Thanks, I did check this just to be sure and it's in manual mode, isn't bouncing/moving back.

Might want to track down the episode on YouTube and see if it matches your issues. Sorry I don't remember the exact specifics of the show, but it was 12+ yrs ago.

Good luck and welcome.

Thanks for this, will have a look and it might be a good idea to change the fluid regardless!

Don't disconnect the battery. You MAY/MIGHT/WANT to have the transmission codes read. Now... my trans tanked completely... and there was no way too replicate the problem to reveal codes. I'm just saying.

Next... have a trusted shop read the codes.

I'm thinking it's electrical-associated. You could pull the steering wheel... spends a lot of time hunting. Me, after my experience, would just take it in too have the codes read.

Wish I had more for you.

No worries this is really helpful, thanks very much. I have some local Porsche specialists so see if I can get them to read the codes.
