Gear crunch

I have had similiar issues with my 993 when it is cold, tried various gear oils and found the Mobil 1 Delvac to work the best. But for most part now I just go from 1st to 3rd when cold to avoid 2nd gear all together when the transmission is cold. Works the same way with the Ferrari, as all the Ferrari manual boxes will not shift to 2nd when cold. Once it is warmed up 2nd gear slips right in.
I found generally if the garage is more than 68 degrees I don't have a 2nd gear shifting issue.

There are so many little quirks....that can freak you out. Allfy
But the p. o., who is just a great guy and a member here, did give me an excellent briefing.
We shouldn't be flying these things without first reading the pilot operating handbook.

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

I replaced the factory fill with Delvac/SHC when I first purchased the car, and again this winter. My transmission shifts great.

"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.

For the original poster, change the fluid. If it doesn't get better, it means your 2nd gear synchro is going.

Thanks again,
I reckon I'll change the oil.
One other thing, my left hand side headlight bulb blew about a month ago and again two weeks later. It just blew again today.
Any thoughts?

Chris, at the risk of starting another petroleum based holy war.....................
what lubricant do you recommend for DIY transaxle re-fill?
it seems like a good labor day weekend project
thanks

My car used to do the exact same thing you describe when cold. Now that I live inland instead of at the beach the car's oils start off at a higher temp and the issue has disappeared completely. I don't doubt it may be some synchro wear but its obvously not enough to pull the tranny apart in my case. If your car still grinds after its warm its probably not a good sign.

I have had the best luck with Mobil 1 75w90, the typical stuff sold at local auto parts stores. I havent had much luck with Swepco in the G50's.

wasn't too messy, (only spilled a little bit of the stinky stuff, Robin's DIY suggestion of using a long vinyl fill tube was spot on);
and wasn't too expensive, (~ $40).
how's that for a run-on sentence?
cheers
Craig
Next?

New fluid as everyone suggests. I like Mobil 1.
Also, try this. Sounds goofy. Next time you park you car overnight, 'park' it in second gear. This was posted by someone else quite awhile ago. It actually worked in my case.
