Hey all, lately the 4 speed auto has been playing up, rather unusually. And I have noticed that this has only happened at night, and is usually a week or so inbetween incidents. What happens is I could be driving along a flat road doing whatever speed, and it will all of a sudden have a hissyfit as to which gear it should be in. It will shift down a gear or two, then shift up again, shift down, so on. This will happen from anywhere between 2 - 5 seconds. But tonight was the strangest. It would shift down a few gears too many and rev very high (I was doing 80) and after its few seconds of messing around with the gears it would stay in third, even if I stopped. As I took off from an intersection it would stay in third and be sluggish as all hell. The manual shift worked ok, although putting it from 3 to D didn't put it into top gear. Also when I shifted manually the shifts felt a lot harsher than normal, and also it was like this when it was shifting itself.

Any ideas on what's going on here? Could the auto ECU have shat itself? Or is there something else it could've been?

Thanks in advance

Oh and one other thing that's been playing up is the door ajar indicator on the digi dash. This was only happening at night too I think, and is constant. The doors all flash randomly like I was opening and closing them all in no obvious order. Could this have anything to do with it?

Trans is going into limp home mode for some reason (usually overheating, but may be a sensor problem). Run the codes on the trans to see if there are any stored error codes and go have it serviced. If you don't have a trans cooler installed, get one if you can afford it, every auto should have one.

Yes because you have an electrical problem of some sort the ECU is putting the trans into limp mode to protect it from damage.Sort out your elctrical problem and you will find the trans will be normal again.

I would work my way under the car to the auto box and make sure the plugs that go to the auto ecu and box are in good nick then check ur earth lead.

If its happening at night, if you drive with lights on during the day, do you get the same problem happening, or does it behave itself.
