I would also check the shift cables to be sure they were still "snapped" into the clips that hold them in position against the side of the transmission.

I am not sure what transmission fluid was used but my indy 99.99% time uses OEM parts; I doubt he used anything but Porsche

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

First and foremost, thank you for your time in advance.
I am having trouble with the shifter in my 2003 996 C4S manual. It started with particular difficulty shifting up or down into 3rd. Now, the difficulty is being experienced in all gears, when moving, though sometimes its easier than other times. Driving conditions are standard, temperature outside is always between 70 and 100. Engine temperature is always around 180. Transmission oil was changed at the 90k routine maintenance. The clutch resistance never deviates, it is standard and, once in gear, I have not experience any slipping. When in gear, there are no issues. The difficultly is only when getting "in" and, to a lesser degree, when getting "out." The shifter is smooth and without issue when the car is still.
Any thoughts? I have a dread that its the syncros in the transmission though everything checked out at the 90k.
If this were my car. The first thing would be to bleed the clutch slave cylinder. (and the brakes while I was at it)
I would also check the shift cables to be sure they were still "snapped" into the clips that hold them in position against the side of the transmission.
Yeah, using anything other than the oem fluid can be the cause especially when cold.
At your mileage worn engine & transmission mounts contribute also.
Thanks for the responses, guys (gals).

How difficult are the bleeding / cable jobs?
