We have a 2006 range rover sc that we just had serviced. They changed the PCV valve and reprogramed the powertrain module, now the car is jerky when shifting and the transmission fault limited gear warning flashed for a second. Car drove fine before we gave it to the dealer. Any help is appreciated.

 

Take it back ASAP. They messed it up, they need to fix it. This isn't your problem.

 

Agreed! This is a no brainer ...take it back to place you had it serviced at and have them correct it FOR FREE. Was it dealer serviced?? You didn't say.

 

yes it was a dealer, I wonder if any damage could have been done to the transmission since we drove on it for a day.
