Transmission oil
What are you others using for transmission oil?
I have been using Shell Rotella 15w-40 white bottle, and recently switched to the Motorex CrossPower 10W-50 and the results are amazing.Smoother shifts and direct engagement .

Re: Transmission oil
ATF Type F for years now on all my bikes. It helps smooth out shifts, makes finding neutral easier, and it keeps everything sparkly clean inside!

Re: Transmission oil
Ok,thanks SS109
I will drain the Motorex in one of them and give the Valvoline type f a try.

Re: Transmission oil
Well, stick with what works for you. I've had good luck with it while others don't like it.

Re: Transmission oil
I bought 6 quarts of it last summer but haven’t tried it yet.
I will give it a try.

Re: Transmission oil
Dang y’all!!! I’ve been using cheap 10w40 dinosaur oil since in both our bikes since we got into this, now you’re making me curious about trying something more expensive!
Am having trouble finding N and hitting 4th lately, must be time.
Is this something that I can just drain the old stuff and fill the F or is there more to this?

Re: Transmission oil
Just drain and fill. At your next oil change all the regular oil that was left over will be flushed out. Give it a shot for one fill and see what you think. If you don't like it just go back to regular oil.MoonStomper wrote: ↑06:01 am Mar 28 2022 Is this something that I can just drain the old stuff and fill the F or is there more to this?

Re: Transmission oil
ATF-F is often times cheaper than regular old dino oil. Added bonus!MoonStomper wrote: ↑06:01 am Mar 28 2022 Dang y’all!!! I’ve been using cheap 10w40 dinosaur oil since in both our bikes since we got into this, now you’re making me curious about trying something more expensive!

Goes without saying, but make sure that it is "Type F". That's the only kind safe for wet clutches. Can't just dump in Mercon or something.

Re: Transmission oil
Type F is all I've ever used in my KDX. In fact it is specifically recommended by the auto-clutch mfg.

Please elaborate on what is meant by wet-clutches? I rebuild slushboxes, and I will just say right now that every clutch pack I have ever seen in any trans, was in fact, wet. And I also soak the new clutches before I put them in any build.
The principles from an automatic transmission to our motorcycles are the exact same. There is mechanical pressure, either fluid or spring, that applies pressure to a plate that pushes on clutches that are soaked in ATF/oil to steels that drive a hub.
I am just curious because I have been mixing dex3 and ATF+4 for years and I dont see why either of those, or any other ATF wouldnt function the same. If anything, dex3 would be a great candidate because it lacks a lot of the friction modifiers of modern synthetic ATFs.

Re: Transmission oil
This is the same argument as what premix ratio is best. You can use any motor oil or transmission fluid in your bike. Just make sure you change it frequently. I like ATF because it has better shear protection than dino oil, but mostly I use it cuz its cheaper. the so called energy conserving oils with friction modifiers will work fine as well. All that hype is about emissions, not friction. Run what you like, change it regularly, and worry about more important things...like is Juengling better than Stella (of course it is lol)

Re: Transmission oil
Wet clutch as opposed to a dry one, like you'd find on a Ducati or something. I've even seen some of those have their clutches open to the outside of the engine, so you can actually see it in operation while the bike is running.

Re: Transmission oil
Yes, Dextron, Mercon, ATF+4, Type F are all built for wet clutches. However, they do have different properties so your clutch will possibly behave differently depending on which you use. Type F is preferred in our bikes (and car racing auto transmissions) due to the fact it was designed to help shifts engage quicker in an automatic transmission (ie; less slippage) whereas the others are all designed for a smoother shift equaling more slippage.

Re: Transmission oil
So I guess I never looked too into what the basis of Type F was. Years of factory use, etc, until just now. I figured it was much newer than it was. But come to find out it was implemented the same year my mom was born. So thats a wake up call..SS109 wrote: ↑10:53 am Apr 30 2022 Yes, Dextron, Mercon, ATF+4, Type F are all built for wet clutches.

So yes, I agree it is probably the most best suited for these bikes. One could use dex 2 or 3 if felt the need to search it out, just because it has such a lack of modifiers in it, but Type F is readily available as said, I might even give it a go this time around.
For that matter, I like to use Dex 3 with a bottle of lubegard in my dodge builds. Stuff really improves shifts a lot, but it doesnt last half as long as ATF+4.
