I have a 2006 Volvo XC70 with around 180k miles. After a sudden stop and subsequent acceleration, it hard shifts (rpms rev up, car is stationary for a moment, then jerks forward). It seems to be worse when it is warmed up compared to when it is cold. Would Trans Tune help?
Thanks for the question. If the transmission shifts normally under normal conditions, check transmission fluid level and condition. If the transmission has been “run low” or the fluid is dirty, Trans Tune can help the transmission perform normally again by cleaning up residues.
