Jaguar Repair Problems? Ask a Jaguar Repairs Expert.
Hello and thanks for using justanswer.com
Unfortunately when the engine will rev up and then bang into gear when engaging drive and accelerating from a stop this is due to a mechanical failure specifically the forward drum inside the transmission. Of course we should start by checking the fluid level and condition. Since there is no dipstick this is not easily done. A level check plug needs to be removed with the trans fluid warmed, engine running and vehicle on a level surface or lift. We also need to have the vehicle scanned for the stored fault codes. A Jag factory tool will be needed to do this but we can try a generic OBD II scan tool to see if we can read any faults in the ECM. This tool will not be able to retrieve fault codes from the TCM. If the code is P1722 then it is usually internal. Let me know.
