I just recently reinstalled a d16a6 and si tranny into my 91 CRX SI, the motor was blown, but I reused the transmission. The motor runs pretty good and it seemed that the tranny did also. I was pulling it in and out of the driveway today, and I went to go get on it alittle and I heard a clunk, and now the car quit moving, now the gear won't go into gear, any gear. It seems that the clutch release arm is frozen and won't move, the clutch pedel and shifter in the car seem fine, anyone have any idea what happened and how I can fix it please let me know. You can also email me xx1loudmontexx@yahoo.com, thanks. The most I was reving the car to was 2500.

 

Something similar happened to me after a swap...

except after the 'clunk' it was stuck IN gear. I still don't know what the f*ck happened, but i had to tighten the clutch cable WAY down and then it was fine.

Have you tried messing with the cable yet?
