Fluid to use
There is somewhat of a debate regarding the correct transmission fluid to use for Tomos A3 engines. The contenders in the debate are typically Type A, Type F, 10W30 oil, or Spectro Golden Gear Lubricant from Heeters. All of these options have received good and bad reviews from someone at some point, and that can make it hard to choose. Type A is harder to find -- most auto parts stores won't have it (people seem to have the best luck finding it at grocery stores, truck stops, and gas stations). Type F and 10W30 are cheap and readily available, and the Spectro Golden, if ordered online, will almost certainly be more expensive. The manual recommends Type A or 10W30, but people have had success with all of these options. Search the forums if you want, or just pick one and try for yourself. If you like it, keep going with it. If you don't like how it works, go to your next choice. (It would be really cool if we could get some reviews or positives/negatives for each of these options in here...)
How to change
- Find the drain bolt/plug on the bottom of the transmission. If you were to draw a line from the carb straight down through the engine cases to the ground, the bolt should be on the bottom of the engine cases somewhere around where that line would be.
- Get a jar or some sort of fluid-containing receptacle ready.
- Start unscrewing the bolt/plug and be prepared for the fluid to start pouring out of the hole
- Let the fluid drain. You can tip or shake the moped a bit to make sure you get all the old stuff out. (Also, doing this while the engine/fluid is warm makes the fluid flow better).
- When all the old fluid is drained out, screw the drain plug back in, being careful not to strip the hole out.
- Unscrew the fill screw (on top of the transmission) and the level screw (on the side of the transmission).
- Add whichever fluid you chose to the fill hole until it comes out the level screw hole. Once it stops coming out the level screw hole, you can put both the level screw and the fill screw back in, and you should be good to go.
- ALTERNATIVELY: The manual recommends using 220 cm3 of transmission oil. It really probably is best to measure, but if you don't want to, then the level method should be okay.

How to change
To change gear box oil you drain the plug or bolt at the bottom of the transmission. The bolt on top of your transmission is for filling. There is a phillips head screw on the side unlike the allen heads that actually hold on the gearbox cover. Once you have drained the old oil, and bolted back on the bottom plug, fill new transmission fluid until it leaks out of the side where you have taken the phillips head off. Fill the machine on level ground, sometimes a wood block can be placed under the front tire to make it sit level. Many recommend being very careful NOT to strip out the phillips head on the side, as it is not very strong metal. Use an appropriate sized phillips screwdriver.

How To Change
Refer to the A35 instructions, everything is the same. REMINDER, when taking off any of the bolts holding the gearbox cover on (which is not necessary when changing the transmission oil) please remember to use metric allen keys or else you will strip the bolts.
