Vibrations in the shifter

I hope that someone has some advise or an explanation

The first 5 ~ 10 minutes before the engine gets warm I have
a) very noticeable vibration in the shifter (mainly in 2nd gear)
b) the shifter has about 1/3" play forward and backward

As soon as the engine gets warm the vibration and the play in the shifter are gone.

We already changed the engine mount with no improvement

Ideas?

Check your gear oil level.

That's a weird one. Are there any noises associated with the vibration? Also is your engine mount in good condition?

Hi Alden,

nope no noises and we replaced the (worn out) motor mount with a brand new 987 mount, with no improvement.

A bit more information: In the initial 5 minutes when the vibrations happen and you have play in the shifter, when you move the shifter to "the edge" so to speak, you feel massive vibrations like the car wants to jump out of gear.
So I was thinking synchros, but they wouldn't fix themselves....

Remember that aside from the front engine mount, there are 2 rear mounts that support the transmission.
These can leak after some time and could produce the vibration you describe.
Go take a look.
If you see any oil whatsoever on either one of the tranny mounts they need to be replaced.
Happy Boxstering,
Pedro

Chris, did you ever identify the vibration culprit?

not yet, wanted to look at the tranny mounts week after next
I have the suspicion that it's the 2nd gear synchro
