Shaking Issues possible Clutch Chatter

[moses_m]

My 69 bronco is starting to shake once I turn it on and leave it in neutral. The shake goes away when I press on the clutch. I have the explorer serp installed 2014 with the dampner dudes balancer and NV3500 transmission. What should I be looking for or checking?

Just starting to shake after things had been working fine all this time?
Strange that it goes away when you push the clutch. And it's a real shaking, not a simple vibration?
Very strange.

I'm not sure yet. Haven't run into something like that. Maybe someone else has some insight.
When the clutch pedal is depressed, the flywheel and clutch cover are still spinning with the engine. Only the clutch disc and transmission input section stop (or come close to stopping) their spinning.
Maybe the disc is deteriorating? Hate to think it's something in the transmission. Did you use the specific gear lube that's required for the 3550? Checked it's level and condition lately?

Just for our information, what else has been done to the engine? Is it a stock 289/302, or is it something else? (edit: nevermind. I see you have it showing as a 302)

Good luck.

Man, I’ve got that exact same issue! I was thinking maybe the flywheel or clutch came loose..

Hi, one simple thing to do is run it for a couple of minutes without the fan belt to eliminate the front of the engine stuff. Good luck

If it goes away when you depress the clutch, that pretty much isolates it to the throwout bearing/ clutch disc or possible pressure plate springs or actuating fingers I would think. Or could be something with the input shaft or bearing of the trans. Ken

Will check level and remove belt and start. Please refresh me which oil do I need.

I guess it started as a vibration but it now shakes when I start it. It decreases when the engine is warm.

Have not posted been running the last couple years trouble free.

If you can't find anything with the clutch, you might want to pull the pan and check the thrust bearing clearance.

I had a clutch that was acting strange, vibrating and then went away and then finally wouldn't work right. Ended up that one of the small fingers on the diaphragm broke off and finally wedged itself in the clutch and jammed things up.
Good luck, hope its an easy fix!

In case you do need new fluid, it's a very specific gear lube that was at first only available from Chrysler Corp (FCA now) but is now available from some of the aftermarket companies like Redline and others.
But whatever you use MUST state that it's compatible with the NV3550 specifically. Not the 4500 or any other gearbox. If it does not say for the 3550, try something else.

Good luck. Hopefully it's the clutch though. Sounds less expensive when you say "clutch" vs "transmission"!

Issue resolved transadapter plate that mates tranny and bell housing was not fully seated. Tightened all bolts on plate.

Let's hear it for cheap fixes!
