    8-Speed jerky downshift while braking

    I have a 2020 RAM 1500 limited e-torque (33-gal tank) and I am having problems where I feel every downshift during braking (especially slowly coming to a stop). Does anyone have any advice on what parameters will help fix this (example TCM tunes) any help would be appreciated.

    You can log while it happens and try reducing the OSS for downshift in the shift table it's using when it happens.

    If that flew over your head, I can't help you.
    If in doubt, multiply everything by 1.1.
