You should see if the Transmision Control Module is available for a software upgrade. You could have other sypmtoms aswell. Posted the following tech net.
A function called "Neutral Control" is present on all 2001 V70 and S60 cars. It is also present on 2002 non-turbo V70 and S60 cars built before January 2002. When the vehicle comes to a stop, the Transmission Control Module (TCM) activates Neutral Control. Even though the gear selector is in the Drive position, a Neutral condition is engaged hydraulically in the transmission. Neutral Control disengages when the brake pedal is released or the throttle is applied.
When the neutral control function is incorrect, there are three symptoms that can be felt in the car;
1. After coming to a complete stop and keeping the brakes applied, a "thump" can be felt in the car. It is felt about 2 seconds after coming to a stop.
2. When releasing the brake there is a harsh or double re-engagement of drive.
3. When idling in 'D' range with the brake applied, the engine speed oscillates (fluctuates).
In addition to these symptoms, some cars may set a DTC 012A or 012B in the TCM; which should be erased before downloading the software.
