For you CD4E atx experts out there,
Does anyone know exactly what triggers the flashing O/D light? I suspect it is the torque converter lock up slipping. Is this correct? Why does it not set a PCM code? I recently spent $2K on a tranny rebuild and I still get this error. The tranny shop says they will take care of it, but I really want to understand what is going on. How is it that they can essentially replace the tranny and I still get the same error? Anyone that can shed some light on this wouls be greatly appreciated.
