If you have NO transmission fluid, that is very bad... transmission fluid lubricates the gears and helps to dissipate the heat. You might be able to get away for a little on a one speed, but if you have a two speed it will destroy it pretty fast.

Make sure that you use the right stuff, too. If its a puch it probably takes TYPE-F transmission fluid, but check around the net and see. You didnt say what kind of bike you have or I would find out for you.

Also depending on the transmission, you may be able to add fluid through the plug hole in the top, but be careful, as those tend to get really old and rot apart, you may end up fishing the plug out of the tranny with a needlenose like I did, and its not fun to do.

Again, if it is a 2 speed puch, fill it up to the drain plug hole in the bottom. I am sure someone around here can tell you how many ounces of fluid to use for what type of transmission.

2 speed is also type F, I own one and that is what I use and no problems

yep, thats where you fill it, it will come off, try some real penetrating oil, not just WD-40, then put a little muscle into it, c'mon I know you're buff

I am the old owner (not just figuratively speaking!).

I never had the screw out. I just unscrewed the bottom drain bolt to drain it out.

DO NOT RUN IT WITHOUT the proper amount of TYPE F transmission fluid!!!!

A suggestion:

I would soak it with penetrating oil like Liquid Wrench. WD-40 won't do you too much good. Soak it overnight. Wipe off the excess on the bolt and in the bolt slot and then use an impact tool on it. A handheld impact tool has various ends for it (Phillips and slotted in different sizes). You put the right tip in it, hold it very tight and then smack the top of the tool with a hammer. Make sure that you have the tool set for UNscrewing. I paid $5 for mine at the local discount auto parts store. Before buying one I'd check around to see if someone has one that you can borrow. Most backyard mechanics will have one for those stubborn bolts.

I hope this helps.

one last question, one ANY transmission fluid be better than none, until i find type F. because im having trouble finding type F fluid. all the specialty shops are far away. so for now (and only for a short time) could i just use another kind of transmission fluid?

i got liquid wrench and im letting it soak for a bit. i tried just spraying it, tapping, and then trying to unscrew it but it wasnt budging. i need some muscles. i'll try to get out to a walmart soon. im kind of limited on what i can get to because of my lack of vehicle while at school (which is where the moped comes into play as long as i can get it running).

i believe i have a onespeed. and im pretty sure its the only screw that logically makes sense to fill with anything. the others definitely look like theyre just holding the cover on.

You may also want to try getting it out with a ratchet. Get a 1/4" socket and then get a screwdriver bit that fits 1/4" (most bits are 1/4" and put it in the socket. The longer the wrench handle, the more torque you can put on the screw.
