A/t Transmission Check Light - Getting Worse?

[jackbh241]

I've had this issue for a while but it comes and goes and is progressively getting worse. I keep getting the A/T Transmission Check Light (AT Check). It used to come on periodically, usually during "spirited driving" in tiptronic mode however for the past 2 or 3 days it comes on as soon as I put it into drive and stays there for the entire drive. Transmission dipstick says it's full of fluid (although It's probably been a while since it was replaced), Just did an oil change so that's full. Any thoughts?

I also occasionally get a clunk sound between gears after driving for a long time and usually between 3 and 4 or if that helps?

On a side note, this is also similar to the airbag light that used to periodically come on and could be removed with the key to reds then off method and then it would dissapear for months but now it comes on straight away afterwards. Could this be related? /anything I can do about that.

Any help would be greatly appreciated

There are hundreds of little electrical gremlins in my stagea (2004 M35 250tRS4 btw) haha.

Without the code it is near on impossible to guess what is wrong with the trans.

You have the 2004 model M35 that wasn't allowed into Australia? Are you NZ? I don't think there are many differences, just checking...
