Transmission

Pedro,

Need to replace a leaking Coolant Valve on my  987 Cayman S, two questions: Does the coolant system need drained prior to install? Any tips or tricks accessing the valve? The area is somewhat accessible from the top and bottom but is really tight. Trying not to reinvent the wheel if I don't have to... All help is appreciated! Thanks

From a standstill when going into normal daily traffic at every shift point from 4th on it seems to be hunting for the next gear at about 2000 rpm.  This does not happen when I put the pedal to the metal only when having a soft start in daily commute.  I took it to the Porsche dealership and they couldn’t find anything wrong?  The tech’s said it would not be transmission since the dash would light up with bells and whistles.  So I’m wondering if it has to do with the electronic speed control for auto shifting?  Once up to speed at about 2500 rpm no issues nor hesitations.

I just purchased the 2018 Base Cayman, with manual transmission in August 2017.  Occasionally, like once every 15 shifts, going from first to second gear results in a "clunk" when the shifter drops into second.  Normally the sound for second, and all other gear selections, is a "click" or no sound at all.  I have had no issues with any of the other gears.  My first grind occurred the other day with about 700 miles on the odometer.  I was at a stop sign turning to the left and as soon as I attempted to select second gear I heard the syncro grind and moved the shifter to neutral, let out the

Hi,

I have a 2014 981 Base Cayman w/ 54,000 km (34,000 mi).  My clutch pedal started a noticeable vibration / buzz that gets stronger as rpm rises.  It starts to get very noticeable at 2,500 rpm and above.  The same vibration happens whether in neutral or in gear.  The vibration starts as soon as you step on the clutch pedal and happens both clutch in and out with consistent vibration strength. 

Morning all, I have a rattling sound coming from the back end of my cayman. The engine runs strong, no pulling or hesitation.  I have no lights on the dash and my gas mileage has not been affected. The only light that did come up was to refill the coolant. The sound started the day before the light . I immediately went to the shop and got some coolant and refilled to the appropriate level. The sound seems to lessen with engine reaving. I was thinking of flushing the tranny fluid out and refilling. I am at 82k and just had a inspection done and they stated everything was fine.

Sport plus turns off after being driving aggressivly on the track in hot weather.  Once it turns off it won't come back on until after cooling down.  Is this a problem with the PDK or the electronics?  It has a cobb tuning on the ECG that is modified for the fabspeed supercup race exhaust and the track.  thanks.

I had Porsche of Orlando add the sport mode option to my 2008 Cayman S with the tiptronic transmission. I read in the owner's manual about sport mode & to activate sport mode, one has to maintain 3200 rpm for at least 2 to 3 seconds.  Once activated, it is supposed to start off in 1st gear & the throttle response is supposed to be quicker.  However, my car's throttle response is the same & it still starts off in 2nd gear.

I'm looking for a good local certified Porsche mechanic somewhere W of Washington DC. Any help is appreciated.
