I guess this is technically a "swap" issue. I'm having a hard time finding information on what other manual transmissions I can use in a 99' Civic Coupe EX with the D16Y8. The transmission makes a grinding noise going through 1st gear. What I want to know: I have a manual trans from a 93' Civic EX with the D16Z6. WILL I BE ABLE TO USE THIS TRANS in my 99'? They physically appear to be the same, same mounts, etc. Do they use different spline axle shafts? Are the clutch and flywheel sizes the same/interchangeable? Will I have to use the 99' VSS and will it fit in the 93' trans? Any help is greatly appreciated! Thanks!
