Manual slipped out of 4th
 

I worked in the hospital overnight and drove the Z home this morning in 26F weather. I was noticing a strange, very slight chattering sound while driving about 35mph in 4th gear under partial throttle that disappeared with lifting off. Then during 3/4 throttle in 4th, the manual transmission popped into neutral. I shifted back into gear and the problem was gone.

WTF? It's never done this when its been cold before. Sure the shifts can be more viscous feeling and notchier...but slipping out of gear? I think not. And while I was tired from the all-nighter, I'm 99% sure I had it all the way into 4th.

Maybe it wasn't all the way in. I've had this happen on my DD a couple of times. Even after driving miles and not touching it. There was a couple of times I caught it. You can somewhat feel it when it was half but still engaged. Funny thing is it's always the fourth gear also. My DD is a Nissan Frontier. Over 200,000 miles. No problems ever. Even on the original clutch.

I've had that happen, but it was due to the fact that I didn't fully engage 4th even though I thought I did. It went away after I shifted back into 4th fully and haven't had anything happen since.

I must have been tired and didn't realize it wasn't fully in gear. I was so tired and also preoccupied with the shifter slipping out of gear that I accidentally ran a red light too. I was stopped at the intersection shifting the car between fourth and neurtral repeatedly and then the only other car at the intersection (coming towards me from the opposite direction) just went through the light. I figured it was green, started driving, and realized it was still red and the other guy just decided to blow the light. Not good.

all's wll that ends well
 

sounds like a 1 time thing

hey, how good are the RE11s?

Too soon to tell (only driven 10 miles on them!) but I'll post a little review when I get more time with them. I'll be doing a track day April 3 so that should lend some good info as well. They're definitely no quieter than the RE050As but that's the nature of the beast with wide extreme performance tires.
