Gearbox operating the switch. Once continuity was flowing I moved the gearbox aroundo,  rolled it, bumped it and all stayed good.

Don't know... have trouble with my TC not engaging . Recent gearbox and o/d overhaul. Will engage when cold but that's about it.After 2 or 3 km''s gives up. Sure it's not electrics, checked everything out. Replaced the relief valve assy with no improvement. This morning I thought I'd found the problem. Removed the pressure filter, plug was loose and filter was full of crap. Cleaned it out best I could. Better but still not right. Ordered a new filter from Rimmers. We'll see what happens. Costing more on oil than anything else.

mazfg is Dtype on the 2000 its J type,  i found the inner piston in the solenoid was sticking , needs a thin 1"af spanner to undo the sol,
dont grip its case you can wreck it,  and remove the small  10mm  circlip inside and pop the piston out for a good clean and all intermittent mind of its own solved  dont need to drain the oil either .

mazfg,  have you tested the holding coil  current should pull in at 10 amps and the switch to 0.5 amps , theres a switch mechanism in the end of the solenoid can be very corroded over the years   ( some  later ones are solid state you cant service the contact)

I now convinced my problem is not electrical, I've stripped the solenoid (J type) cleaned it up and replaced the O rings. I'm sure that it's working as intended and my problem is hydraulic. I'll see if the new filter improves things. At the moment it changes normally for the first 5 minutes or so and then stops working.

nang,
Is it the same in both 3rd and 4th? I had a problem on a Stag where it would work when cold but not when hot, with different sensitivity depending on gear. It turned out a previous owner had fitted too many washers under the inhibitor switch. I removed one and the problem disappeared.
Hydraulic problems that cause it not to work when hot are usually down to leaks and/or low oil pressure. They generally go through a phase of being very sluggish with a very soft engagement before finally giving up. The problem I had on the Stag wasn't like that - it worked great then suddenly it did nothing.

It pulls in  fine and holding current is 0.95 amps. It's rock solid and won't move at that and is in the correct position

Not much more I can dream up , it still has all the snags of inhibitor messing up ,
how about you make up a bypass lead and toggle switch to prove its completely eliminated
Just dont use it in 1 2 or reverese with the od engaged

Nang did you remove the  J  solenoid inner plunger, it should rattle if you  the shake the sol  firmly.
they only seem to supply O rings for the outer body not the piston valve one hidden inside
just a thought

Pete, I managed to get suitable O rings for the inner bits and yes the thing rattles !
I'm waiting for a new filter to arrive before I go into the pump plug. Present filter was full of that looks like clutch lining bits and yes, the o/d was rebuilt recently.
Although I've cleaned the filter the best I can, I'm still not sure it's enough as the gauze is quite fine.

My gearbox and OD is with Paul at http://www.firstmotion.co.uk.
Do od spares also do gearboxes or just OD's?  Might have been nearer to go here. But Paul at First motion knows his onions so hoping he'll have a look...just might be a little more expensive  .

Second Dave Twigger.

His advice solved my problem (old pressure relief valve o rings had hardened). Nice bloke.

Cheers, Dave
