    2020 RAM 68RFE Trans Down Shifts From 5th To 4th Very Hard?

    So my 2020 RAM trans has an issue that concerns me.

    Issues are driving a 40-50 mph truck that reads five gears, and if you give her the beans, she kicks down to 4th and slams into it hard.

    Now I haven’t noticed any trans slipping.

    It won't do it casually driving unless going up an incline when it’s in 5th, downshifting to 4th it hit or depending on the throttle given depends on how hard it hits going from start to however fast I delivered her the beans.

    She has excellent response, and the same if the steadily mildly hard throttle is good.

    She’s deleted with the MM3.

    If she’s on her way out was thinking of a Revmax trans.

    Any thoughts?

    I am going to do filters but not holding my breath truck has 74k on it.

    You may want to reinstall your tunes and perform a re-learn.

    After a long-awaited time, I put stock **** back on and took it to the dealership.

    They had the truck for about two months, and so far, they have replaced every electronic sensor on the transmission and the valve body with no luck.

    I got a call today, and they’re installing a new transmission under warranty.

    Before that, they did all the recalls CP for the ditch, and they installed the CP3 pump.

    You are fortunate to get the warranty!

    I tuned my 2021 with EFI Live (before I found out about DRD), and I have heard that with MM3, the dealer cannot tell you’re tuned, but you can see everything with EFI Live.

    Any truth to this?

    The evidence of tuning is also there with the MM3.

    It depends on the dealership and how far they decide to investigate.

    Some year models do, and some don’t.

    My 2018 shows one on the flash counter I’ve had one EZ Lynk tune and four different tunes from Ray on my truck.
