Can you tune a 68RFE transmission?

68RFE automatic transmission equipped trucks, you have the option to add transmission tuning. One of the major benefits of having such an electronically controlled transmission are that so many factors, such as converter lock up, line pressure, and shift patterns can be controlled electronically.

How much horsepower can a 68RFE handle?

500rwhp
With quality transmission control module (TCM) tuning, the stock 68RFE can support 500rwhp and 1,000 lb-ft or more, but it won’t survive boosted, four-wheel drive launches for very long—and maybe not even once if the Low/Reverse sprag explodes (which is common).

Who Makes 6 speed automatic 68RFE transmission?

In comparison, the Chrysler 68RFE six-speed automatic is a light-duty-pickup transmission that weighs about 260 pounds and isn’t set up to use a PTO. The 68RFE is a well-designed and strong transmission with gear splits suited to the normal load-moving tasks faced by heavy-duty Ram diesel pickups.

Can you bulletproof a Cummins?

Like the 6BT Cummins, the turbochargers bolted to them are hard to kill. In particular, the Holset HX35W found on ’95-’98 12-valve engines is particularly bulletproof. This turbo made less than 20 psi of boost in stock form, but can be subjected to 40 psi on a regular basis and survive without overspeeding.

What is TCM tuning Cummins?

TCM (Transmission Control Module) Tuning that will deliver 2nd Gear Lockup and a modified shift schedule to promote longer transmission life and a firmer shift under engine load so you’re getting more power to the ground. TCM tuning is only available for Rams equipped with the 68RFE transmission, not the Aisen.

Which transmission is better Aisin or 68RFE?

A final benefit to the 68RFE that may be relevant to some consumers is it’s fast shift speed compared to the Aisin. This is because the 68RFE does not necessitate as much of a fuel de-rate during shifts to facilitate a safe and properly timed clutch to clutch transition.

How much line pressure can a stock 68RFE hold?

170 PSI
Line pressure is limited in a stock 68RFE to 170 PSI.

Has the 68RFE been improved?

In 2019 Chrysler made several changes to the 68RFE. These changes included adding an auxiliary valve body, adding a dedicated TCC control solenoid, and changing the TCC regulator valve. Other changes include modifications to the valve body and the channel casting for controlled reverse and underdrive venting.

Is the 68RFE good?

Overview of the 68RFE: Despite all of the impending doom the 68RFE and it’s abysmal valve body bring forth, it is a powerfully reliable transmission after being properly built. But, in stock form, it cannot hold much more than factory power.

How can you tell the difference between a 68RFE and Aisin transmission?

All you have to do is open up the hood: If your yellow dipstick handle is on the right side of your engine (the driver’s side), you’re likely looking at a vehicle with an Aisin transmission. If your dipstick is just to the left of your engine, you’re most likely dealing with the 68RFE.

What is the P pump for Cummins?

This injection pump, often called a “P-pump,” is the Holley Four-barrel carburetor of the diesel world. The P7100 pump has been around forever, is practically bulletproof, and is very tunable for high performance. The Dodge Cummins engine has used four different Bosch-sourced injection pumps over the last 20 years.

What is a TCM tune?

TCM tuning is the modification of the programming calibration of a vehicle’s transmission control module (TCM), which handles the strategy, timing, and schedule for switching between gears. Tuning, in this use, is an aftermarket adjustment to the calibrations that are programmed by the factory.

Is the 68RFE reliable?

How many gears does a 68RFE have?

The first improvement Chrysler wanted to make over the Torqueflite platform was, obviously, the amount of forward gear. For the 68RFE transmission, Chrysler opted to change to a six-speed unit. The additional gears allowed Chrysler to add higher 1st-gear ratios and tighter shift recovery from one gear to the next.

How much fluid does a 68RFE torque converter hold?

Add approximately 10 quarts for stock pan or 14 quarts for deep pan. Apply the parking brake.

What year did the 68RFE come out?

The 68RFE came out in 2007 and typically came behind the large gas V-8’s and the large diesel engine applications and have been modified with aftermarket parts from the beginning. We all know that these motors are capable of putting out all kinds of crazy horsepower and torque. Fast forward to 2019.

What is hot for a 68RFE?

NOTE: The transmission oil temperature must be between 80 – 110°F (27 – 43°C).
