trans clickty clacking, 'clunked' today stopped shifting, but...

[fleck]

hey guys, so a few days ago my transmission started to rumble a little going into first gear unless i gave it a good bit of gas. after a while it started clickity clackin, again going into first gear, sometimes randomly. there is also like a rubbing that goes away when i push in the clutch, had been like that for a while. today it finally CLUNK'd out on me and everyone said it was my linkage or syncros. my mechanic came to the scene, shifted it into reverse to a nice hard grinding sound. he can't figure it out though, it runs fine but on the way home it stopped me from shifting again until we let it sit for a couple minutes and went at it again. right now we're both clueless as to what it is. in october we did a master/slave clutch job, replaced the motor oil in the tranny with the proper ATF, and the mechanic that did that job said the clutch was indeed new and the pressure plate looked new and the flywheel looked good. the shifter has always been sloppy (but there are NO bushings where there are supposed to be) and shifting into 2nd without waiting a couple of seconds has always made that too-quick-shift grind noise intermittently.

we're gonna drop the tranny tomorrow but i'm wondering if anyone has any clues.

Sounds like it finally went south on you. The oil instead of ATF was somebody's bandaid to prolong its life.

Take the top off and look after you pull it. One of mine had impressive gear carnage, with chunks.

you talking about the whole tranny went south?

i just thought the guy used oil because parts shops mistakenly tell people that's what to use.

posting my trans problem from the 3.0 board on here...

hey guys i posted this on the 3.0 board but since nobody there seems to know i figured maybe a transmission specialist would be more likely to read this forum and drop me a couple of cents, TIA:

You have no "linkage". Your clutch is hydraulic. Also, having no bushings in the lower shift boot is no help. They should be in there. It sounds like you have air trapped in the hydraulic system. Try bleeding it before you do anything serious. Follow fastpakr's procedure, as it works well. Syncros will pick random gears, they don't all go at once. In addition, you could have a bad pilot bearing which would cause the rough shifts. Did he replace throwout and pilot bearing?

If the plastic shifter bushing are gone where do you think they went?

Or haven't you thought it through that far?

They fall intothe trans and get chewed up into smaller pieces by the gears, once chewed into those smaller pieces they can migrate with the oil to some restricted places inside the trans where they can do real harm....

And the thicker oil helps carry them along...

When you push in the clutch, the input shaft takes a few seconds to spin down and match the output shaft speed. So sometimes if the blockers, or syncros, are going bad they will grind if you try and shift to soon.

Thanks, where is fastpakr's procedure at?

Well, the trans work was all done after those bushings were already gone and I wasn't told anything by my mechanic about damage or debris found in the trans fluid (motor oil) or anything like that.

Would that have anything to do with these symptoms (the noise like there are marbles in the tranny)?

Also, something I forgot to mention is, after my mechanic got the trans to shift again, right before it died it started doing stuff like, I shifted to third and it was rough and it made a little squeek and a thump, shortly after it quit shifting again.

If you pull your seats out, pull the carpet back , then you can take off the access cover on top of the trans. Look in there with a light. Se if the teeth are chipped or anything. JUst look it over, im sure you will see something.

I have found several fragged transmissions that were "professionally repaired"
that had JUST failed after their rebuild...

Because the person rebuilding didn't clear out the plastic chips from the tail of the cluster gear causing the float bearing for reverse gear to self destruct from oil starvation.

This is often the caust of 5th gear float bearings and the infamous "pocket bearing"
inside the input gear.

the pocket bearing is actually pressure lubricated by a tiny turbine pump
on the input gear but that turbine pump feeds two holes that are
only 0.080" in diameter and are easily blocked with debris from
chewed up shifter bushings.
