Hello fine gents

I have a 1998 Jaguar XK8, with 143 000km on the clock. She drives beautifully, but has a regular intermittent fault. She comes up with Gearbox fault on the dash and locks in 5th, with slow pull off. However when I switch her off and on in different gears and play around, she will eventually come back to normal without the fault. Most of the times, as soon as I put her in N, D, P, or R the fault will come back, sometimes the fault stays off and she will drive perfectly.

Gearbox changes are smooth, she doesn't clunk into gear, she is really smooth.

I am thinking it could be a dirty connector, low battery voltage?

Could it be linked to the shifter or gearbox connectors?

Where would I locate these connectors and how many are there?



Thanks so much

 

Failing batteries can often cause transmission issues. How old is yours?

 

also check your left rear wheel bearing! the abs sensor input must be accurate

Thanks guys, the battery is old. I put it on slow trickle charge over night, I haven't experienced a Gearbox fault again, but now the car seems to be missing, felt like between 1- 3/4 plugs weren't firing, again its intermittent, from driving fine to missing some, then missing a lot, then back to mild missing, all over a couple of km. She seemed to rev fine if I put her in Neutral.
Cause this still be a battery cause.
