High Speed + cold = kaboom?
It was like 24 degrees out today, being idiot I am, I get in my car and decide hey I want to feel that cold air power. Car was dead cold, oils still thick what not. Drove like 100 yards, then pinned it. Once I got to 120 I put it in sixth gear and just held it there cruising. Long straight stretch of road.
Anywho, I heard vibrating like mad, thought it was just ice throwing a tire off balance. So I kept going. Turned radio down and realized it was coming from the car itself.
I pulled over and first thing I did was put it in neutral. Then try to put it in reverse. Won't go! It's a m6 btw. Then tried all six gears, no luck getting in any of them. Was going to get out of car to check shit out make sure fluids aren't flowing. But when I had it in neutral, let clutch out to get out of car it started to grab, as if it was in some gear. Shut car off, get out check, no fluids.
Then I just chilled for a bit, got back in car after letting shit chill. Put it in reverse, got it in reverse, let clutch out, didn't do shit. rpms going up to 2000 me still not feeling any drag and clutch is all out. Push clutch in, got it in first, then up to 4th and crawled home.
Before I got out, I put it in neutral and let clutch out, it was still grabbing like it was in gear.
Oh, and the sound it was making sounded like someone using an exhaust pipe to play drums on. Actually same sound my drive shaft made when I snapped that off last year as it turned and beat against the exhaust.
Any ideas what is wrong? Tranny was apart just 40K ago to replace reverse gear/syncro. And car was perfect before this. No issues.

Sounds like the trany is hosed to me.. Beating on ice cold equipment is always a bad idea..

No question about it: High speed + cold = Kaboom.
I don't know what could be wrong but with my 98 (M6) when it gets below 50 the tranny doesn't like going into reverse. I have to go thru 1-2 to get it to go smoothly into reverse.

It seems like your clutch is out or a broken TOB could cause issues. Pull the trans and see what's going on clutch wise and trans wise. Should let the car warm up before you hammer on it.

When you say you couldn't get any of the six gears, do you mean the shifter won't go into gear, or the shifter moves into gear like normal but the car doesn't move??
This problem sounds like something is really messed up inside the transmission.

Shifter would not physically move into gear...even with clutch down and pushing hard. But drive home it didn't slip and clutch felt the same when I let it out to start movinh

Ouch! I had to re-read the first post. I started to think a clutch spring or part of the pressure plate gave out. Hopefully it's a small fix.
And no more cold driving. Let the car warm up from now on.

Between rents car and bro's I haven't been in a rush to fix it. But taking it in tomorrow. Yesterday I decided to take it for a drive just to see what's what, as I did manage to drive back home after it happened.
Get in, start it up. Car in neutral. Let clutch out, I hear that nasty grinding and grabbing in neutral. Every gear change sounded nasty with hints of grinding. Babied it till it was warm, under 30mph driving. Then I decided to go out of town with it. About 50mph in sixth with 3.42 gears, so low rpm, the noise was really noticible. I would best describe it as imagine someone taking a nail and non stop scratching back and forth on a piece of flat stock carbon steel. It was constant, but if I let off the gas and allowed it to coast, it went away. It was loud when it did it though. Decided to try and give it half throttle. Thing shuddered like crazy but never put the power down. Freaked me out so I came straight home.
Oh, and reverse remained the same, let clutch out and it wouldn't even wiggle the car. And I just had entire reverse gear replaced 40k ago. Syncro's, the works. Brand new everything for reverse.
Oh, and clutch fluid level was perfect. Pedal pressure is fine.

Dang, that sounds bad. Something must be coming apart inside the transmission.

I'm gonna guess and say key ways, and/or synchros..?
