I've had the same problem on my 2001. It turned out to be the battery. Apparently the voltage had dropped to the point that the computer began to malfunction. I'd first go to a battery shop and have it checked under load before looking for other solutions.

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 !

Check the transmission range sensor, if you already serviced the torque converter and the ECU is fine, you may need to replace the gear box.

Ensure gear box fluid is at level.

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..

had a similar problem with same car. turned out there was a bad o-ring on the heater core, which happens to be right above the TCU. It was dripping on it and causing it to short out. replaced the o-ring and has been fine ever since.(about 60k mi ago)

Transmission is working but light came on

I recommend going toa transmission repair shop and having the TCU scanned for codes and repaired before the vehicle goes into the "limp home mode".
You only have third and reverse in this mode.
