Transmision fluid again

[los36]

I know this has been covered ad-nauseum.
I purchased my 6-speed 2001 S w/ 95,000 miles in July. Not seeing a transmission fluid replacement in the service history, I decided to do it myself. I used the Porsche classic transmission fluid that Pelican sells. 3 cans until it dribbled out of the fill hole.
The fluid that came out was very clean, so I suspect that the previous owner had done the service themselves recently. Since I replaced the fluid, shifting has become significantly worse. The 986 hard 1st and 2nd gear engagement is present now where it previously was not. All gears take more force than previously and the engagement is notchy.

So, did I choose the wrong genuine Porsche transmission fluid?

….ask Pelican if what you bought is correct for your car. They are solid folks and will help you.

I think that I found my answer after some more research. Even though the oil is recommended for the Boxster, it is a GL5 fluid. Not sure if the description is from Porsche or was written by Pelican, but the recommendation may be incorrect. I've read in other threads that our cars require either the other Porsche genuine fluid or a GL4 fluid.

Porsche Classic Gearbox oil (PCG-043-210-52-OEM) DON'T USE THIS:




The correct transmission fluid (000-043-305-49-OEM) USE THIS:

I think you have a different problem with your box than GL4/GL5. I use a fully synthetic GL4/GL5 gearbox oil and also follow the specification, but the differences would never be immideately as significant as you describe, only in the long term. Your box has a problem imho.

No, he is correct, these gear boxes are extremely sensitive to lubricants.

How do you like all the hoops Porsche makes you jump through in order to gain access to the transmission? And their requiring a triple-spline bit for the fill plug? It's almost as if they were trying to discourage DIYers.
