Have Transmission Questions? Ask a Mechanic for Answers ASAP
Is your vehicle supercharged? Is the gear box fault warning on? Does the engine rev up then bang into gear when engaging drive or accelerating from a stop?
Ok thanks. Unfortunately this is most likely an internal mechanical failure specifically the forward drum causing this. The transmission would need to be replaced or rebuilt. Of course we need to first check the fluid level and condition. Since there is no dipstick this is not easily done. A fill / level plug needs to be removed with the fluid warmed, engine running and vehicle on a level surface or lift. If fluid flows out it is full. We also need to check the cable to make sure it is not loose or binding. Since the gearbox fault warning is on a Jag compatible scan tool will be needed to read the faults. If there is a code P1722 then it is usually mechanical. Let me know.
Yes it is possible. This is why the fluid needs to be checked as well as seeing the exact fault codes
