alright, recently I just had my car converted from auto to manual

after driving it around for a bit, it seems that i am having some weird problems. I really dont have any major knowledge about transmissions, but I need to know what is going on so i can tell the ppl who are going to fix it.

Problems:The car will sometimes NOT go into gear easily at all. I will sit in neutral and it refuses to go into first or second or ANY gear.

When I finally FORCE it into gear it has like a spinning grinding sound going on. It sounds like the the gears in the transmission are engaged, but they are still grinding, but not extremely loud, but enough that it cant be normal.

Now this doesnt happen all the time, but enough that its a real problem. Sometimes I push in the clutch and it will go into every gear just fine, but then other times it just does NOT want to engage at all.Its about 50% of the time for each

The other thing (if this helps) if I am riding the car fast and changing gears in higher RPMS, like over 5K or so (like it was doing just fine when it wasw an automatic) then it will NOT let me go into 3rd gear w/out forcing it hard

This CANT be normal

Sounds like your not getting enough pedal pressure.

I assume you used a steel braided line from the master cylinder to the slave cylinder?

I had simular problem, but I had 5 speed (no auto swap) the stock damper on and clutch bleeding was basically impossable.

So I pulled off complete damper loop, the clutch hard line and ran a steel braided line from master cylinder to slave cylinder, bled the system about 5 bleeds and then voila perfect shifting!

Or it could be more serious like the transmission is going bad, or throw out bearing is going bad, or could even be as easy as a silly monkey did the swap wrong or messed up someting

Update:I had this nagging feeling that the car was revving too high and u know how if you are in second or in a higher gear the car wont let you get into 1st gear? well my car is idling at about 2K RPM. So i fixed it up this morning again so it would rev lower, at about 750 RPM like its supposed to and it seems to be engaging fine now, but ive only driven about 5 miles so far and im not completely sure if that is what fixed it since it doesnt happen ALL the time.

Could this really be the problem?
