1990 Porsche 911 Happened twice and corrected itself.

The 2 times were about 2 months apart

Oct 30th the latest

For some reason the car transmission will not let me get it into gear. It seems to keep spinning the gears. Pushing the clutch in didn't seem to do anything. If the car was started in neutral and I managed to get it in any gear it would shut the car off.

When I finally could get moving after various attempts. While holding the clutch in and giving it gas driving down the road. You could feel the car accelerate a little.

I think there's a slight burning smell sometimes if you stand outside the car. Could be paranoia now

Then after many heart palpitations and with no warning or noises. Everything starts working again.
I was driving when it all synced up again.

That's it in a nutshell

It's a 1990 911 Carrerra 4 5 speed manual

Don't want to get ripped at the Porsche dealer
