SOURCE: Gearbox fault of Jaguar S Type
unfortunately when that code, and that gear box fault light comes on, its pretty much game over for the transmission. It only a matter of time before performance of the transmission gets worse and worse. BUT that transmission is VERY easy to replace, i would check out a few trustworthy independent shops to give you a better price! I am usually a die-hard dealership, having been working at this jaguar land rover dealership for the last 2 years, but you are pretty much for sure going to be a cheaper price on the labor and like i said it is a pretty easy task.
My only precaution MAKE SURE IF YOU GETTING A USED TRANSMISSION THAT YOU GET SOME TYPE OF WARRANTY ON IT. Too many times have I seen customers loose thousands of dollars paying someone to put a used engine or transmission and have it fail almost right away.
SOURCE: 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.

What codes are present?
There has to be a problem somewhere for that light to come on?
Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c
SOURCE: having a gearbox fault that lights and i can't
Check the fluid level in the gearbox firstly.
Other 2 things it could be are the torque converter or slave cylider for the clutch.
Most likely it is the torque converter as the engine light is on aswell. although these may not be related. you will need to get it on a code reader, diagnostic machine to be sure.
SOURCE: gearbox fault light and cruise not available
The only thing that will cause a cruise control fault is a loose vacuum hose ussually on the breather hose coming from the valve cover in front to the throttle body. As for the remainder, shut off the car and restart to get you home and avoid the limp home mode. That in itself is an electronic fault in the ground system. Check you coils or replace them with a new set of plugs (autolite double platinum recommendes.) Clean any grounds you may have and then start you engine. You will notice there is no problem then. Run a diagnostic tool to see if there is any fault with grounded sensors like the O2 to keep that from happening again. Don't get the tranny replaced cause thats all the dealership wants to do and charge you $5k. Its not the actual cause. Good luck and let us know if there is anything else we can do here at fixya.
