I'm having a similar problem with my 1.8 Auto. This morning, driving up the slip road to join the motorway, the engine started screaming at me, realising something was wrong, pulled over straight away.
Tried reverse, okay, then driving forward again, realised the car wasn't changing out of first gear. Then noticed that there was a warning light (manual tells me it's the transmission warning light). Called the AA, they took a look at it, and decided it was best to tow it to the gearbox company that had only just rebuilt the gearbox some weeks before (that is a story in itself).
When we arrived at the gearbox company, the AA man noticed that the warning light had gone out, something the gearbox company said would happen if the car was turned off and on again. So, with it at the gearbox company at the moment, their diagnostic wouldn't talk to the car's computer, so they have no idea at the moment what the warning was for. I've had to leave it there for them to resolve.
Just completely fed up of the constant gearbox-related problems that I feel should have been sorted out thoroughly in the first place when I paid for a full rebuild.
Will post an update when I have more news about what is wrong should it help anyone here in the future.
I took it back to the company that rebuilt it in the first place. I don't have much faith in them to be honest. They said it was throwing up a P0500 fault (Vehicle speed sensor), that their computer couldn't talk to the ECU properly, and loads of other faults were being thrown up. They told me I needed a new ECU at £350, but they were unable to source one.
Took the car to the local garage who had a quick look at it, confirmed the faults being reported, unfortunately, they were away for holiday, so took it to another local gearbox company, who whined about not knowing the problem because they hadn't rebuilt the gearbox, the car has been with them for about 2 months while they bu**ered around with trying to find a unit for testing. They then told me they couldn't get a testing unit, so decided a purchase was necessary, at £175. So, waited for them to get one, they tried 2 suppliers, then eventually after chasing up told me to collect the car, because they couldn't help further. What is wrong with gearbox companies! The finaly week they had the car, they did nothing to persue a solution, and I'm collecting it later today.
What I did discover that may be a help to anyone here, if you have this gearbox fault, when the car is reset (after turning it off and on again), put it into Manual mode and move up to second gear. So long as you keep the revs under 2000, and under about 50mph, you can drive the car about, so it isn't completely dead in the water.
I did also find out that the wrong type of spark plugs can cause ECU faults, and to avoid NGK plugs. I'll be interested in seeing what plugs I have in there when I collect it.
I've tried looking for a replacement part on my own, but it seems that there are none listed within the UK in stock. The list price (probably trade) should be about £112+VAT. So, what is my next course of action? I'm contacting an ECU repairers to see if they can actually repair it. They say it's not one of their listed repair items, but they are happy to take a look, and won't charge if they can't help.
