I drove out to Philly this weekend to visit my girlfriend, who is going to college there for the semester. Its like a 300 mile trip there, 300 miles back. Car ran PERFECT there, not a flaw. Parked it in the parking garage for the weekend.

On the way home. About 150 miles into my way home, im in 6th gear doing about 80ish? All of the sudden I hear this terrible noise coming from the transmission area. It almost sounded like someone was dropping a fist full of nuts and bolts into a empty pan, while dragging it on concrete. I know its a weird description, but thats the best way to explain. Now my car, ONCE before, threw a hissy fit and wouldnt go into 6th gear, so I thought maybe its just the gear. Go to throw her down into 5th, and the shifter wouldnt go past the nuetral area. As this is happened, it was making that "Grinding" noise it makes when someone new at driving a s stick is pushing it into gear without the clutch in. However, I had the pedal TO THE FLOOR. So I moved the shifter left and right, to assure im in nuetral, while it was still making this sound, I slowly let the clutch out and the moise goes away. However, when I tried putting it into 5th, then I let the clutch out, it shot the shifter back down and kicked it out of gear. So then I pulled over, glanced over the car, and got back in it. It was ok going through 1-4th, then it didnt want to go into 5th. I got it back into 6th gear.

So now here I am on the Turnpike, 6th gear tryin to keep up with traffic. Every time I would have to decelerate ( Note: NOT braking, just not accelerating, as in letting off the throttle) The car would make some type of faint "metal tumbling" noises in the tranny. Id give it gas, it would fade away. However, every time I gave it gas, if I wasnt SUPER easy coming into it, it would make some weird *** noises too. So then 6th gear started to get even noisier. I tried to downshift it into 5th, and it was like I didnt have the clutch in, it started grinding and shot it into the Nuetral spot. However, The clutch was to the floor, and the clutch IS fine. It is not the clutch.

Now I'm almost home, about 20 more miles away, and I start getting into more residential areas where you are using 1-4th only. I shift it into first to pull forawrd to a toll-booth. As I shift it in ( From a stop ) it was fine, I roll forward, push the clutch in, and am braking, but the shifter is still in gear. It continues to make this terrible noise like someone is forcing up on the hsifter, trying to put it into a gear without the clutch in. However the clutch WAS in, and the clutch seems to function fine?

Now the only way that it is ALMOST normal shifting ( As in wont make noises and pop right back into nuetral, sound retarded and making loud noises like grinding, or droping nuts and bolts ) is if I double clutch it. Like Start out in first, shift to Nuetral, let clutch out, back in, shift into 2nd. clutch out, and hope it doesnt make noises and **** up. What the hell can cause this? And as soon as I start to decellerate, it goes right back to making slight, but bad noises, like metal scraping metal or something.

My transmission has only 15,300 Miles on it, origional. The fluid was fine earlier in the summer when I checked it, and it never leaked a drop. I NEVER pound on it. I never downshift it hard ( As in no downshifts that will throw me over 3500 RPMs, in fact, I usually will shift into nuetral and just use my brakes cause brakes are cheaper to replace than a clutch ). You oculd pretty much say my car is babied. I have NEVER, in the 3300 miles I've put on it, ground a gear, missed a shift, did anything stupid that will mess up trannys, no powershifting. The car RARELY sees abuse. What the **** could be causing this?

My dad suggested that tommorow in the aylight, check my clutch fluid res. and see if maybe the Slave Cylinder **** itself or was leaking? And if thats fine, im checking the tranny fluid level now too ...

 

im having the same kinda problem with my car i someone told me it might just b the cat i don't know yet though haven't checked it yet

 

Come on guys ... Someone on here has to know about a M6. In the milage I put on this car, its usually babied. However I dont know how bad it was beat on for the first 12,500 miles it was driven. I bought it after that. But even so, right now its only got 15,XXX on it ? I dont see how a Tranny can just go while your driving already in gear, but what the hell ? Someone PLEASE help me. Im clueless as to where to start. Clutch fluid is good btw.

 

Not sure what happened to your M6, but you may try posting this in the Drivetrain Forum for more responses.......sory I don't have advice, but someone over there probably will.

this might not be it..but..when i broke a spring in my clutch..it did the same damn thing....every once in a while..it wouldnt go into gears..made the same damn noises...and then it would go into other gears...like it kept changing its mind...as the spring pieces were getting logged into the PP fingers. Best bet would be to take it apart. And btw....it happend outta nowhere...i wasnt beating on the car at the time. But thats what it sounds like it is..

 

that noise could be all the peices flying around in there.

 

Sorry Man,
Sounds like you broke a syncronizer or blocker ring on 5th gear and the metal peices are getting into the other gears carried by the rotating fluid.
You will have to pull the transmission and either tear it down youself or bring it to a shop for repair.
