Alright,


So I am going to explain things in a four day breakdown:

Day 1: I remote start my car before work from in my house. 5-7 minutes later I get near it and hear a familiar rattling from the tranny. I get in and push the clutch down and it goes away. I take my foot off the clutch pedal and it doesn't come back. Yay.

Day 2: Same thing as day one, but instead of just making a sound, the car shakes a little too. But it goes away once I press the clutch pedal down and let it off. But the worse thing is that when I shut my car off, go inside and come back, it does it all over again. Rattling sound, shaking and then goes away when the clutch is disengaged and re-engaged. Drove it as little as possible.

Day 3: Car really starts to shake alot while making that sound. Also when I disengage and re-engage the clutch(this is all done in neutral) it doesn't shake but makes the sound.

Day 4: This is today. Car shakes and rattles all the time it is in neutral with the clutch engaged. On the way to work it has no problems while in gear and moving. Did notice it was a little harder than usual to downshift while coasting(the anal bastard in me always downshifts through the gears in stead of straight from fifth to first). On the way home from work it was still the same until I had to exit from 494 onto 52, I had to nearly force it into fourth from fifth with the clutch disengaged but it popped right into third from fourth seconds later. Did notice that it was shaking for the first few seconds while upshifting and after gear was selected and engaged. Then when I got to my street and at a stop sign it practically told me "no" to going from third to second, but went perfectly into first from third. But when I left the intersection it shook like a mother until I shifted into second. But slid right back into first without any vibration afterwards while I pulled into my garage where it now sits.

So it has gradually gotten worse but it was willing to cooperate sometimes and not other times.

I recently installed a ACT 2600 and XACT flywheel with a new OEM throwout bearing about 1500 miles ago. The tranny has had a new input shaft bearing installed also. Another thing of interest is that about a month ago I had the fluids changed to a redline mix while replacing a broken output shaft, and since down shifting into first at been difficult while moving.

Monday I will be looking at it myself, and any and every piece of advice will be greatly appreciated as I want to make it to Mayhem. If needed I would even been interested in accepting paid help on Wednesday for assistance with this.

Help a brother out.
Thanks in advance.

Yeah....quit using Redline. It is a GL-5 spec fluid which our trans's are not friendly w/.

The MT-90 and MTL is a GL-4 spec thats way we use them. And you might want to check and see if the flywheel is loose, thats what it sounds like. Or a spring broke out from the hub of the disk, that happens everynow and then with NAPA disks, but its an ACT disk so I dont know.

The Redline gear lube we used to get was GL5 spec. But anyways messed up cv joints in he axle will usually cause a very nasty vibration while accelerating. Might wanna check those as well. Also check and make sure the intermediate shaft didn't com loose fom the block. Being now you say it shakes in neural kinda throws it off from being a trans problem...

Broke discs usually wont cause any vibration. ACT discs break all the time as well. I've broken a few but never had any vibration from it, just usually wont let you in gear

I doubt the disk it broken. Maybe a spring or something though. When I shattered my disk, the car ran fine until I tried to put the car in gear.

So I figured it out. Being the sweet install techncian I am I decided to either not torque down most of the tranny to block mounting bolts or they wanted to back themselves out. Either way this once again proves the point that I should not be allowed to work on cars... Go me. :headache:

Do you have both of the dowel pins in the tranny? If you don't the tranny bolts will work themselves loose. Don't ask me how I know :P

I am pretty sure they are there, the tranny is at QPR right now, I will probably have to have them look.

Thanks for mentioning that, I knew there was something I needed to remember to check.
