IDK why I haven't posted here, I apologize for this long post but I need some help!!!
Hey everyone...
Yesterday (May 13th) i ended up changing out my transmission with the one that i bought from MR 325 ("Matt" on R3v)..
I bought it ahh seesh idaknow like in january??? Im unsure exactly when i bought it but its been awhile and I've been saying i would put it on, but anyway!
Along with a new Sachs 3 piece clutch kit, i replaced the Rear main seal (crankshaft seal) on the engine...
So other than taking too long with this procedure everything went well, until i rolled the car off the lift... The trans feels like crap, i can barely get it into gear... First off while up in the air i put the car into all gears and they engaged smoothly so i thought i was in the clear... I then lowered the car off the lift and tried to reverse it out the garage. The car wouldn't go into gear.. i could click it over to the left but as soon as i push up to engage reverse it feels so tough like there was a barrier. (Im thinking its not the trans but I seriously don't know!!!:confused:)
I eventually got it in reverse and drove it around the parking lot, but all gear engagements are rough and difficult, i basically have to double clutch every gear. There also seems to be excess vibration (never had much before) which I'm going to try and solve by replacing my flex disc (guibo) and center support bearing (CSB). I did mark the drive shaft and put it back the way it was when i took it off. And the clutch pedal does feel soft and i didn't bleed the clutch. (update [may 17th] I bled clutch car still doesn't shift smoothly) I was told this should be the problem with my gears not engaging correctly.. Does this sound right? or is the transmission just not in good condition? any info on the new vibrations? could it really be both the guibo and CSB cause they are mildly worn and not torn up, but i never had vibrations prior to clutch job and trans swap period, now I do when I let the engine wind down on its own while slowing to a light or stop...
One more question... Can/How do you adjust the clutch? (I've been told, there is no clutch adjustment since it is hydraulic, and is self adjusting) [Learning is fun!:cool:]
Another update [May 18th]
Today while driving i kinda felt a shaky feeling that felt rotational.. I started to think maybe i didn't torque down the flywheel well because it felt like the winding down on the engine while coming to stop seemed like a wobble...
anyway tomorrow i shall fix this!!! I hope! (doesn't seem to be loose i wiggled it but didn't have a clutch alignment tool so i didnt get to check the actual bolts)
Oh i forgot to mention when i was bleeding my (CSC) Clutch Slave Cylinder the thrust adapter.. fell out.. and didn't feel so secure when i pushed it back in. should i buy a new CSC?
Another update [May 19th]
While in first gear and my foot pushing the clutch all the way down, my car creeps forward before i even let the clutch out/engage... The same happens when I'm in reverse, the car will creep backward while the clutch pedal is pressed all the way down.
What can cause this? How do i fix it?
Could this also be the reason why my car doesn't go into gear well?
Another Update [May 20th]
So last night...
I Dropped the transmission and inspected the clutch, you can rule out the possibility of putting in the clutch backwards..
I replaced:
Flex disc (guibo)
shift fork
shift fork pivot ball
shift fork spring
But after all was said and done, I put everything back together and got in my car... just to notice something went wrong, again...
Both clutch pedal and Brake pedal are very stiff. (i bled the clutch and nothing changed there but the brakes felt less stiff.)
But, when i start the car the clutch pedal pumps itself rhythmically along with the spinning of the starter/flywheel...
Now what could this be.. what should i do? what could it be?
On another note,
I've noticed that the transmission that i just took out of my car, which was working fine (except for popping out of first gear) before the new clutch and different transmission, has a smaller input shaft and therefore uses a smaller inner diameter input bearing. While the transmission i just put in has a larger diameter input shaft, which requires a larger inner diameter input bearing. I want to know if this could be a problem, i'm sure its not, because either way the bearing fits right in, I'm just asking because maybe something is different somewhere else that may not be obvious, and that could be causing the problem.

Could be your clutch plate is not sliding on the splines when the clutch pedal is depressed. If the splines are rusty or have some rough edges, the plate will not slide and will remain pressed up against the flywheel, eventhough the clutch is not engaged. If you are going to pull the trans (again), also remove the clutch plate and make sure it slides freely on the input shaft. 2. There should also be some kind of adjustment on the slave piston. Just make sure it is almost snug up against the pivot arm, allowing only a few mm of travel at the pedal before contacting the pivot arm (the one that has the throwout bearing at the other end. 3. Did you replace the pilot bushing and is it the correct bore for the new input shaft?
