Transmission problem
1998 Jaguar XJ8 V8 Two Wheel Drive Automatic 130000 miles

My question is

What do the code tell me

Is the sensor broke or the box

I can drive but I will not do so till I get an answer.

My hope is new oil and filter will fix it.

Do you

Unfortunately, new oil and filter will most likely not cure your problems. Possible cause could be the J-gate module. It supplies the transmission control module with info on what position the gear selector is in.

Before that, check the mounting bracket where the shift cable attaches to the side of the transmission. These have a tendency of the bolts working loose causing the cable to move around which in turn does not select the correct gear in correlation to what the J-gate is indicating.
