I just purchased a YS1 tranny, I want to throw it in my 90 integra while retaining clutch, flywheel preasure plate ect, ect. Question is, Will my stock clutch spline up fine with the YS1 tranny? I mean do ALL B series trannys have the same size splines in the imput shaft?

 

90-91 same spline
92-93 is different then your clutch

In your case you cant use the same clutch

 

ohh......... yeah ive heard about that but i thought it was just a rumor, so are all YS1 trannys the same spline as 92-93?
