Amyhow, I'll bring the car in soon, so hopefully we'll find out.
Any idea if you have an aftermarket shifter like a B&M? If so, your fore/aft bushings may need to be tightened.

sometimes just being a new owner of these cars causes issues to surface that were heretofore unknown. or worse, undisclosed ) hopefully that wont be the case. i say *undisclosed* because porsche was unable to identify "2nd gear pop out" in my first 96 t, but they fixed it under warranty. ppi's miss stuff all the time.

in any event, good luck.

This is why I bought a tip, I'd be clueless in a manual.

Correct, but only when downshifting from 3rd. 1st to 2nd upshift is ok, if a bit notchy (for what I'm used to)[/quote]

Hopefully the guy who drove it back from the PPI didn't do anything foolish.

Thanks! Is opening the box an engine out operation? If so I might as well do the welding of the lines at the same time. I wouldn't be too elated if I have to write a 5-digit check 100 miles into the car, but I guess stuff happens.

no, only necessary to lower the engine to drop the trans. so not "engine out". but the key for you will be to correctly identify that (a) there is a genuine g'box issue or it was ( hopefully ) just an anomalous mis-shift and (b) get to know the car better under a variety of driving conditions and let us know ( well, your indy ) know what exactly is going on symptomatically. it is not uncommon for these gearboxes to require bearing replacements after a number of miles on them, but that wouldn't cause a grinding, so it's still a mystery you need to sort out as to the cause. again, it could've been a one off grind(?).

as to coolant line pin/weld/epoxy, sure thats a great preventative and there is certainly no reason not to do it in the event your engine is out already, although i am of the opinion ( at 132k+ mostly hard miles ) that if they go? i go in, but not before. unless, ( yes ) engine is already out. then, for sure.

i think you need to ascertain and isolate the conditions under which the "grind" occurs and then act accordingly based upon a diagnosis that has symptoms your tech ( or those of us that have gone thru these things ) could help you to *properly* diagnose. i sure wouldn't open the box on a whim or grind though. its too expensive for a "look see".

Has anyone mentioned it could be a clutch issue? Not disengaging completely.

It was mentioned by someone that it may be the clutch. He should relax and let a good mechanic take a look, the rest is just speculation.

in world of probabilities, i'd go with that as the most likely explanation also. it's not hard to do and the stock shifter and throw sucks.

Is the type of gear oil used after the PPI mentioned on your invoice?

Unlikely to be a "stock shifter" issue.

How many times as it happened since?

You say 1/2 shift is notchy? Take it to a good shop and let an experienced tech take it for a drive. Could be a bad 2nd gear syncro/dog, or not....

Cheers

Alright guys, just dropped off the car in the capable hands of Rick Deman Motorsports, hopefully it won't turn out to be a big deal.
