Please help. I have a 2008 Volvo VNL 670 with the automated ISHIFT transmission and volvo D13 engine. The problem is only with reverse when turning left or right or on a downhill. The truck will stop, move couple of inches and stop and it will repeat the process. When its on a flat straight line (no hills) there is no issues. I have no other issues or codes. I took it to Volvo repair shop, they inspected it and said there are no codes, they pulled the tranny out and driveshaft and can't find anything broken internally or externally. Could the problem be the differential? right now the truck has the driveshaft out and tranny out. I have no issues with the forward gears, truck shifts and downshifts smoothly. This problem has been with me for 1 year and i drove it like this with no problem until i got fed up of the problem.
