Is the trail pedal. Super easy button in middle of selector switch. I dont use speed control. Its a but of a cheat code. I think its NECESSARY only in 4L crawling in 1st and 2nd.
Are you guys using trail pedal when this occurs? If not, curious if one pedal drive will elevate the issue. I use it to take the play out of the Tcase chain slop I feel in 4L (1st and 2nd gear).
