watch the tranny oil

I'm new to mopeds and I'm the first to admit I have a lot to learn. I just learned something that I'd like to share with others as green as myself. When you get your new moped be sure to check the transmission oil, don't depend on the dealer or distributor doing it for you. My new Avanti was doing odd things with the transmission, jumping and skipping, so I checked the oil and found there was almost none in there. Added non detergent 30 wt until it ran out of the hole, and it's fine now. Lucky I had not done any long rides yet and only have 100 miles on it so probably no damage was done. Just BEWARE.

Re: watch the tranny oil

you were lucky. good advice to everyone. always check for transmission fluids (both for quality and levels). even if there's something in there, i'd say drain it out. you have no idea what's in there. and the oil costs less then $2 for a quart.

If you own a Puch, make sure you use "F" type automatic transmission fluid in your clutch/gearbox. Don't use Dexron! If you ride it on a daily basis, say for delivering papers or for commuting, change the oil once a month. I use a small rubber baby enema syringe ( don't laugh ) that I got at a drug store to fill it with and it works great. A quart will do about 4 oil changes.

Uh-oh! what will dexron do to a puch? I thought dexron was supposed to be pretty much universal.

Re: watch the tranny oil

Doea anyone know of a non-detergent sythetic oil I can use in my tranny?

I use Mobil ATF in my '98 Tomos. It is a Dextron III I believe. Not sure, but I know it is dextron. Will this harm the bike? It has 1,260 miles and I havent had any problems with it.

Hi,Ken! I've not seen any non-detergent synthetic,but if anyone makes it,I'd say it would be AMSOIL brand,because they are big farm suppliers.So if you must have synthetic that's non-detergent,ask them.All the big companies have what is called`TECH SERVICE' people who are their chemical or products experts.Make sure you ask for their TECH SERVICE expert.I run regular synthetic EXXON 5W-50 which is the consistency of 30-35 WT. oil and I never have problems with the Morini or Minnarelli engines.The 50 wt. side scares some mechanics away because they think of the old THICK 50wt. conventional oils.Those were lacking flowability.BUT the new synthetics have that rating because of their superior resistance to thinning out at high engine or tranny temps.I use 5w-50 synthetic winter and summer in 3 cars,2 mopeds ,and a backhoe,along with my mowers.That way I know that I'm giving my gearboxes and engines the best wear protection.

Re: watch the tranny oil

Brandon, at your first opportunity I'd go out in the garage and get that dexron out of it and put in F type transmission fluid, run it for a day or two and drain it and refill it again. I don't know what will happen if you use dexron for an extended period but I do know the manual says to use F type fluid. Brian

Brian,

What model Puch is your manual for? My Puch (1977 Newport (same as Maxi) single-speed) has a tag near the trans that says "use only ATF transmission fluid." Here's what I found after reading the transmission fluid bottles at the parts store:

ATF+ is designed for Chrysler transmissions.

Type F is designed for some Ford transmissions

Mercon III Dexron is designed for Chevrolet, Chrysler, Daimler-Benz, and most others exept Ford.

I know that Puch is a product of Daimler, so I'm guessing that the Mercon III Dexron would work. I don't know why Puch and Ford would be the only two to use one certain kind of trans fluid. Can you give me some more details from you manual? I think you might be missing something.

Thanks for bringing it to my attention, though.
