This is a transmission switch issue. That is locate on the side of the transmission. It either needs adjusting, or you need a switch.

SOURCE: 99 jaguar transmission code p1722

This code is an indication that the transmission has excessive slippage, the code is for the input and output turbine speed sensors, based on what i know of this problem the trans has a mechanical problem, that would be low fluid pressure or worn out forward clutches, make sure the trans fluid is not low, if it is ok you will need to have the trans torn down for inspection..

Yes it's in Limp mode it will only run in 3rd gear.

As for the ABS, there is a wire sensor that attaches to the breaks,

If they don't attach that when the breaks are put back on or if they cut it because they don't know what it is your sensor light will be on.

Limp mode xj6

The on board computer (ECM) has put the car in limp mode (reduced power) because it has detected some kind of serious error in the systems operation, this can be the engine or the electronically controlled transmission, it does this to prevent any further damage to the car engine or transmssion or possible fire hazard in the case of a misfire or rich fuel condition that overheats the catalytic converter. You must now have the computer control module scanned for fault code and repaired based on the diagnostic testing outlined for the code inthe factory diagnostic manual..

1990 jaguar xj6 transmission problem

Hi Virtgen

If you have checked your automatic transmission fluid, and its OK.
Does it smell burnt ?
Sounds like you have a mechanical problem in the transmission.

The ABS light on is another problem.
This is usually associated with a rear ABS sensor faulty, due to corrosion in the rear hub.

Give me some feed back !

Please give a FixYa rating Please, ....almost a Guru !
