got a gearbox warning on the mid yesterday on our way to Dorset, pull away in drive & its like driving with the handbrake on but if i select the gears manually it seems better. Every now & again warning goes away & its fine, any ideas where to start looking bearing in mind we are on hols for a week & have next to no tools or recomend a garage near to Swanage

Check ATF level. Not a lot else you can do.

As said, all you can do on holiday is check the ATF level. Sounds like it's going in to limp mode. When mine did the same it was my Selector Switch on the side of the gearbox though.
When you switch off the ignition, I believe it resets so you may get a decent run out of it before it goes in to limp again. Using the gears manually obviously over-rules this issue until you put it in 'drive' again.

If you run through each position of the selector lever do the LEDs next to it follow it accurately with no flickering, etc?

If that's OK, worth getting it to a Tech 2 as there should be some codes stored in the gearbox ECU.

As Old Man Wood says. Try to get through the week (but don't labour gearbox), and Kevin Wood is on your way home?

got the car home, cleaned out the selector switch & changed AT fluid but to no avail, scanned for fault codes & got 36 tcc solenoid voltage high, anyone able to educate me please?

sounds like a dodgy solenoid within the gearbox

TCC = Torque converter clutch so the clutch that "locks up" the torque converter around the 45MPH point. Sounds like the electrical circuit to the solenoid is dodgy or the solenoid itself has failed, as said.

I would try checking the 3 large round connectors behind the battery, as the auto box signals go through one of those, and also the connectors on the gearbox itself.

Part the connectors, make sure they are clean and sound inside, then re-insert them making sure they are firmly home.

Failing that, check continuity between the connectors on the gearbox and the ECU (I'll dig up the pin numbers in TIS). If that looks OK, it's probably the solenoid.

Shouldn't think the solenoid would be too bad to change. It's under the front sump pan on the gearbox, IIRC.

Could you remind me of the age and spec. of the car?

Looks like, on the GS8.20 / 8.21 gearbox ECU the TCC solenoid is between pins 32 and 53 of the gearbox ECU. TIS reckons you should see 18-20 ohms between these two pins.

I would put an ohmmeter across these pins and see if it moves as an assistant waggles the rest of the connectors in the system.

If that looks OK, TIS suggests applying a fused 12V feed, positive on pin 53, negative to pin 32, and checking that you can hear the solenoid clicking.

Ahh. No info on TIS. 

Not sure if the above info. is correct, then. Need to dig out the Haynes manual for the wiring diagram.
