Have an 87 T daily driver I recently aquired and am not happy with the stock shift. Shift fine, everything works as it should, but like the harder shifts. Was going to just put in a shift kit from CK performance, should I do anything else while im in there? This will never see the track or really any hard driving at all. Would I benefit from an upgraded servo, 700r4 filter, etc? Or should I jsut go with the shift kit?
