no shudder in reverse. i use to have the obd 2 scanner and scope but lost them in fire ill have to have friend run codes for me. fluid not burned. I was a mech for a few years till i got tired of it. i'm more of a drivability and motor mech not alot of trans exp except for r&r. just wondering if anyone here has had this issue and got it resolved.
