Thanks for this advice Xsport. I too have a driveway with falls in a couple of directions, and though I thought we had set the car level, I re-checked it again today using a spirit level across and down the car length.
Worth doing, thanks.
Firstly I found the fluid was slightly under level, 0.2L approx.
Next we drained out 4L of the fluid we had put in the previous day (after approx 100Km of test driving) and it was now dark brown whereas it was a nice red colour going in (and we had changed all of the fluid not just half of it, so the colour was a bit of a surprise).
I decided to re-drain and fill again but could not get the same fluid this time, and have ended up using Nulon Full Synthetic SYNATF-4. (Nulon state it replaces the N402 and I believe other people have used it successfully. We have not got the same choices of ATF here in Australia that you have in the UK or Europe, so Ravenol etc are very hard to come by and very expensive)
Nulon SYNATF-4 is the same red colour but nice and clean
This time I'm 100% certain level is correct and fluid temperature was 39 degrees when checking the level.
I also checked all of the solenoid and sensor resistances through the plug pins, in case I had a fault in there. To my surprise all of them gave readings within spec (other than the Lock Up solenoid which read at 13.4 Ohms when spec says max 13.2 Ohms and I think I'll live with that one at present), so unless any solenoids are sticking, they seem electrically to be Ok.
But I DID find that there was water inside the electrical connector when I twisted it open. That may have been causing some gremlins ? I have dried out thoroughly now.
So - results.
An improvement in the "running away" situation on tickover. Not what I'd call perfect but better.
Selecting the forward gears and P or N going up / down, all changes seem to be smooth.
But Reverse gear selection is now quite clonky, worse than it was when I bought the car, unfortunately - and I have installed the new bottom engine tie since. This will need more investigation / work.
On the short test drive it seemed to perform well - possibly slightly cleaner gear changes in both normal and sport modes, but only a few Km's covered so I need to let it bed in and see how it performs over some days, and if the reverse selection improves.
Thanks again.
