Hard/Notchy Shifting
I have a 2000 Boxster S with 68K miles on it. Even with careful attention to fully depressing the clutch and moving the shifter smoothly through the gate the car has hard/notchy shifting. (There is no gear grinding though.) This is partiularly for 3-6. The clutch engages nice and far down on the pedal travel.
My mechanic has looked at the car and says the cable length is good (possibly slightly long, do these stretch over time?) and the ball/clevis connections at each end are also OK as well as trans lube level and type. He has also driven it and says the shifting is normal. It seems to me though that it should be smoother like for 1st to 2nd. Any thoughts or suggestions? Is there anything possibly hanging up in the shifter mechanism under the boot itself that might be causing this? Thanks! |
Have the mounts (engine/transmission) been looked at? IS the "notchy" feeling there on both up and down shifts?
|
When was the last time the gear box lube was changed, and what product is in it?
|
Thanks folks! Both good comments.
It seems slightly harder on the upshifts. I am not sure when the lube was changed so likely just a good idea to replace it. My mech said it is not a type that causes harder shifting; there was a particular brand he mentioned. |
First of all, a lot of people have tried a a lot of different gear oils in these cars, and most "after market" gear oils cause shifting issues like you mentioned and noise issues; all of which go away when the car is swithced back to the Porsche gear oil. Do a search, see for your self......

In my opinion, all 986 Boxster tranmissions are notchy, a bit clunky, and somewhat hard to shift as compared to other modern day cars. My 2002 Mini shifts like a dream compared to the Boxster.

A bad front motor mount will impact shifting quality and at your mileage if it's original I guarantee it's shot. The early design doesn't last. The upgraded 987 mount is much better. I would eliminate this first and see how you feel about the shift quality.

Thanks everyone for all of your good comments/suggestions!

Interesting. The shifting is great.

John - I recently replaced the 2 transmission mounts on my 2000 Boxster. With the new mounts the shifter and clutch feel are both smoother, less "gritty", than before. At 12 years old your mounts (2 supporting the transmission, and the front one supporting the engine) may soon start to fail. The tell tale signs are: increased vibrations from the engine compartment especially when accelerating and decelerating, rougher feel in the shifter and clutch, and the seals leaking dark, viscous oil.

Not knowing how old the transaxle lube was I had it changed last week. The front motor mount is being replaced tomorrow with the upgraded unit. We'll see how it shifts then!
|
Changing the worn out (cracked around about 2/3 of the perimeter, gulp!) front motor mount to the 987 type really improved the shifting plus the car seems to idle more smoothly and have an overall more solid feel! No more slight rattle when I shut down the engine either! Thanks Bernese Mountain Dog!
