Sluggish and doesn't change gears when suppose to.
I have a 1996 J30. It's sluggish and
doesn't shift gears when needed. Could
this be the cadilyk converter stopped
Could be a damaged catalytic converter. Or it could be any of many other causes. If you have warning lights, have codes read to find where to look. Or better yet, go to a mechanic to evaluate. It might be a minor thing that's easy to fix. Or it might be major. Wouldn't knowing be better?
