I have a 2000 Z24 with an automatic. it has an auto trans intercepter. car sat for 5-6 years with the only tranny movement being pushed.
anyways I recently tried driving it and it doesn't shift until you let off the gas. its extremely sluggish as well. engine & trans has only 58,xxx. I was doing like 5 grand and only doing like 40mph (til I let off then it shifted. but didn't pick up speed) HELP! any ideas? the O2 senser wasn't hooked up. could that be the cause? odd but maybe..? HELP please
