Why won't it start or swing?

SOURCE: GEARBOX FAULT MESSAGE for jaguar s 2001

Replace transmission and sell quickly. I bought 2001 s-type in October 2008. I have not been able to drive it. 1st thing was gearbox fault message which turned out to be transmission. Ford can rebuild cheaper. Next thing to happen was all seals needed replacing. Then all coils needed to be replaced. Coils keep going out. Needs new computer which has 8 year/80000 mile warranty on, but Jag would not honor ($3000). Needless to say my pretty jag sits in the driveway. Had to get another car. Went with Lincoln LS V8. GREAT car!

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.

i had the same problem with my s-type, when i went to jaguar dealer for diagnostic and they told me it was trans problem, need new trans and will cost me $4500 to fix it, so i think you will be better off looking for a salvage trans to put it in your car, it will cost you around $1500-$2500 including labor. i hope that will help some of you with gear box fault massage. oh try and find some one who knows a lot about jaguar before you send the car for trans repairs.

Check under the driver side fuse box which below left of the steering wheel if there is any dampness then it s screwing the ecu,this could be due to a seal leak in the window or holes near the axle.ALso the transmission needs fluid to be change as most jag trans fluid need replacing before 75k, clearing the codes will clear the engine light which also improve the cars shifting.

SOURCE: x-type jaguar automatic (gear box fault)

I have a 2002 X type (2 litre. done 44000 miles), dash showed gear box problem, (red circle light up). I pulled out and turned the engine off. 5 minutes later turned the engine on. The engine running but the car would not drive either in drive or reverse. Turned the engine off again and on the car driving but not much power. The care is taken to the Jag. dealer and told is misfiring + some gear box faults. Suggesting to change some coils and see (cost about £200+). also possible need to change the gear box costing about £2500+. Please advice. Shall I go ahead with the repair? Should I part exchange.
