I recently bought a '99 Camaro 3.8 V6 5 spd manual to use as a work car and for the most part it's been solid. The other day I was driving normally, and all of a sudden I started hearing a noise that sounded like a bad rod knock. Upon further investigation, the noise is coming from the clutch area. It usually only makes the noise above 2k in all gears, but is worse in 1st and 2nd, however, it will still do it a little bit in neutral too. My technical knowledge of manual transmissions is pretty limited so I figured I'd see if anyone here had any advice to get me going in the right direction. Someone has suggested that it could be a broken clutch spring, and from what I read, that may be what it is. I just figured I'd try to tap into the wealth of knowledge floating around here as well before I dug too far into it :thumbs:

Release bearing will normally only make a noise when clutch pedal is depressed. Once the pedal is released, the bearing should not be in cantact with the pressure plate.

 

You may want to look at pilot bushing (or bearing). Does this car have the hydraulic release bearing, does it use the slave cylinder with a push rod and fork?

 

Does it make the noise with the clutch engaged or disengaged?

 

It may be one or more of the clutch disk springs. These springs are the ones in the clutch disk itself and are not servicable. You would need to replace the clutch to fix it. Those trans are not that hard to pull to check. If you do replace the clutch, make sure you have the flywheel checked and resurfaced if there are any marks or heat spots on it. Also make sure you replace pilot bushing and release bearing as well.

In my experiences with release bearings its actually the opposit of what you said...its exactly like the op described...it rattles when its not in use, as when its being used....its hydraulic in this car btw....it has pressure on it and doesn't rattle. I have found that worn pilot bearings on these engines cause binding and sometimes the inability to get the car into or out of gear...

 

 

Either way...yeah, you may as well replace it all when your in there like you said...another part will only fail a month after and you'll have to take it all appart again. And clutch kits are cheap for these cars...and pilot bearings are like 17 bucks...they usually put a new one in there for you when you re-surface the flywheel.

is it an nv3500 or variant that came in these cars?

 

if so its a throw out bearing, even if its not you will find it getting to the throw out bearing which will shortly need to be replaced anyways. Parts are really cheap, its the labour that costs...

No its a Borg-Warner trans.

 

Yeah, real cheap....like under 300 bucks.

Clutch is under 200 bucks, throwout/release berring (slave cylinder) pick what you want to call it...is around 50.

 

most machine shops charge like 25-50 bucks to resurface the flywheel...or you can buy a new one for 50-80 bucks.

Pilot bushing is about 5 bucks.

 

Job is simple on an f-body...bleeding the slave is the hardest part....it can prove to be a PITA

 

Oh and get a bottle of blue loctite for your flywheel bolts...

      AFM Experience

      By Grumpy Bear · Posted

      Question @diyer2 on this line if you please. Are you saying the shudder is the system turning on and off at the frequency of the shudder? Guess I'm asking if you are saying you have seen it do this with the bi-direction scan tool in graph mode? If so have you been able to discern the 'trigger'. Something is telling to cycle rapidly.    My truck just started doing this recently. 197K on the clock. My response has been M5 anything under 55 mph. I treat it like a lugging stick shift. Gear down and let it spin a bit. Engauge M5, then tow mode and then M6 lets the trans stay in 5th but the AFM is active. Smooth like Skippy.    My thought was that as a machine ages the friction gets lower and as the system is load based, the lower friction would allow it to turn on at ever lower rpm until it reaches the lugging point. And yes I am ignorant of any minimum rpm requirement for the system. If you know that would be useful information.    As you know I run a Scan-Gauge II which allows me to watch the On/Off of the signal to the VLOM. While in the shudder mode I'm not seeing is cycle at that frequency or at all for that matter outside the triggers @newdude posted a few years back. Now is it possible that the refresh rate isn't fast enough to catch it? Maybe. It is why I asked my first question about graphing and trigging parameter.     As we have observed from members here the failure point is all over the map miles wise as you note yourself in your opening post. That by itself begs a few questions like fellows that comment on these lifters failing even after the system has been disabled. Long after. 😬   https://www.enginelabs.com/news/tech-tips-replacing-ls-active-fuel-management-lifters-with-melling/   The Gen5 lifters operate the same as the LS versions. In fact they are the same lifter.    https://www.enginelabs.com/tech-stories/sorting-out-gen-v-lt-lifter-failure-with-a-simple-valvetrain-fix/

      14-18 Sierra 1500 Heated Steering Wheel Help

      By SwitchBladeSierra · Posted

      UPDATE 2: Steering wheel control backlights and control of the cluster can supposedly be achieved by adding a wire to pin 20 of the cluster and tapping it to pin 2 of the main clock spring harness. I'm going to give it a shot - will update

      Seems to be Missing a lot of Updates

      By newdude · Posted

      GM Global A pickups 2019-2022 can do OTA programming for the radio.  GM VIP (GM Global B) can do OTAs for almost every module on board.  So a 2022.5 and newer pickup can do OTAs for recalls like the 2.7 fuel flow recall.  EVs get OTAs that improve one pedal driving, radio issues, HVAC issues, updated battery management software, etc.     So age of the vehicle/what GM electrical platform its on will alter what amount of updates can be pushed on OTAs.

      Upgrade to a 2026 AT4 with the 3.0L Duramax

      By Blade8971 · Posted

      Thank You.   So far my new ride is making me look like a genius for going with the 3.0L, as my first fuel refill occurred over three weeks from when I took delivery.  This engine combination is very amazing.  So far no issues and had not done a regen yet.

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      I am curious as to how much fluid you put back in the transmission ( assuming you had replaced the filter to compare to my findings ) and then went through the process of warming up the trans before pulling the check plug to drain out the excess and if you measured how much came back out.    I just found it surprising that some claimed a certain amount less fluid being put in and then draining some back out. The attitude of the truck as per if the surface is level and how the trucks stance is would make quite a difference since the check plug is right at the front of the transmission.
