Hi my name is Austin, im from san jose california. I currently own a 1978 280z as well as a 1993 240sx, and a 1995 240sx. My problem is with my 280z. I think its the transmission but Im not a mechanic so im not sure. Basically my problem is whenever I smash on the gas the rpms shoot up but the car doesnt accelerate as it should. Any ideas as to why this is happening?
