So I have a 92 integra gs 4sp auto. I feel the interior is a little dull and thought about getting some stuff one them being an aftermarket shifter. The problem I have is that the oem shifter has a button which allows you to switch from s3 to s4 so you can get to 4th gear. After market shifters don't have a button to allow this so my question is, if I were to install an aftermarket shifter would I not be able to use s4 anymore? I appreciate all feedback. Thanks again
