Im new here, and here is whats going on. when i push the pedal im at 3500-4000 rpms, and going nowhere. maybe 20-30 mph. when trying to get on the freeway pedal to the floor, and no faster than 55. i have to let off the throttle and ease back into it to get the car to shift. is it the transmission or solenoids. any info is greatly appreciated. dont have the money to fix right now, but will after i get back from working in Trinidad, Africa, and Austrailia about 30-40 days. thanks
