My buddy was quoted $60 for the local Ford Stealership to do it, we did it for less than $15 in about 20 minutes.
I have a 5 part funnel that I got a wally world that has a long flex tube part that comes off on the bottom. That long flex tube attached perfectly to the top of the bottle of fluid. You screw the tube onto the bottle, put the bottom end in the hole, then raise the bottle up higher than the hole and squeeze. Repeat until fluid starts coming out the top hole where the tube is going in. cap it off, wipe it off and viola! your done.
