Zf4hp24 Valve Body Manual Park Solenoid
A call to ZF Australia got me a parts list/diag and I've ordered replacement springs and main body gasket.
There's no write-up and apparently no on-line ATSG or ZF manual that describes the landrover valve block similar to the BMW one. There are quite a few differences vs the BMW ZF writeup.
Mine is gearbox out but this is OK to do with gearbox in as it is filter (3 bolts) then 13 additional bolts to pull the valve block.
The BMW writeup is here. ZF 4HP22E Valve Body Rebuild
Pull the filter + 13 bolts as shown in RAVE. One bolt different from the BMW writeup from memory but follow the rave. Then pull the valve block and take it to your clean bench,
The order you'll probably go in is MV5 (throttle valve), MV1/2, Lower front block (shift connector), Lower rear block, then main (channel plate).
Use a bolt cardboard layout (i.e., shoebox) to keep track as in the writeup above.
Mine was in beautiful condition compared with the BMW writeup. Very little clutch powder and no swarf. Did not need to clean the gasket as it came off whole.
MV5: 5 bolts, not the one nearest to the filter o-ring. No balls/domes, but check throttle orientation.
MV1/2: BMW no balls/domes, but the landrover has a 0.22' white ball.
Lower front. One difference vs the BMW writeup - one of the domes is cup down vs bmw cup up.
Lower rear. Things are getting quite different. Dome orientations are the same, but some variants have a 0.22' check ball in the slot shown. Not supposed to be in mine.
Main/channel block. Completely different from BMW, but I was getting careful by now and got it apart without disturbing anything. This is the layout.
So what was broken with mine? It turned out to be the Lower front valve block Valve #2.
Both springs had broken and decided to do the dance of death. No way I'm getting these apart.
So happy I found something wrong. The rest looked like it had done 3000 kms, not 300,000 kms!
Hope this helps!
