@ 60 mph car shifts acts like it sifts to neutral then shifts way down when u barely lift your foot from the gas. @ 45 it seems ok but it really screws up when trying to pull a hill and it is trying to shift. seems like a common prob. fluid level is fine and the fluid looks good. the code it threw said that the solenoid is open.
