Electrically the boxes are the same, the difference is how the engine and gearbox ecus communicate. Irrelevant as you kept your gearbox and engine ecus and looms.  :y

Ok, so is there a way to 'blink code' the gearbox ECU to try and find out what it thinks is wrong? I've got Tech 1 but not Tech 2, and Tech1 doesn't seem to want to talk to my Gearbox ECU.
You haven't tried topping it up yet.
Not to mention the overweight electrical elephant in the corner...

Ensure you have the round plug in on LH top,  re check all plugs are fitted tight...

Pretty sure the round plug was seated properly. I removed it and re-inserted just in-case, but fairly sure that wasn't the problem.

The 4 pin square plug above the small sump - hmm - didn't look quite right so I unplugged and re-seated it.

Whilst I was there I might as well unplug and reseat the selector switch connector too.

Didn't bother with the speedo sender - that was working.

Started the car, and undid the GB filler plug. managed to get about 1L more in before it started coming out again. Total now about 8L, so perhaps another check in a few miles time.

Anyhow, went for a test drive - car now behaving properly, and no MID Gearbox warning. So, a tentative success so far, though I'm not signing it off as done just yet. Need another 280K miles on the clock before I'll accept the problem as fixed ;D

Stop complicating things  ;D The gearbox is working now.
Time to concentrate on all the spaghetti that runs around the vehicle  ;D

What's the 2? pin connector on the rear of the box then? High on the box, just in-front of the prop-shaft flange.

Presumably it's the gearbox output sender... Tells the gearbox ecu what the propshaft is doing relative to the input shaft for shifting purposes.

Omega B speedo is ABS ecu generated... BlRt wire that connects the ABS ecu to everything else. Literally.

Set it to Auto mode... It's not particularly well explained, but it is mentioned in the manual  :D
