My transmission will not shift into 3rd gear.It is an automatic with autostick and we've replaced both the input and output sensors on it.It will go in every gear,drive,reverse etc.,but when I go down the road it shifts into the first two gears and then hesitates and slips back down to 2nd gear.

Your car is going into limp mode. The computer is causing the to happen. The problem will need to be diagnosised .
