back then everything was bigger, better, and just simpler
transmission now a days (automatics) are built more for driver comfort and reliability. Soft clutch material, low stall converters.. soft line pressures. All to make the driver of the car feel as if the transmission isnt even there.
It takes a lot of work getting our auto's to perform. The shift solenoid mod is a good start... I'd like to see the PCM side of things and see if theres a way to alter line pressure and shift points.
