I sent my OE pressure plate to Southbend be tourqe to 500-600 lbs ( not so sure about the numbers ), and also ordered a full face feramic disc.

Now, I am trying to figure out everytime i shift ( well, sometimes, kinda hit or miss) the dasboard shakes a bit and makes a thud sound like a have a solid transmssion mount. My transmission mount is rubber and metal so it is dampened.

And everytime i go reverse , my 1-pc driveshaft makes continous/multiple sound similar to an exhaust pipe hitting the chassis. I just took off the CV part of my driveshaft and I have enough slack and i don't think it is bottoming/hitting something. Driveshaft is straight and not angled when installed.

I suspect it should be the torquey pressure plate? Southbend guys, do you experience this? I don't this crankwalk BS, I had 120 miles on this engine and stopped driving it.


1-pc. drive shaft with enough slack on the CV when isntalled.

Will going back to 2-pc driveshaft gonna help? My 1pc driveshaft does not vibrate at all at high speed

could you maybe take a video of this? you sure its not clutch chatter/vibration

No clutch chatter... smooth engagement, no vibration. Shifts normal. But since it has retorque PP, I have to give some more gas before releasing the clutch pedal.

Thud sound/vibration on dash happens after I release the clutch.. most likely to happen when I shift to higher gear on lower speed. Like 3rd gear on 40mph or less.

I don't have a video yet but I'll post my first run on the build thread, make sure you turn up the volume, you will hear my dash.

I was thinking running the car without the driveshaft in my garage and see if the driveshaft is the problem...

will post the first run vid in a sec.

Not visbile but it happened on 0:08 on the vid you can see the camera shakes a bit.

ok I see what you are talking about. does not seem like a D.S issue to me at all. more like either internal in the transmission ot something in the pressure plate/throw out bearing area

Is there something to do with engine's thrust washer?
What do you think about the transmission, I shortened the shaft before installing it.

Here's R154 shaft and bearing retainer... see the empty spot?




And here's AR5 with R154 bearing retainer and there's no gap, you think it has something to do with it?

oh yeah I see what you mean. definatly possibly. these should be the same. even my v160 is like that

JesLet

If that's the case I might need the GM hydraulic throw out bearing.. like the 1UZ manual guys use

I PMd limequat and we'll see if he has the same issue... if that's the issue I will be converting to this:

GM slave cylinder or switch my PP to stock

Okay, I took off the 1-pc. driveshaft and ran the car in my garage up to 3rd gear and there was no vibrations at all.... weird thing is the engine didn't die when I left it in the first gear and released the clutch. I know the transmission is working because I used reverse and hear that whirling sound.

So you think i need a carrier like the OE 2-pc driveshaft? I'm willing to try to convert to 2-pc, I just want this car to be reliable as possible.

Is the purpose of that carrier to dampen?

Highly doubt it since I have a one piece shaft and I have no issues

I have different transmission though... well see.
