Need help diagnosing noise...

[danjrusdug]

On my way to work yesterday, my shifter felt like it was going through heavy mud as I was going through the gears. On my way home, I heard a noise that sounded like a fan hitting something. The noise only happened when I was moving. At a red light the sound went away. As I shifted through the gears the sound progressed and was in time with the RPMs. Then the shifter got loose and I could feel the noise vibrate through the shifter. THEN, when I shifted into 4th, I heard a metal clang.

I took the back roads to keep the RPMs down to try to get home. On the last leg of my journey, the sound got louder and I was afraid my gearbox was going to drop out of the floor as I climbed the hill to my house.

My guess is the gearbox is shot. How do I know if it's the clutch doing this versus the gearbox? What should I be looking for? Or should I not look for it and just trailer the car to the garage?

Thanks in advance.

There are metal-rubber mounting blocks that wear out and then lets the shifter platform hit the driveshaft. Look underneath for a nice shiny ring around the driveshaft as a telltale sign.

....the shifter platform with it's supporting angle

arm have gone south. Do not drive till this is repaired.

parts may come entangled with the front drive

shaft quibo and causing more destruction, and possible DEATH

get under there with jack stands, a bright light, EYE PROTECTION,

AND LOCATE THE PROBLEM - ORDER THE PARTS.

LIVE TO drive another day.

Have you checked your flex disc? . . . I had a very similar experience with vibrations, difficulty shifting and intermittent clanging in my 1980 e12 that turned out to be a worn out flex disc. $30 bucks for a new one & less than an hour to change it out and it was smooth as silk again. Hope that your problem is something equally simple.

However, the guibo was replaced about 9 months ago so I doubt that is it. I'm 'gowing under' here in a little bit once I get caught up on emails and updating 2 documents. That's what's nice about working out of a home office whenever you want to!

I"ll update in a couple hours......

Guibo, driveshaft, tranny mount, shift connector all were intact with no excess play.

It sounded to me that something was loose in the gearbox and made a mess inside.

If everything external is in good order it is possible that the tranny shelled a bearing although sudden catastrophic failures are rare in my experience. We've got a dozen or so good used boxes. We can sort through them all and you can have the best one we can find for about $75. Could you feel any strange rotational movement through the clutch pedal as in worn out throwout bearing, damaged clutch plate etc.? Again if it IS the tranny it's really not a big deal other than getting the car here. Lemme know!
