instead of dropping the whole tranny, is there even viewing area if I just unbolt and move around the pressure plate as needed to check parts? Maybe not the bearing but releasing tension on the PP may allow me to check if there is a broken ring possibly. I just can't remember how much room you can make by moving back the PP

Hi Guys!

Well my english is verry poor but ill try to explain as good as i can. ive had 2x broken Presure plates the last 3 days now and what i found out is that the Presure plate it self (the ring going where the clutchdisk lies in) it being hold up by 3 "arms" of steel theese failed in both my PP`s so check them out and see if anyone of them is bent. if they are bent then the PP is most likely touching the outerring of the PP hence the pedal gets stuck in the floor. this also couses a noise when the torqe is going to be absorbed by the PP itself.

Well my english do SUCK! i know ;) hope u understand what i meen. this can obviously be checked trough the inspektion window. If they are unnormaly bent u have a PP failure.

Regards

Hellström!

^thanks for the tip but all of them appear normal. BY the arms i guess you mean the thick metal strips attached with pins around the outside of the PP plate. I have a picture of one on the first page in the original post.

opened everything up again and ran the car with a stethoscope. Couldn't hear anything besides what seemed like fluid moving around and a constant tick noise throughout the entire engine/trans setup. I also think i have a very slight case of rod knock towards my #1/2 cylinders.

One thing i did find was my driveshaft has a lot of play in the center bearing. According to GaboonViper85 this is normal to an extent. I found i have about a .25 in of play only upwards direction. Also when pushed up with minimal effort it makes a clunking noise. Not sure how normal this is, input?

NEW: it appears on my 200 mile journey back to school last night (about 2/5 of the way home) I lost First gear in the process. My guess would have to be large metal particles getting caught in the existing gears causing the loud noises and violent vibrations. It also explains my inabililty to reproduce the noise.

Ill be flushing it out today in hopes it will last me an additional 300 miles. Hopefully the damage isn't too much to make it. I find it strange since its been rebuilt. My guess would be the combination of hard clutch and poor hydraulic system. From slamming the gear into second maybe the clutch wasn't disengaged enough causing first gear to be damaged.

Just cuz it was rebuilt that means nothing. You know, who did the work and was it good. Sounds like sourcing a new trans maybe.
