Hi Guys, Hoping some others that have the 3.0TDI Tip might be able to add to this to see if it's just mine that does it and I've got a problem or if they all do it. I've noticed occasionally when it changes from 3rd to 4th and I'm holding the rpm steady around 3.5K prior to the change, it seems to change once, then a few seconds later change again. It's almost as if it's slipping as it trys to change into 4th, then all of a sudden does change. The change is still smooth. Apart from that it seems fine. It doesn't do it if I'm hard on the power, or at even lower speeds, just seems to be around 3-4K. Going to do a fluid change soon, fingers crossed that might help. I'm really hoping it's not a valve boy/solenoid issue. Thanks Ed.
