Hello all, I am new to the board and in need of some help.

I have a 1988 LX Convetible with a 2.3L and AOD trans. Myself and a friend are in the middle of rebuilding a 302 for this car, but I still want to putt around in it till its time for the swap. The front pump seal is bad in the trans and I have no idea how to replace it. I am a do-it-yourself kind of guy so.........HELP! anyone out there know how to go about this ??
