Hey all! Thanks for all your help during the installation of my AOD transmission into my '67 convertible. Now that it's all bolted up, I decided to actually start the car back up! It started up fine, but after about 5 minutes there came a regular humming noise from the transmission. It increases in pitch as I press on the accelerator, and deepens in pitch when I put the tranny in gear. any idea what's wrong? I checked the clearance of the torque converter bolts against the backing plate, to make sure they weren't rubbing
