There is a jingling noise from the transmission ONLY when the clutch is engaged. It's an s80 transmission. I have it on a b18c and it has the lsd. I also have an ACT Street Disc assembly and ACT Pro-Lite flywheel. Both bearings in the transmission were replaced and it still makes the noise. Anyone had this problem before?

A loose throw-out bearing can make a jingling noise when the clutch is engaged. Does it get quiet when you just rest your foot lightly on the clutch pedal? That puts a small load on the T-O bearing which pushes it together again.

If it's a tranny shaft bearing, it wouldn't quiet down until you disengaged the clutch by pressing the pedal all the way down.

 

The throw-out bearing was replaced. The noise STARTS when the clutch is engaged.

 

i was gonna say throw out bearing but it seems you know about that.

did you replace it with a used one?

the last time i heard jingling from a transmission was in my eclipse 420A.....

it followed by the throwing of gears all over the road.

 

yea it was replaced with a new one. my mechanic says it might be the clutch disc... im waiting to hear what he says after he drops the trans again on monday.

When it's engaged the crank & tranny are locked together so the pilot bearing doesn't spin.

You're left with the tranny shaft bearing, but you replaced them. Well, 2 of them anyway... Usually you can hear them coasting to a stop if you disengage the clutch quickly at idle.

 

Hmm... I'll ask about the shaft bearing and see if he replaced that. I actually don't remember him telling me about that. Thanks.

Pilot release and throw out bearing.

Typical h-t ***-- tries to be a smartass and prove someone wrong.

Pilot & throw-out bearings aren't really 'in' the transmission.

 

ok then im sorry. i consider them part of the transmission.

 

if its only when the clutch is engaged, its not a problem within your gearbox as the mainshaft isn't spinning. Usually a noise with the throwout is constant, I would think maybe a spring in the pp? Start there.

 

The bearings inside the transmission can go loose & rattle. I like to tell people to do this to tell the difference between t-o-bearing vs. tranny bearings...

Idle in neutral, clutch engaged (pedal up). It's making the noise, right?

Press the clutch pedal just a little, take up the slack but don't press it down. A loose throw-out bearing will get quiet just by doing this.

Suddenly & quickly disengage the clutch (push the pedal quickly to the floor). It takes the tranny shaft a second or 2 before it coasts to a stop. You'll hear a noisy tranny shaft bearings as it coasts down.

Ok here's the news...

The springs on the clutch disc are all loose and move around which is causing the jingling noise. So my ACT pressure plate's fine, I just need a new disc. They put in a cheap Competition Clutch for now. I'll eventually get a better disc, maybe a Spec disc tho. It should work with the ACT pressure plate right?

 

Don't mix and match clutch parts they don't always work right together. Glad to hear there is people like jimblake on this board. Anytime one of these posts come up you get the crowd that says throw out bearing when its clearly something else.

 

Yea I'm going to have to look into this farther-- interchanging clutch parts. I've heard different stories from different people. Kinda hard to know whats actually true.

 

I've personally seen interference between disc hubs and pressure plates before. I also ran a mismatched setup before on my own car. It worked well, but never felt right
