Manual Transmission Fluid Type

I hate digging up old threads, but as I am the OP, I guess I'll let it slide :hi:

I'm finally getting around to changing out the manual transmission fluid and can't find the capacity ANYWHERE. Even the owner's manual doesn't list the capacity as it says it's a "Lifetime Fluid." I know I just need to fill it until it slowly drips out of the fill hole (being level of course), but for purchasing purposes, how much does it take?

I'm beginning to feel some "notchy-ness" in my 1st and second gear, so I'm going to replace the fluid next week. I've heard of people using Royal Purple and saying it is a bad choice, so I'm looking to use the tried-and-true Redline fluids.

Here is my question. Some people recommend the MT-90 (along with pelicanparts.com) while I read a lot of places that say the 75W90 GL-5 Gear Oil is correct. The Redline application guide recommends D4 ATF and doesn't even list the MT-90! :facepalm:

What have you guys had success with?

yes sir that is it number ten so it's for cooling the power steering fluid
thanks for the help first time I've ever seen transmission fluid in the power steering thanks and sorry for the bother
I've seen trans fluid being used to swell up the seals and gaskets.

No bother. Glad we could help. Yes the E46 uses pure ATF for the power steering. Recommend Dexron III or VI.


As for people saying you might have an auto, please don't take offense because we've had posters make far dumber comments than saying they have a manual when they really have an auto. lmao. Only reason that came up is because you insisted it came from the transmission.
no trouble just the transmission fluid leaking out at that spot had me a little puzzled thanks
the power steering calls for atf
No ****, I guess I learned something new

Indeed. It just so happens that cars with automatics have a small cooling block near that area as well that circulates ATF and it has the same type of connectors on it even.

Buy two quarts. It takes something like 1.5... Be sure you remove the fill plug first. That way if you can't get it off you don't have a dry transmission you can't drive with.
I think it's around 1.1 quarts; but there's no chance of under or over filling. You just fill it till it comes out

Buy 2 quarts

Cool. Thanks for the info guys! The reason I ask is because the Pentosin MTF-LT-2 comes in 1 liter (litre??) bottles
