There is a TSB out from Volvo to fix transmission shifting problems by updating the TCM's software. You need to take it to a Volvo specialty shop who has DICE diag. system or to the dealership to have this done. Here is a reference: A/T Controls - TCM Updates For Various Issues/DTC's 16761 Transmission Control Module (TCM), Software (SW) Date 12-23-2009 Reference: VIDA Let us know what happened. Zee
