okay,

So yesterday I dropped two tannys and installed one into my 87 n/a

Everything works.....Except,

Now I have this funny vibration. And this weird sound.
A howling sound. Yes you can definately hear this sound.

Ever been in a car where when it picks up speed the stereo kind of mimicks the pitch of the engine speed?

Well its that kind of sound/vibration.

I filled the tranny with all the fluid as specified by the manual.

What did I do wrong? And does you shifter rod get hot?
(sounds like the **** e-mail everyone gets)

Is your shifter hot? And if so, how hot?

 

It may be your pilot bearing.Or your throwout bearing.I'm leaning more towards your pilot bearing.

 

Okay, that's a good suggestion.

First, when I rebuilt the engine I made sure to get a new pilot baring for the eccentirc shaft.

now here's the weird thing.

When I had both trannys out side by side my original throwout was about an 1/8 inch difference (more) in thickness than the one I was about to reinstall.

Because I rebuilt the motor in mine and got the new front, rear transmission seals and new throwout, I figured I should use one I installed during rebuild, even though both of them were pretty much new.

Would a 1/8 difference in the throwout bearing thickness between the two thowouts cause this type of problem? Is that possibly why my original tranny gradually bit the **** can?

holy ninja crap, I don't want to take the tranny out again.

 

That could be a possibility,the clutch may not be fully disengaging,therefore allowing for the destruction of the syncs.The throwout bearings should always match the original.

 

my tranny howls at idle and at all gears except 4th. push the clutch pedal in, howling stops. i've read this is just the sign of a worn tranny.

is yours doing the same?

Templeswain, when you put in the pilot bearing did you drive it in about a 1/4" past the bevel and install the pilot bearing seal? If you did the top of the seal should be at the bottom of the bevel.

 

Beat me to it John. Yup, when I push the clutch in the howling stops. I discovered this last night.

 

Yes I did do that.

But now I'm begining to think that I may have damaged the pilot bearing like a total retard.

I didn't have anyone to help me reinstall it so I was basically tricep extensioning that thing in there.

Its entirely possible I damaged the bearing on the install even though I was as careful as possible.

Whoops.

 

The pressure plate I got was also brand new and has about 10,000 miles on it now. But it was a thick plate much thicker than the one I replaced.

I think you totally right about the SYnc because it like to grind a little bit in reverse.

And like I said, I may have damaged the pilot on the reinstall.

I was careful. But I fear that maybe I was about as careful as a blindfolded Mountain Guerilla opening a box of cheereos.

 

Spunks,

What can I do about this? I don't want another crappy tranny.

Please please don't tell me I have to pull that back out of there.

Alright, I'm over it.

Tell me what I should do. All suggestions appreciated.

 

i don't have any ideas, but i'd like to hear how you fix it. i know mine's just worn...it's got 220k+ miles on it.

What do you mean "you did a tranny swap". Did you put your trans back in the car or did you put another one in? Are you sure the trans you put in the car is good? Did you rebuild the trans?

Rob

 

I put another one in. the one I replaced was a bitch to get into second gear.

Now the one that's in the car is great, just funny noise and every once in a while it will grind slightly when I put her in reverse.

Here's an Idea:

What if I take the pressure plate off and go get it machined so that its not so thick and beefy?

When i replaced the pressure plate during my engine rebuild I was like, 'whoa this thing is much thicker then my old pressure plate.'

Would machining the plate make it easier on the tranny. BEcause currently I have the clutch cylinder maxed out on its travel where it connects to the peddle. And the clutch still engages about 1/4 inch off the floor, like right off the bat.

Although I don't want to take the tranny out, I could probably do it in my sleep now.

 

"When i replaced the pressure plate during my engine rebuild I was like, 'whoa this thing is much thicker then my old pressure plate.'"


Another question. Do you mean pressure plate or flywheel?

Next time you put a pilot bearing do this... Put the bearing in the freezer for about an hour. Make sure you use some vaseline on the inside of the shaft. Cooling the bearing makes it so very slightly smaller and makes installation much easier. Then use a rubber hammer to get it into the shaft and then use a socket that has the same size diameter to drive it in the rest of the way.

Oh get a pilot bearing puller to remove old one. You can "rent" them from Autozone for free... about the only thing Autozone is good for imho.
