Installed Used Tranmission Installed New Frt Pump Seal Before Installing.
Same Problem
Anyone Have Any Ideas What Might Be Wrong. Torque Convertor Was Changed Also

Its 4T80e. So you must have a Deville Concours with a Northstar V8, huh? So if I understand, your leaking transmission fluid (red) from the bellhousing area? It has to be the torque converter seal then.
