The Geartronic of my S80 D5 AWD (MJ 2011, 120.000km) just makes me despair. The following symptoms occur: sporadic jerking when switching automatically from the 3rd to the 2nd gear. Sporadic intensive jerking when changing the drive stage from “Neutral” to “Drive”. The strange thing is that this jerking occurs only sporadicly and not permanently again. It comes to me especially when the engine and transmission are warm. The following works have already been done by the Volvo contractor: error memory read out (no errors) Complete transmission flushing. Current SW played out. Unfortunately no improvement. Now I have a date for calibration of the GT. Supposedly, this is a huge effort. Does anyone have experience with it? Did someone have the same symptoms on his 6 gear GT? Thank you for your help. LG, Nordisk.
