1998 Dodge Intrepid 98 Dodge Intrepid ES with Slapstick

Have a problem with a 98 intrepid es with slapstick. Just replaced the windshiels wiper pump and now I have a problem with the transmittion I think. The first time we drove the car after the pump was replaced and noticed that the only gage on the dash working was the tact. No speedomitor, no mileage indicator, all boxes lit on gears so had no knowledge of whether the slapstick was in 1st or anything. Then the check engine lite came on and the car would not come out of first gear. Insteadof trying to drive to the nearest Autozone we changed out the input and output sensors on the Trans. Engine lite is now off but we still don't know what gear the car is in the mileage indicator still reads the same mileage as when we first started driving and still in first gear will not shift up. Was wondering what could be wrong now. Would it now be the transmittion range sensor or the shift selinoid. Sorry about the spelling
