driving through gears 3-4 service light is illuminated and is gearbox fault its not got a clunk to it. its only happened when the engine is cold first thing in the morning. restart the engine its ok again
needs code reading and a look at live data. Probably pressure regulation fault. You will only get a clunk if it's not in third gear when it goes into default. Early stages will work OK after restart.
