Thinking again about the noise in Bobs tranny.

[tery]

Hey folks, the snow is almost gone here so I'm about to get back to it with the Shos. Someone had posted an idea about the random clack/tick noise I'm getting at idle on my manual tranny 95..They said something about if the noise goes away when you put in the clutch, it means that??? and that's where I lose the memory and I can't find that thread response. What does it generally mean if that random clack/slap/rattling noise stops when the clutch is help in, you can hear the noise pretty good on the vid I uploaded. Here is is again,
It goes away when the idle is up and/or goes away when the clutch is in..
Also, if you just let out the clutch slowly without a lot of rpm, it pops of out 1st gear with a nasty feel. If you give it 2grand rpm or more, it works fine, and if you drop the clutch like popping it at a light, it stays in gear...???
Does this seem like a throughout bearing problem. I thought someone had said that if there was a ceramic one in there, that they were rattly and loud sometimes

I suspect you have multiple issues, Terry.

The rattle that goes away when the clutch pedal is depressed could be a bad throwout bearing, or the cable could just need to be adjusted to get out the slack. The clutch cable is adjusted by pulling upward on the clutch pedal. Try that and let us know if it changes.

The popping out of 1st under light load is almost certainly an internal trans issue - the 1st gear syncro / shift collar is likely worn so that it wants to slip out of gear, or the shift fork is bent so that it does not go all the way engaged in first or something like that is going on inside the trans, imho.

Thanks very much Fred, last year, I was having trouble getting it IN gear and noticed that there was quite a bit of slop at the top of the pedal and the
'self adjuster" wasn't working right. I worked on it a while and was able to get the sloppiness out so that it is tight at the top of the stroke and then had no problem getting into 1st. but that fix had no effect on the random rattle noise either way...so I'm thinking like you said that the syncro or the fork is the issue. Could either of them have/produce that noise?? Like if the fork was bent and not resting against could it make that rattle noise??

Some people on the forum said that the ceramic bearings were just noisy anyway, and the guy I bought it from didn't know if it had one or not....and so I'm thinking maybe that the random rattle is not be related directly to the 1st gear issue. It never pops out of any other gear of course and the whole thing is pretty loose really, you can pull it out of gear with no clutch as long as you're off the gas, but I think that is characteristic of any old/worn manual tranny. Another couple weeks and it'll be warm enough here to do some more serious investigating. I'm feeling pretty trusting of the guys/shop who did the timing belt on Babe green since it was done very well and so I'll have them drive Bob blue around next month and see what their opinion is without tearing into it..

What is that nice blue car with the black bra above you're name. Did you buy another car? I kinda decided I have to sell some of these cars this summer. I bought a 2002 F150 over the winter and it's just ridiculous trying to have all these cars at once. I'm thinking to take care of any major issues they have and then keep the best one, which actually is ginger that had the hole through the floor, because the motor in it only has like 125k, whereas the others are between 180 and 210. THe problem of course is getting over the fact that I won't get the money back that I put into them, which is about 3k. I had a fantasy about taking three of them to the dealer at the same time and getting them to take em in trade in on a new or newer SHO, but then that is getting strapped to payments. ouch

There's a couple nice older SHO on craigs list that have been sitting there for a month or two, so I am thinking that not a lot of people are buying 22 year old SHOs. But they're really too nice to just ,,,oh ****, I might just have to keep em and get a property with a quonset hut on it. Then I could buy the other two on craigslist...ummm..

a worn shifter fork can cause a rattling noise, but generally not loud enough to be heard except on careful examination. the ceramic tob do tend to rattle, but there were never that many cars that had them installed.

any manual trans can be pulled out of gear with the clutch engaged as long as you are off the gas - all disengaging the clutch does is take the torque loading off the gearset so it can be shifted and if you are off the gas then there is no torque loading then either.

so if was not wanting to go into gear because the clutch was not disengaging all the way due to mis-adjustment of the cable, then the shift fork could easily be bent such that it does not go all the way into gear, thus causing your issue of popping out of gear.

the blue car in my avatar is one from about the middle of my list of SHOs in the signature - it wasn't that nice and I just did the needed maintenance and sold it again (but that was a number of year ago).

As ever, thank you again Fred...In your experience, is ir very unusual for a shift fork to get bent, or is it something that commonly happens in SHO MTX trannys>>/??Thx,
Tdrry

these trannys do not shift well to begin with, so it is unfortunately not uncommon for a shift fork to get bent. generally, that means the fork needs to be replaced, because they to not seem to hold up if bent back, and you need to take the trans apart to get to that point anyway.

in my for-sale thread I have some tranny parts if you need some.

THank you Fred, hopefully I WILL get to that point this summer...
