I searched around here, pelican and johns 964 site, but I can't find a DIY for transmission fluid flush. Anyone do it before?

 

p-car.com has one. I've done it and it's not hard at all.

 

Found it, thx Tom. I just ordered some Swepco 201 from Pelican as well.

First. Make sure you can remove the fill plug... don't ask me why...

 

Swepco is the gold standard for the 915 but I thought Mobil 1 was best for the G50/G64.
Also, I didn't use that tube filling method. I bought an $8 pump that you can pour the tranny fluid into and then pump it in half a quart at a time. It was very easy, assuming you can get those plugs off!

 

Rob @ SCarGO filled with Swepco last time I was in, and it's been fine for me, so I am sticking with it.

 

Is this 75W90 the standard for 964's? My buddy (a Porsche mechanic) told me to use Swepco as well.

 

I used 75W90 recently. I filled the case from quart bottles and a $8 bottle top pump from Shucks. Worked great and pushed in the right amount of oil as it's easy to try to push too much into the case at once. It's not like it's open case, the oil has to flow around the gears and settle into place.

Be ready to see some dirty oil come out of there. I was shocked to see out black it was. I have no idea if it's the orginal oil or not but the difference in shifting once i was done was amazing. Mobil 1 for me.

 

I filled mine with a long tube and funnel attached to the left rear fender. The book said it held 4 quarts, so I poured in 4 quarts. The garage floor was quite a mess.

 

Done! Thanks guys it was easy.
