This is a repost but i really need help... My 94 villager had it's battery arced bc of a loose ground to the engine block. After that the tranny stayed in high gear or constantly overdrive gear not sure which and quit shifting, or would sometimes decide it would shift hard once in a while. The O/D light wouldnt turn on or off so i replaced it the transmission computer. O/D now turns on and off now but the tranny still wont shift. When i turn the key on the O/D light blinks meaning the the transmisson computer has a fault code , but the check engine light does not come on so there's no fault in the seperate engine computer. Is there any way for me to retrieve it like retrieving the PCM fault codes with the check engine light? Does anyone know where to start? Thanks for your help. Im stuck?!
