The output speed sensor is located on top of the transmission output shaft, this will send speed value to the transmission control module (TCM).
The vehicle speed sensor is installed on the differential of the transmission, and sends speed value to speed gauge on instrument cluster.
Check also IAC valve and look for vacuum leaks using an hand tool gauge(Vacuum Gauge and Fuel Pump Pressure).

The problem is AutoZone. Stay away from that place. I once worked there and was amazed by the number of returns. They sell low quality parts, most of them rebuilt and listed as new.
The best of the low end parts dealers would be KOI, NAPA, and Carquest. All others blow chunks. Else, just go to the dealer.

Replace the transaxle or see if it can be rebuilt. Those transaxles have incorporated electronic solenoids that can fail causing the codes to appear as you described. One thing you might check prior to getting it rebuilt or replaced is have the computer checked and check all of your wiring connections. Anytime you have a wiring connector on the exterior of the vehicle you can get corrosion issues it may be simply cleaning the connectors, placing dielectric grease on them and reattaching. Before cleaning any connectors always disconnect the negative battery terminal.
