Some snags with my conversion

Funny you say that, I forgot I had the quart size one that used to fill my ford trans years ago.... Oops... Yes I thought the fitting was a good idea and it worked really well.

Started the car, put just the rear in the air and rowed through the gears.

Weird noise on the passenger side, like something was hitting and went away. Put the car in the air and cannot see any evidence of anything hitting. Turning motor over with flywheel tool and can't hear or see anything. Very strange... Seems fine now but that does not always mean its ok...
