Land Rover Range Rover: Hello Sir, Error code P0721 I have

Customer Question

Hello Sir, Error code P0721 I have a very similar problem here on my end on a 2004 Range rover HSE. After I got my water pump changed, I noticed a trans safe prog appear on my dash. Later that day, I felt like the wheel jumped then the check engine light came on. When I stopped at the traffic light to move my truck started off in fourth gear/ high and stayed there for as long as I was driving. I turned the truck off then on then the problem went away for a while but started with the same problem the next day.
*After testing it, got a reading P0721 for output speed sensor . Please I need some help on this as the dealer was not able to tell me a solution except telling me all the potential. Please help me. Thanks
