I have a si civic transmission from an 99-00 civic si. After putting in a gsr shifter my 3rd gear starting grinding at certain rpms, but doesn't grind if I double clutch. This has happened to me with a previous civic after installing an ebay short shifter. Also is happening to my friends del sol with a b&m short shifter and gsr tranny. Is ther anyway to fix this problem without changing syncros.
