2nd Gear when cold--The riddle?

"Stone Cold!"...In this heat wave???? Write back next month when it's cooler than the surface of the sun...

I think all of the things you did help. My theory has always been that cold thick oil (or perhaps old worn parts creating more friction) cause the input shaft to spool down too quickly between engagements and the second gear syncro just can't spool it back up. With hot oil there is less drag on the shaft when freewheeling between shifts.

When cold, a double clutch helps because it allows you to spool the input shaft way up in neutral and then allow the second gear syncro to slow the shaft as you engage second.

Agreed - I can get into second gear fine the past few weeks - it's 90+ degrees when I leave the house.

In the cooler months, I did have the 2nd gear issue as well.

Redline in the box helps a great deal too.

 

Bingo.

 

To be honest, I did it by mistake. I always go 1-3 leaving my house - one day I forgot and went 1-2 and it just worked. Ever since then, I've been going 1-2 without issue. As soon as it gets cool again, I'll know exactly if it acts up again.

My second gear is easier in the summer. I have no climate control so my transmission oil is in the 30's in winter, 90's in summer when the engine is cold. It may be that is the only difference that is required. When it's 30 degrees out second gear comes in after a few miles. I can't imagine the oil get's that hot before the trans gets smooth. Only a guess. But with the redline it has gone from impossible to merely difficult on those 30 degree days.

 

I'm curious about the conditions in which this helps... as I've tried double clutching to no avail.

I'll be overhauling my clutch slave and switching over to Redline NS shortly, gonna keep my fingers crossed!

 

If you watch our top video (around the 5:00 minute mark), I demo the second gear double clutch upshift.

Try this experiment....when cold instead of shifting to second or skipping it and going to third, go to neutral with the clutch pressed and give the input shaft time to spool all the way down (10 seconds.) Now try third...if it is cold, I'll bet third won't engage. The reason third works when cold is it requires a lower shaft speed than second for the syncros/gear dogs to engage (less work for the syncro). If you double clutch (let go of the clutch in neutral and blip throttle) you can spin the shaft up (3000rpm min when really cold) and then quickly de-clutch and grab second before the shaft spools down.

So the question is "what is the difference between double clutching to 3000rpm and normal shifting at 3000?" With a normal shift you have to get through the gate and it slows you down...With the double clutch you are already in neutral with the shaft spooled so you can instantly clutch in and grab second before the shaft can spool down.

Having said this, when it is below freezing, it's just not worth the trouble, go to third.

Edit: In the next scene of our video I try to shift to second at redline before the car is fully warmed up and it balks. I try to double clutch it in with no luck and have to settle for third and a shot to my ego...my daughter is not happy because I let the tail slide.

I remember from the movie "Scent of a Woman" the kid driving the Mondial t can't hit second and AL schools him on how to double clutch it in (except that the Hollywood writers get it wrong.)

Second Edit: the second gear double clutch is not my discovery but was taught to me by the salesman from Shelton Ferrari during my test drive (reminiscent of the scene from "Scent of a woman" except that I was the grey ghost and the salesman wasn't blind.

I think it's from all of those hot shop lights under there warming up your tranny oil!

Actually, this summer, I've had little trouble shifting into second from cold start. Probably an ambient temperature thing in part, as I certainly have not had a drivetrain rebuild this year. Ambient temps have not been really all that far below operating temps.

 

Very interesting.
On my car, I never had a real bad 2nd gear when cold, it would just be a bit stiffer but never bad enough to not be able to use 2nd gear.

However, immediately after changing the gear oil (Ferrari supplied me some standard Agip gear oil) 2nd gear shifts very smoothly cold or hot. I'll be interested to see if it gets back to its formerly stiff second gear over time. Well see.

I have the same issue when I take her out. It is not that bad but it helps if i drive on 1st for a while before shifting. I will try double clutching and will let you know.

I have a slightly different observation. First of all, I always warm my car up for about 15 minutes before the drive in any season. That's enough to get a little temperature to show on the oil gauge, or soon after I leave the house. Hot or cold, mine goes into second gear easily as long as I'm not iin a hurry to shift. In other words, if I'm racing up through the gears, it might not go into second even if I've been driving all day. But if I make sure to push the clutch all the way to the floor and count to 1 before making the shift from first to second, it always works, even when cold.

Just skip 2nd for the first few minutes of driving. it is free!

 

2nd is stiffer at first but it has shifted in without a problem. I have never driven it below 35F as I pretty much only drive it with the top off.

The transmission was recently tuned. New clutch, seals, and even adjusting the forks.

 

redline gearbox oil. Problem solved.

 

There is a mechanical fix for this that by all accounts works. I have NOT done it.

Check the DIY threads above or Google to find the article.


The fix involves drilling a small hole between two chambers within the tranny to allow the gear oil to move more easily.

 

I think this is the thread you are looking for:

Same here. Since I replaced the gear oil (Also Ferrari Agip) the problem has been gone since. Did this mid summer so the summer heat made no difference either way. They may just like the official brand gear oil. Who knows.
Dave

 

Yep.


I have not tried it so ...............

 

What we want to hear - with an ice cold second gear .......
Is a big fat grinding noise - just like all the other boys .......

We need to get over it. We can't, nor do we want to, turn a Ferrari 5 speed tranny into a Nissan tranny. It's a Ferrari box - - and like a special woman, she likes to be warm and cozy, and be treated to respectful and loving foreplay. She's not all that demanding. Just....... "go slow, at first". It's as simple as that. Then, LOOK OUT" !!!!

True, one brand of oil may seem to solve the "problem" more quickly than another - - but honestly guys and gals, within a very few minutes, talk of second gear difficulties become a quickly forgotten, moot point

December is here, so - - HAPPY HOLIDAYS!!!

So, Joe .......... aside from "try this oil instead of that oil", do you agree with the perception that this second gear issue is simply, "the nature of the beast"??

Be well,

Hank
