Hi all,

I have a c2s that I bought about a month ago (pics to follow). I cant believe how amazing this car is, both to drive and just look at. It has 107k miles with a huge folder of history. No leaks and runs nice and tight. The only thing I've noticed is that from cold when I change into second I get a slight crunch, if I change very slowly no crunch. This only happens from first to second.

Should I be worried?

These transmissions are not meant for speedshifting. Take it easy during your gear changing and the transmission should prove very robust.

Mine does the same thing when cold. I just blip the throttle a little when shifting and it slips into 2 without any effort. When warm, there is no "crunching" on mine. I don't drag people off the stoplight so I don't worry about speedshifting. Tranny shifts real nice when you're smooth.

Nuff

Mine does this also when it's cold. I just double-clutch from first to second when it's cold. After about 5 or 10 minutes it's fine.

Thanks guys, thats put me at ease. There are so many little quirks that are normal with these cars that as a new owner the common things can freak you out.

Thanks again

I am sure we all have learned to give our 993's that pregnant pause between gears. Recently I had my transmission fluid changed and added Redline Redline 75W-90NS, which has no friction modifiers. The Redline instructions suggest adding a small amount of friction modifier but the installing garage suggest none be added. My transmission shifts "much" better now. Well worth the $.

Change the fluid -- I think you'll be surprised at the results.

+1 Should diminish the crunch factor.

When I got my car 4 years ago and first experienced this problem, I remember someone posted something about saying "paycheck" in between double-clutching. It stayed with me! You should be fine in 5 to 10 minutes.

Sorry for silly Question ..
Could someone explain the term 'double clutching'?

TMc993

"Double clutching" is a method used to match engine and transmission RPM on downshifts. Say you're in 4th gear at the upper end of the RPM scale for 4th and you are approaching a much slower 3rd gear turn. It goes like this:

1. 4th gear - Clutch in - Shifter to neutral
2. Clutch out in neutral - Rev engine to appropriate RPM
3. Clutch in - Shift to 3rd - Clutch out

When done properly and well, all of this takes place much faster than you can read this sentence.

If you ever at a track, standing at a turn that requires hard braking, you'll hear the drivers double clutch...As they go by slowing for the turn you'll hear that marvelous "Whoop-Daaah-Whoop-Daaah" as they work down through the gears.

I am about to purchase some Mobil Delvac for this exact reason... I get some crunching/notchiness into third gear.

Excuse the ignorance, but how much should I order? I.E. how much do our gearboxes hold? Yes I am being lazy, I know I could look it up in the manual

thanks

mrsullivan: If you do a search on this topic you will find that many of us have tried a number of different trani fluids to try to improve shifting. As far as I can tell the Redline does the trick better than any other fluid. Good luck.

Jonathan,
Are you going to do the transmission fluid yourself or are you having a mechanic do it? I had Mayos do mine a while back but I would like to watch someone do it just to see it.

I used to use the double clutching up technique on my old '86 Subaru GL when it had sat overnight at - 20 C or colder. Works well. Sometimes I'd have to do it from second to third as well.

I've only had my 993 a few weeks, but I've noticed it likes "deliberate" shifts. I'm still working on getting 3 - 4 just right, but it's coming.
