engine and drivetrain How to confirm transmission failure?

[TobyB]

Yeah, time to look underneath-

if the guibo- right behind the transmission-

and center bearing- about 2 feet behind, wrapped around the driveshaft-look good-

(you'll be able to tell if they've catastrophically failed)

the next things that pop to mind are the flange that comes out of the

transmission itself-

it loosens and self- destructs, and it's not visually obvious that it's done this, (and likewise, the nut in the center of the driveshaft can do the same thing)

or

the differential. The small spider gears inside are known for crunching themselves up.

Good news is that, barring the transmission output flange, the rest is pretty

easy. And not too expensive, if you find the parts yourself.

good luck, and if you jack the car up, do so safely! (search- there's a good thread)

I'm still amazed at all of the responses I've gotten- you guys are life (and money) savers! Don't worry, I'll jack up the car safely... which is why I haven't done so yet.

Just had my Guibo done. $40 for the part and 1 hour labor.

Just had my Guibo done.

Think of it as rolfing for your car

What do you mean by "the gears were slipping"?

[samsue2002]

By gears slipping I mean the engine seemed to be going faster than the the car itself could keep up with. I tried looking up signs of transmission failure and from what I read, slipping gears was what best described what was happening.

My dad's coming in town today to try and help me figure out what happened. I'm printing out all of these replies to show him and will update with our finds.

Thanks again.

I would figure you grenade'd a guibo. Or you did like what my buddy did on his jeep pickup and grenade'd a clutch (that was a story).

Nine times out of ten your tranny is fine. You can beat the living day lights out of the old 4 speed. They're a flat out tank of a tranny!

Investing in a good jack and set of jack stands is always a good thing. One of the first things I bought when I moved back to school this year was a nice jack. It'll pay for itself real quick.

Best of luck!!

hmm, wonder how the clutch is, too...

Let us know what you find!

I'm glad I read to the bottom before responding, because the condition described sounds like a worn clutch disc.

So, did ya'll find anything out?

I would like to guess the 4sp output flange stripped.

If thats the case... Here is one for sale here

Well....half a year later Dad was finally able to make the trip to my house with the new guibo.  Had to remove the muffler to get the drive shaft completely off to replace the guibo.  It was an excuse to rev it without the muffler which was a treat of course.  Took it down the street after it was put back together and it's back to normal...even after sitting outside for so long.  What a good little car.  Here's what my guibo looked like:
