    03 330ci auto trans issue

    Driving down interstate and noticed blue smoke behind my car. Pulled off nearest exit and transmission was slipping,was able to drive it back home another cpl miles and trans fluid is def leaking out under the car. Is my trans fubard now or is there any chance of saving it? Codes are PO700 PO788 pressure accuator 2 and 3,battery voltage,supply terminal 87 po700 and po560,can abs/dsc wheels speeds,converter lockup clutch,excessive slip po740,p2761,po741

    Thanks in advance

    Sounds like a ZF with a blown pump seal. Can you confirm it is a ZF? Crawl under and look at the pan. Smooth pan = GM. Cross hatch pan = ZF.
