The transmission may develop a harsh shift condition with the Check Engine Light on and fault code P0717 stored. This is commonly cased by a failed input speed sensor (ISS), located inside the transmission. The wiring at the sensor may be found damaged. If so, the sharp edges near with ISS wiring should be filed smooth to protect the new speed sensor wiring from damage.

Same thing, hard time shifting into gears, sounds like its racing, odometer and rpm sometimes work most of the time not. No solution yet. Was told that I need a new transmission after putting in transmission fluid because problem was not resolved. Im getting a second opinion and asking what the code/s are.

Was going down hwy and it started to jerk a little almost bogged down, and after I came to a stop at stop light and began to accelerate the transmission just sounded like it was spinning and not engaging or something // after parking an turning off engine for a few and restarted it engaged and pulled off but after take off would not change gear and started making the spinning noise again. so now it is sitting in the parking lot at the local station..
