it grinds if i get my rpms up and shift it grinds it does it even when im driving normal i have to leave it in neutral for a sec so it wont grind

I am also having this problem with cy crx. It has a b16 in it. It also has a short shifter. It does this when the RPM's are kinda high. My old crx had a d16 in it and it shifted fine untill I put on a short shifter. It then started to grind when I tried to shift at high RPM's. Is it the short shifter or what?

well just to let you know mine does it sometimes as well.. i have just kinda gotten used to it.. even my buddies car with a rebuild d series si tranny grinds when he throws it into 2nd.. so could just be a common thing?

change the tranny oil... gm syncromesh...its some good shit...
my dx used to do that...after i changed it with that it wouldnt grind anymore...
as for my si tanny...she is toast...i need to rebuild it, someone who had the car before me must have been really hard on it...

Yeah your synchros are going.. nothing you can do to stop it except some syncromesh oil.

You can try some GM Synchromesh, but really you probably need some new synchros. If you do get around to rebuilding the tranny, scuf up the cones with some 180 grit (use a flapper wheel)... it will help bite the synchro teeth. Also, get rid of the short shifter... it will only kill your trans faster.

a short shifter doesn't kill ya tranny. go to gear speed for the synchros they will hookya up. and until then just use gm synchromesh.

Short shifters are a leading cause of rapid synchro wear. And yes, Gear Speed does have a good selection... they were the ones that gave me the tip on scruffing up the cones. I've been using their carbon synchros in a number of trans for a little while now, good stuff.
