Hello. I just purchased a 2008 Impala that is leaking tranny fluid from various locations. I replaced both cooler lines and fittings at the transmission, new gasket and filter kit, and a new fill tube seal/grommet. I still have a leak that appears to be coming from above and it's collecting on the pan gasket, making it appear as if the pan gasket is leaking. I checked the vent and it is open and working fine. I checked both axle seals and looked at torque seal through the inspection plate. All are dry. I put vehicle on the lift while running and wheels spinning, and no leak. It only leaks while driving/under load, with tranny at operating temperature. It runs down from somewhere, collects on the pan, and the aluminum frame behind the pan, and blows back on the converter, and most of the way back on the underneath of car. I can't tell where else the fluid may be leaking from and I'm wondering what other leaks are common on these transmissions? Thanks.
