So from everything that I've read on here, it seems that after you drain it, you take the side plug out and fill until the fluid reaches the hole and put the plug back in. Just looking at the position of the side plug to the bottom of the trans, there's not a whole lot of fluid going in. The manual says 1.5 pints of fluid should go in, but that's for a 3-speed. It states a 4-speed needs 6 pints. Is there a different way to fill the 4-speeds? I can't see 6 pints going in from this plug....
