Improve transmission cooling and reliability with the PPE 68RFE Transmission Thermostat Bypass Valve Block. Designed to replace the restrictive factory thermal bypass valve, this billet aluminium upgrade provides unrestricted transmission fluid flow to the transmission cooler, helping reduce operating temperatures during towing, touring and demanding Australian conditions.

 

The PPE 68RFE Transmission Thermostat Bypass Valve Block replaces the factory thermal bypass valve found on 2019+ Ram 2500 and 3500 models.

The OEM valve contains restrictive internal passages and relies on a mechanical thermostat to control transmission fluid flow to the cooler. If the factory valve sticks or becomes restricted, coolant flow through the transmission cooler can be reduced, contributing to elevated transmission temperatures and accelerated transmission wear under heavy loads.

The PPE billet aluminium replacement removes these restrictions, providing continuous transmission fluid flow through the transmission cooler for improved cooling performance and greater thermal stability.

For additional protection, PPE incorporates a removable Neodymium magnetic service plug, designed to capture ferrous wear particles circulating through the transmission system.

Whether your Ram is used for towing, touring, heavy work or performance driving, this simple upgrade helps improve transmission cooling efficiency and long-term reliability.

Key Features:

  • CNC-machined billet aluminium construction.
  • Durable black anodised finish.
  • Eliminates restrictive factory thermal bypass valve.
  • Improves transmission fluid flow to the cooler.
  • Helps reduce transmission operating temperatures.
  • Neodymium magnetic service plug captures ferrous debris.
  • Direct bolt-on replacement.
  • Suitable for towing, touring and heavy-duty applications.
  • Limited lifetime manufacturer warranty.

Why Upgrade?

Transmission heat is one of the leading causes of automatic transmission wear.

Replacing the factory thermal bypass valve helps:

  • Improve transmission cooler flow.
  • Reduce transmission operating temperatures.
  • Increase cooling consistency under heavy loads.
  • Improve towing performance.
  • Enhance long-term transmission reliability.
  • Reduce the risk of overheating caused by a sticking factory valve.

Ideal for:

  • Caravan towing.
  • Heavy towing.
  • Touring.
  • Performance tuned vehicles.
  • Commercial use.
  • Hot Australian climates.

Why We Recommend It:

At Garage76, we regularly recommend transmission cooling upgrades for customers who tow caravans, carry heavy loads or operate in high ambient temperatures.

The PPE Thermostat Bypass Valve Block is a simple yet effective reliability upgrade that improves transmission cooler flow while eliminating one of the more restrictive components in the factory cooling circuit. Combined with the PPE Deep Transmission Pan, it forms an excellent transmission reliability package for the 68RFE.

DIESEL TUNING STAGES

WE OFFER THREE STAGES OF DIESEL PERFORMANCE PACKAGES

From a safe and reliable tune of your OEM ECU through to wild diesel performance upgrades, we've got 20+ years of diesel tuning under our belts and can tailor a package to suit your performance or touring needs.

STAGE ONE
(10-30% INCREASE*)

Our Stage One kits (vehicle depending) will always include an ECU remap and a tune on our in-house dyno. 
No two vehicles are the same and every diesel performance package we book spends time on our dyno.
  • G76 Custom ECU Remap

STAGE TWO
(30-50% INCREASE*)

Once you are looking to go beyond the performance of our basic Stage 1 Package, you will reach the limitations of your factory turbocharger. At this point a turbocharger upgrade will be required, along with appropriate upgrades to the exhaust, air intake system and intercooler. With these upgraded items we are able to squeeze more performance than a stock setup will ever provide.
  • G76 Custom ECU Remap

  • Upgraded Exhaust

  • Upgraded Snorkel & Airbox

  • Upgraded Turbocharger

  • Intercooler Upgrades Or Intercooler Fans

STAGE THREE
(50+% INCREASE*)

Looking for maximum GRUNT without compromising factory reliability? Our Stage Three Package is for you! This package will give you the ultimate in diesel performance, with massive gains available in power and torque. 
The main difference between our Stage Two and our Stage Three Package is the addition of high flow fuel injectors. In a diesel engine, more fuel = more power, provided you have the air to burn it! We also only have a small window of crankshaft rotation available to inject the fuel. High flow injectors allow us to increase the amount of fuel delivered to the engine during this window, resulting in huge gains in power and torque.
  • G76 Custom ECU Remap

  • Upgraded Exhaust

  • Upgraded Snorkel & Airbox

  • Upgraded Turbocharger

  • Intercooler Upgrades Or Intercooler Fans

  • High Flow Injectors

  • Upgraded Fuel Pumps

*power and torque numbers will differ between vehicle models and final diesel performance packages and tunes. Our increase numbers should be used as a guide only. Different vehicle makes will have variations in the packages we offer, not all packages come with intake cleans.
