I don't think the tazer is the issue. Something definitely going on with the transfer case shifting. I am going check couple things before trying another dealer. They will have the complete report anyway.
Yes, I have 2020 Gladiator Sport S, 3" lift 37s and 4.88 diffs.
When I shift in 4H from 2H the transfer case shifts straight into 4L and will not disengage. Under warranty took it to Jeep. 3 weeks and no repair. New TC and few other tweaks. They blamed my Tazer. Unmarried, reconnected original...
