Trans wont shift up or down..gearbox fault light on
Hello jjames696...The gearbox fault light has come on because the transmission control module (TCM) has received a fault signal from one or both of the two trans. sensors....The Output Shaft Speed (OSS) Sensor and/or Turbine Shaft Speed (TSS) Sensor.The TCM has now defaulted to limp mode...A diagnostic scan needs to be run...An OBD II scanner will retrive a P1722 fault code, the only code in it's library for the ZF5HP24 transmission. The WDS / IDS will pull other codes not found in the standard OBDII library (dealer or good transmission shop)
When was the last time the transmission was serviced? Manual shifting will take it's toll on the fluid quickly.
The transmission is sealed, no dipstick (which i think is a bad idea) You can check the fluid level by removing a plug on the passenger side of the case, you should be able to touch the fluid with your finger. Jaguar fluid is VERY expensive, Mobil 1 synthetic will work and meets ESSO specs.
Personally...i would change fluid every 25-30k.
Hopefully all you have is a bad sensor or a stuck solenoid and no internal componet damage.
Good luck, hope this answers your question...please take time to rate my fixya reply.
