The car will seem to engage reverse hard and if it does then transmission fault will display and the vehicle will only drive in limp mode ( no power and acceleration)
it does not always do this, there can be a couple of days at a time when everything is fine, and then the problem resurfaces.
it only happens when selecting reverse.
When the problem has not occurred the car shifts perfectly and sport mode works fine.
this has been going on for about a year now with no change. There is no deterioration in the way the car shifts ( unless the fault light shows up in reverse as described) so it’s
hard for me to see this as a transmission problem
All fluids are new and full and the car just turned over 100k

Welcome to the Forums.

Since this is NOT the Tech Section, I suggest a re-ask in the XJ8/R (X308) Tech Section, down the home page a tad.

Good luck.

Hello, Leighdone,
As Grant above suggests, members of our XJR section will certainly be able to help you out with this transmission fault.
But it IS annoying to have an Intermittent fault like that!
