I assume the correct gearbox oil was used as they dont like any old atf.
But does it comply with the ZF specifications that seem to specify only one type of ATF to be used?The oil used was Liqui Moly TopTec 1800, which complies with Land Rover 500050 specs, at least according to Liqui Moly.

Although solenoid resistance is an easy thing to measure, it unfortunately only tells you the condition of the solenoid windings. The issues with the 6HP26 solenoids generally relate to mechanical wear rather than to an electrical problem:@Bemble, can the solenoid resistance be checked to rule out heat issues on the relevant solenoid?
As I've never come across this issue before, I certainly wouldn't rule anything outCould debris in the solenoid cause the issues and when the solenoid is used in conjunction with other solenoids to create a other gears could this hidden?

The complete solenoid therefore needs to be tested, at different fluid temperatures, to establish its current vs pressure characteristics. A typical solenoid test is shown at 3:30-4:30 minutes in this video:
I get mine tested at Valve Bodies UK at Wallasey

The human race is addicted to complicationJeez, so the simple solenoid has now become a more complicated unit that requires more time to verify its effectiveness on both the electronic and mechanical aspects!! I'll stick to my 38' and it's zf22 box.
Great info @Bemble

Oh dear mate, I hope they do as they promise and you back on the road soon!And the story continues... I hope.(oh it will)
148000 miles Make sure the cooler and pipes are either replaced or flushed.Well, now the gearbox broke almost completely when I tried to pull my friend's car out of the snow onto the road.The box started slipping and after turning off the engine, it refused to start until it cooled down enough. When the car started, reverse worked ok, but forwards only gear 4 was in use. Luckily, the service repair shop I use was only a few kilometers away, so I was able to drive the car there.When the car cooled down for a quarter of an hour, the gears started working again.
I decided how to handle the matter relatively quickly and contacted a repair shop specializing in gearboxes. From them I got information about possible faults and repair taboos with price effects. On their recommendation, I ended up ordering a used gearbox. They promised to take care of the delivery directly to the repair shop I use and to instruct them in the exchange. The used transmission comes from the Netherlands and is from a 2009 Range Rover with 148,000 mileage, the delivery time is about 10 days. The total cost, including work, is estimated at €2,500.
And the story continues... I hope.
