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, they screwed it up they need to fix it.

 

well it can be several things . why did they replace the pcv valve? i honestly dont remember seein any pcv valve in the aj motor. also why did they program the pcm? rule of thumb at any good rover shop is that you programm both transmission and engine modules since they feed off each other for shifting strategys. the jerky feeling might be due to they system learning how you drive and the light can honestly be anything. keep us posted on what fault codes are in the modules and i will shoot my two cents. I worked for Land Rover for 7 years. till i decided to venture on my own.
