Picked up a 68000 mile Omega on an x plate as scrap, wasn't going to scrap it in any case, but the missus drove it back from Weymouth and it was faultless.


Chucked it in for and MOT and it sailed through.


Guy came to buy it, had money in his hands, but when he took it for a test drive, gearbox went into limp mode, throwing up a warning light on the digital display.


So, can only change gear if you do it manually, switch off and turn engine back on, and it clears the light, gearbox back out of limp mode.


checked fluid, didn't look too clever, so fresh filter and fresh fluid.  car is fine for 30 miles or so, but again, damnd thing went into limp mode.


driving up a small incline, not pushing the car hard, all of a sudden its like its gone into neutral, engine revs climb up rapidly until at some point box sorts itself out and transfers power again, but throws it into limp mode.

engine off and on again, and its out of limp mode.

any ideas?  bloke is wanting to come back to it tomorrow and I thought the problem was sorted.

You need to get a code reader on it and get the stored codes before anything else

If box is goosed, got a good one here if you prepared to remove yourself

check your oil level and clean inside selector switch -on side of gear box http://www.omegaowners.com/forum/index.php?topic=90508.0   and   http://www.omegaowners.com/forum/index.php?topic=90673.0

Ideally needs gearbox codes read. I suspect the fault code will be Incorrect Ratio.

Whilst it may be possible to fix, if the box is off, I think I'd just slap on another known good one instead.

[Galahad]

OK, who's got a known good one that isn't a billion miles away and not a billion quid

[RobG]

If you want to remove it, £40 less selector switch

[albitz]

If you were nearer I would have it myself at that price.

Well you ain`t

But if I walk to the end of my road I will be.
