Fault Code P07AD-07 (2F)
Whilst out on Friday, I was accelerating to overtake another vehicle and the vehicle seemed to hesitate for a moment and I may have heard a 'clunk'. Vehicle seemed fine after that and drove home ok.
Just popped out this evening to get some fuel and found it difficult to reverse. Needed a lot of revs to back the vehicle up. Then when I pulled off the drive and accelerated down the road, it seemed very slow to pick up.
After I'd filled up, I pulled into a parking space and read the faults codes. At that point a Transmission Fault warning came up on the dashboard. The Following codes were present: -
P07AD-07 (2F) - Transmission friction element F - Stuck on - General failure information - mechanical failure.
U0402-64 (2F) - Invalid data received from transmission control module - Algorithm based failure - signal plausibility failure.
Cleared the faults and then drove a short distance and checked them again and the faults haven't re-appeared.
Did have the gearbox flushed at the last service back in November. Have done <1000 miles since then. Current mileage is circa 40k
Had a search around but can't find that specific code.

Took the vehicle out for a 22 mile run this evening.
No fault codes but the gear box change seems clunky and hesitant to change up.
Also when reversing need to apply quite a lot of revs. Like if a clutch was slipping.
Any advice welcome. TIA Discovery 4 HSE - Aintree Green

Who did the flush because it sounds like its about to give up , Was there any reason to do it at such a low mileage. That transmission is pretty bombproof so something is going on.

Flush was done by a reputable independent LR specialist. I trust them and don't believe that the flush has caused this issue.
Probably didn't need doing at such low mileage but my D4 is a keeper so it's a preventative maintenance.
Not sure what oil they used but I imagine it was the right stuff. Going to book it in with them on Monday and get it checked over.
Will report back findings!Discovery 4 HSE - Aintree Green

Just to close this down...
Turns out I had a transmission fluid leak due to a faulty 'O' ring.
All sorted now and gearbox back to normal.Discovery 4 HSE - Aintree Green
