I have the push button tranny in my 63 dart. I want to know if there will be an advantage to go to a later tranny, do a way with the pushbutton and go with a cable floor shifter. I have been told that stall converters are available for the later trannies and also that a lockup converter tranny can be used from a late model. any ideas and thoughts would be appreciated....GRT ps oops should have put it under the tranny section sorry its in the engine section
