DFM Disablers for 2021 AT4

[GrayGhost]

Trying to find a DFM disabler for my 2021 AT4. Most say they will not work with 10 speed transmissions. Any suggestions are appreciated.

Ah I ran into the same issue on my 2020 AT4 with the 6.2. I tried the range OBDII dongle but the transmission couldn’t figure it out what it wanted to do so I reached out to Range and they shared that is common in the 2020 and 2021 and setup my return and recommended the Pulsar LT. So far it is working great though I’m not sure if I’ll ever use some of the features like tire size calibration or throttle pedal sensitivity adjustment etc.
