alright, on the way home from church, speed up to pass a truck, going around 65. the car is in OD and as soon as i give it some gas it acts like its in neutral. just free revs, i still have first and second gear, no problems whatsoever, its just as soon as the car shifts into third or fourth, no power at all to the wheels. im stumped, becasue the car still shifts by itself INTO third, but nothing once it gets there, any suggestions?

 

shift solenoids, bad clutches, TCC solenoid...just spitballin, some diagnostics would help to narrow the search
