Getrag 240s and as I just learned recently 280s, and some ZFs used ATF. You are fine.

Done listen to those two, I have no idea that they are talking about or where they got their info but its wrong. We used a BG total flush machine at my last shop for years and never had an auto transmission break because we changed 100% the fluid. Sounds pretty stupid to not flush old fluid out when the old fluid is bad...

Edit: I see Andrew saw he was wrong and corrected himself but idk why CHIF thinks what he does.

That's what I thought, thanks.

So I filled it all up, and it started overflowing with like 1.8 quarts in it. I don't think that's normal...is it? It's definitely up to the fill hole, I checked like 5 times. Even got in the car and shifted around a bit and checked again (not that I really thought it'd make a difference).

Places that sell "tranny flushes" are full of crap and only ruin cars

There is another option, use a Universal Tractor Transmission Oil. Mobil call it 424, Caltex call it Textran Premium HD, Fuchs call it something really original like UTTO. It's generally a 75W80 but the big benefit is what's in the additive package. Because it's specced to handle wet clutches and combined trans, final drive and hydraulic systems it's really a substantial overkill for a fairly basic manual gearbox. The results are really good shift quality (cold and hot), low noise and very good wear protection. I've been running it for 50000km plus and does work much better than the specified gear oils or AT fluids. The average mechanic will look strange at the mention of the word "tractor" but any lubricant guy should be able to explain it better than I have.

the g240's may be different though, but i know that with a auto tranny you do not replace ALL the oil at once. and if this manual tranny uses ATF id think that that rule still applies. (because of the nature of the oil)

[Vivek]

It's not an auto though..?

[CHIF8008]

you usually use 2/3 new oil or something like that. been awhile since my auto tranny class. Places that sell "tranny flushes" are full of crap and only ruin cars

[Vivek]

Are you sure about all this? There was no sticker to never change it, and I've never heard that before. I've also never heard of not replicating all the fluid and I've looked through a million threads on this...you're scaring me :o

And andrew...no clue why but yes it uses ATF. What I drained out was pink and smelled like atf. And there's a bright orange sticker on the bottom that says something like "ATF-OIl ONLY!".

[5Toes]

Yeah drain bolts is what I meant, it was pretty obvious

Manual transmissions dont use atf I thought? G260's dont.. I know that.

ATF is no where near thick enough for a manual tranny. ATF is a type of hydraulic fluid, it is not designed primarily to lubricate.. like manual tranny fluid.

EDIT: well I find this weird g240s use atf. I was wrong

[Vivek]

So how is all old ATF better? Should I have mixed old and new (already drained it...)?

[CHIF8008]

oops its a manual tranny? it actually says to not change the fluid in manual trannys right on the side of them. i thought you had a auto.

and for your question. read what i put- all new ATF will tear up a old tranny/ shorten its life very quickly. ATF is very abrasive

[Vivek]

Huh? What's wrong with replacing all the fluid? And g240's (at least some of them) use atf. Mine had ATF in it.

[CHIF8008]

tranny drain bolts 5toes

hope your not replacing ALL of the ATF fluid. thats a no no. the new fluid wil act as sandpaper and tear up the inside of your tranny

[5Toes]

Wait why do are you talking about breaking tranny bolts free then post up atf pic???

[Vivek]

Nope. There's no need to. The PS fluid is just for the hydraulic transfer of energy assisted by the PS pump. The rack itself is internally self-lubricated.

At least that's what I've heard.
