    Ok, the manual shows taking out the entire transmission, was just hoping to avoid that if at all possible. Is tha input shaft connected directly to the converter or does it slide off of converter and come out with the front cover??

    Cat d4d transmission input shaft seal replacement

    Well, got the seal out, and looking in there at the bearing it appears that the bearing is bad. Looks like it is missing about half of the ball bearings. Can a person remove the torque converter cover without removing the transmission or has this just turned into a major job?
