the car is a 99 si with a obd1 b18c1, the problem is shifting gears. when the car is off i can put the car into any gear at ease, but as soon as i turn it on its a bitch to put it into first or any other gear for that matter even reverse, and when ido get it in gear the whole car starts to shake real bad. what do you guys think it could be?

 

i didnt install the clutch disc upside down did you?

 

the disc cant go in backwards , lol. it protrudes on one side , and is flush on the other , it only fits in the PP one way. but its definitely a clutch issue id say. the vibration your feeling is the clutch grabbing the flywheel even with the clutch in. have someone step on your clutch and hold it while you watch the fork on the tranny , see if it slowly goes back even with clutch held.

 

i'm totally aware of that but, i have seen people do some stupid things

 

ok here is the update, i havent messed with the cluth or flywheel, but ths weekend the car was driving pretty good i could shift it into any gear even downshift when i wanted to, but after a few hours of driving around i felt the shifter kinda sink in and the sameproblems as usual started happening, so with this said could the shift linkage be the reason for the malfunction

 

how does the clutch pedal feel? could be a bad cylinder? maybe bad slave or master. have u tried bleeding ur clutch? give us some description on the pedal feel.

 

i had this same problem with my gsr also... it comes and goes away... then after couple weeks it just stop running cause my pressure plate cracked in half.... how this happen? i dont know

 

had this problem, turns out my clutch master was bad and eating up fluid

 

the cluth feels normal, the only thing that i can tell is off is the shifter

 

get under it , have a look at the linkage , have someone shift it around while your looking for play. gotta be a linkage problem.

your pressure plate cracked most likely cause whoever had it apart last , overtightened it.
