    Programmer/Tune Question for RevMax 550 68RFE

    I just destroyed my 140,000 mile OEM 68RFE transmission in my 2012 Ram 3500 DWT with the 6.7 Cummins.

    This truck is used to pull 20K-34K via gooseneck and Pintle hitch between KC & The Colorado mountains.
    Our CO property is at 8500’, and I pull 7% grades for up to 8 miles in the mountains.

    My truck currently has a H&S Mini Maxx, 5” exhaust, studded heads, billet flex plate, & EGR & other deletes.

    I am wanting to install a Revmax 550 with the upgraded billet shaft.

    I know that H&S is defunct but does anyone know how to add the transmission tune?

    Is it an acceptable option?

    I only use the mild (second) level on the mini maxx and have never had any issues with it.

    Thanks in advance!

    We would not take a chance with the H&S and a Revmax trans friend.

    I can help you with the RevMax 550 but when it comes to the H&S, I wouldn't want to spend all that money on a new transmission and put trans tuning on it that hasn't had support in years.

    Last I heard you need RevMax approved trans tuning to install their transmissions.

    H&S would definitely NOT be on that list.

    We can still sell you the parts but if the customers tuning is not approved then they would not provide you with any type of warranty.

    Also, if you run tire sizes over 35" and don't have proper documentation of having the truck properly re geared they'll not provide any type of warranty.

    Get the trans tune from H&S and add it it was written by Revmax!!

    Call Tom or Frank the will tell you that you can still add tune if you pay for it!!!

    Should be available on eBay or from someone out there!!

    Be sure to use a Revmax flex plate and get rid of the factory shim washer or you will damage the pump and the old flexplate.

    Ask me how I know.

    I use RaceME Ultra Transmission tuning.
