I have a Milwaukee, cordless screwdriver, model #6546-1. It's a two speed
screwdriver. You can see similar ones listed he

I had a small bit stuck in it and in trying to remove the bit, I partially
disassembled the transmission thinking I could push it out from the other
end. That was of no help at all. Eventually, I was able to dislodge the bit
and reassemble it. But then the bit would not turn even though the motor
would turn. To make a long story short, I then completely disassembled the
transmission again and after many hours of figuring how to put all the gears
back in, I got it to work. However with all the handling of the gears, much
of the lubricant came off and the gears now whine when it's in use. What
kind of lubricant should be used on these gears?

Thanks for your reply.
