Have a 90 crx with b18c swap and cable tranny...when i start up and go not a problem in the world....once i start driving and it warms up i guess, for some reason my third gear grinds up and down shifting.....never in any other gear just third...and my only thoughts are that if the syncro or 3rd gear was gone why only after im driving for a bit?


any ideas??

 

syncromesh!!!!!!!!!!!!!!!!!!!!!!!!

 

you could have a broken shift fork...

 

Nothing is broken there is no reason why it is fine for till it gets warm or hot and then starts clicking just in third

 

i had that problem in my DA i just put in GM syncromesh and it went away.
goodluck
