Once the car warms up the transmission starts shifting erratically and the speedometer stops working changed the speed sensor no difference. Any help would be appreciated.

Hello Bob,

This sound like the PCM is going out but to be sure here is a wiring diagram and a guide and a diagram so you check check the wiring to the PCM and the speed sensor, there is nothing in between the sensor wires and the PCM.

Please run some tests and get back to us so we can continue helping you.
