I finally got the trans off the parts car. The coupling was rusted. Someone said in another post to just use a extension ratchet and a hammer-That did the trick once I got a good corner shot to hit
Before I sink some cash into Swepco fluid I filled it with some wall mart 85-145 weight gear oil. This is in case the trans is bad and to give it a good rinse.
I never saw 85-145 weight fluid before. I guess it means up to and all in between. Is it ok to run for a week or two with this general fluid? The fluid was low and dirty on the parts car. No leaks that I can see.

I knew that positive thinking thing wouldn't work.

The Porsche recommended viscosity range is 80 - 90 iirc. The 85 - 145 multigrade is correct at the bottom end, which is good for when the gearbox is cold. The 145 top-end will make it a bit heavy when it's warm, so you might have a bit of trouble attempting fast changes and your gas mileage might go up a bit, but overall I don't seem that any harm will be done.

Still, change to the correct grade as soon as you can.

Common misconception that heavier oil is better. Not true for either engines of transmissions.

The idea of using inexpensive stuff for a short time to flush is good. Using the wrong viscosity not so good. But not fatal.
