Gearbox fault light shows. Higher rpms between 60-70.

Don't mess with it and take round to yer local Jag mechanic right away before ya blow the hell out of it and you'll be up for thousands of $ instead of a coupla hundred.

didnt specify vehicle --generic answer--until repair is made the vehicle will show engine light and have codes --if gearbox is problem for limp mode /until repairs are made or gearbox replaced you will be in limp mode --and as to sensor find out what one it was --start problem may show back up if sensor was problem --and GET a 3rd opinion you have 2 mechanics with different opinions on your problem and i guess they are reading your trouble codes differently

if the gearbox light is showing you need to get the fault codes out of the tcm (transmission control module) to help diagnose the problem, the jatco auto gearboxes on these cars are very troublesome have replaced many in the past. take a sample of the fluid from the level plug. (small plug centre of drain plug) and see if it smells burnt if so the gearbox needs rebuilding or renewing. hope this helps.

You must have the dealer scan the system with a special tool and based on what is read with the scanner diagnose the problem.

Check the gearbox wiring and solenoids, if all fine than it might be internal gearbox fault.

Hi,
Try releasing your parking brake and having someone push or rock your car. Sometimes the gearbox gets stuck in Park if the car moves after you put the car in Park and let the car roll a bit before applying the handbrake. It could also be a fault with the gearbox itself.
Its also possible that the locking tab mechanism (that gets relesed when you press the button on your auto gear shift) has jammed. If you can get it out of Park do not put the car back into Park ,but rather put it in Neutral after you have finished driving around etc and use the hand brake when parking. At least you wont be stuck in Park until you get it to the repair shop. Note that your car can roll in Neutral, especially if your parking brakes are worn, so take extra care when parking ie point your wheels toward the kerb when parking on any hills or slopes.
Any time your gearbox gets stuck its a fair bet that you need to get your gearbox inspected by an authorized repairer.
Good luck,

It must be having automatic gears. It seems as if the gear teeth have got jammed up and the sensor automatically switched off the engine to prevent further damage. Also check quantity of the gear box. Anyway only a proper mechanic will be able to release the tangle, if any, but my sixth sense seems as if the parking sensor has malfunctioned therefore not releasing the safety feature of driving and thus not responding to the remote starter..........sodeep

hi,change the gear box solonied c.should b ok than ali g autos birmingham 07971335303

Most common fault is the gearbox position sensor. This is like a neutral safety switch located on the top of the transmission where the shift cable looks up.

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.
