Same car V8 auto
This problem started for me 8 months ago and has not been resolved. I am getting desperate although the difficulties have been eliminated gradually (spent about 3500 pounds this year!)
It concerns the auto gear - not the torque converter, not the valve body, not the gear box, not the drive (all new) - most probably a pressure problem and oil distribution (as I told them last September).
Catch 22 - can't sell it until it works - then I probably wouldn't want too.
Help please at the moment LR garage is checking AGAIN
