I got mine years ago at the local auto parts store. Most of the gear oil now comes in quart jugs that have a needle spout that you cut off like a caulking tube. Clumsy and messy affair if you ask me. | | | | | Joined: Jan 2009 Posts: 1,644 Shop Shark | | Shop Shark Joined: Jan 2009 Posts: 1,644 | Take a pc of 1/4 inch vac hose about 2 foot long and cut the tip off the qt. bottle of gear oil to go inside the hose tape with some duct tape than just put the other end in the trans hole and pump the oil in slowly,with bottle upside down. I just keep my tip like that because it will fit most qt. size bottles.

I have seen them that will fit both gallon jusgs and quart bottles. They have 2 set of threads in them. I do not recall who made them, but Speedway Auto Parts in Speedway Indiana was where i saw them.

I have filled it that way but I think the "preferred" way is to fill it through the fill-level hole on the passenger side of the case.
The grease fitting on the torque-tube "receiver" at the rear of the transmission was not for grease - it was for filling the u-joint ball (pre-filling the ball - the enclosed u-joint receives lubricant from the transmission. I recently removed that "grease" fitting and filled an sm420 through that small hole in the "receiver".
