i’ve put over 25,000 on it since the lifter issue

now the transmission is done , and it has sat at dealer for 3 weeks and no one has touched it since

Parts shortage. No one can get anything right now. Cant touch the truck if you dont got a tranny to swap in. Its gonna happen with any manufacturer if your tranny fails youll be waiting some time.

  IDK the exact process. I would suggest contacting one of the staff, found on this page: https://www.gm-trucks.com/forums/staff/

  I did look for that when redoing this account but found no option for it. If you know how please point me in the right direction.

  Also Look into the New Range RA010, It does all the features of the RA007, plus inbuilt throttle controller and code scanner/clear from your phone.
