Recently I had my dshboard warning light come on with the following message: "Transmission Service Required" followed with the 'check engine' light.

I took the car to my regular Volvo mechanic who wasn't available (vacation). His assistant hooked the car up to the diagnostic and the following code (and message) was reported:

TCM-012B Neutral control. No neutral control. lblFaultCurrent


The car is a 2001 V70 Cross Country with 122,000 miles on it. Service has been routine with no skipping of regular service. Transmission fluid has been flushed regularly every 30,000 miles. Currently I've had no problem with the transmission shifting although on occasion the car seems to slip out of gear at stop lights but re-engages when I start to accelerate. Other than that I've not noticed anything out of the ordinary.

At this juncture I'm not sure what's going on but, as one might imagine, I'm hoping the code doesn't indicate a replacement of the entire transmission.

Any input or insight would be greatly appreciated.

Back in the old days, I would have said that the PNP switch is starting to go. So, try this:
Turn the key to pos II (on) with the engine off. "row" the shift lever fron R to L about a dozen times. Turn the key to off and the shifter in P. Start the car and see if the message goes away. If that "fixes" it, you will need a new PNP switch. BTW, PNP = park, neutral, position switch.
