I was on my way home today ( in my 76 monza, transmission is a standard 350 turbo) and i went to pass a person who was driving way under the speed limit. Car kicked down, i passed the person and rite as the car shifted it acted like i accidently put it in neutral however that was not the case. It will not now go into any gear ( D,M,L,R all act as if it is in park or neutral) ive never have any problems out of this tranmission until today. I check the fluid it is full. IDK WHAT TO DO MY CARS JUST STUCK ON THE SIDE OF THE ROAD TIL I GET AHOLD TO MY PAPAW WITH A TRAILOR :C
