This sounds good on paper, but it is not the cause of notchy or difficult shifting in this car. AP1 and AP2 are Identical when it comes to shifters. But thats not the problem.

Dirty clutch fluid, poor rod adjutment, and a rusted input spline will always be the number one causes.

 

The U joints, I dont think I have ever actually greased those... were only done when the clutch was installed and thats been a really long time.

 

True, but there's always variables when it comes to notchy shifting.

 

How do you resolve the rusted spline issue? Obviously the tranny has to come off. Is this AP1 specific? Can it be removed with a wire brush then greased? How to prevent from returning?

Do not argue with Billman. he is the man. lol

 

Yes there are variables, greasing the shifter gives you about a 1% chance of fixing notchy shifting.

The s2k comes with no grease on the disc spline from the factory. If your clutch is original, and has many years on it, you can bet the bank you have a rusted spline.

Clean with a wire brush, and use a high-adhesive grease like Valvoline Cerulean. You can expect over 100k miles of wonderful, brand-new-car-like shifting.

 

Is there anyway to get to the spline without dropping the tranny?

 

No.

 

billman, do you ever adjust the master cylinder? if so, do you think theres a minimum requirement of pedal travel?

 

anyone can help reply to this?

i am having some notchy feel on my ap1.5
