i have a 94 z28 lt1 auto trans car has gone to limp mode before i tried to turn around in road not much room when i hammered on it i lost all forward gears i drove home 15 miles in reverse it always went good before any help or ideas would be great thanks

 

check to make sure the filter didnt drop down and your sucking air. if not then the trany is busted. did some reading and found that the sungear can break doing the same thing your seeing.
