long does installationtake?
Not necessarily. Many of our customers install their delete tuner themselves in under 30 minutes. We include easy-to-follow instructions, and our support team is available if you need help.
Will my truck pass inspection oremissions testing with a deletetuner?
No. Delete tuners disable emissions systems, so your truck will not pass emissions tests in areas where they're required. Some states have exemptions (e.g. heavy-duty or rural-use trucks).
Can l go back to stock afterinstalling a delete tuner?
Yes. However, in most cases you will have to have the ECM flashed at the dealership. If this is a concern, contact our team and we can explain further.
Is the delete tune VlN-locked?
Yes. All delete tunes are VIN specific and will only work on one truck. The tuner (hardware device), may be used on multiple vehicles for diagnostic or monitoring purposes where applicable.
What support do l get with my tuner?
We offer lifetime customer support, step-by-step install guides, and remote help from our tuning team. You're never left hanging, even after the sale.
