I recently swapped an H22A with a manual transmission into my 94 Accord that was once an automatic. I haven't runned the car out on the streets yet due to the clutch not shifting smoothly into 4th and 5th gear--it keeps grinding. Any ideas on what I am doing wrong or should do?

 

bad synchros on the tranny? were you assured that the tranny was in tip top shape before buying? 5th gear synchros go out a lot on accord and prelude trannies.
