How to change your Transmission and Differential Fluid - FT86SpeedFactory.com 

Also it's not necessary to remove the metal skid plate. You only need to remove the 10 millimeter bolts to take off the soft black part right under the transmission itself.

Notice ft 86 didn't ever make an annotation showing they don't care maybe?

Nah they don't give a fuck so they ain't gonna put an annotation.

Wow good catch man! wtf on their part

Vichet Meng and also they didn’t shuffle through the transmission to replace the old ATF with the new ATF

I hear you. I have a gravel driveway. Makes it really difficult.

If you cant get a lift, try to see if you can get a set of quick jacks. Its the next best thing.

Hi are you still alive?@@djsnaps12

86 and BRZ have torsen gear diff, not clutch type lsd. It doesn't require friction modifier like a clutch type does. You can use regular gear oil in a torsen like in an open diff.

tonyzase you say it does not require the friction modifier, but would the friction modifier help with the differential life?

I don't think there is going to be a difference in longevity between the two oil. But i think that friction modifiers can change the torque biasing of the diff. Running a thicker or a thinner oil grade will also do. I personally would put the same oil in trans and diff and save money over buying two differents oil.

From a past Subbie dealer we always added friction modifier additive on diff change.

Don’t use that on your diff use 90pa . I blew up a diff with that gear oil

Correct !! 👍🏼

David Sio the transmission washers can be reused. The diff washers are crush. So they should be replaced.

No

You can use the oil from the video for the rear but not in the trans, automatic needs automatic transmisión fluid

Owner manual says GL-5

yeah, I am looking for that right now and not having much luck

@@ashg129 hi, were you able to find the information you were looking for? Thank you and hope you reply

Hey guys sorry I'm late for this video but did anybody ever find out for an automatic car how often should the transmission and differential oil be changed?

vision1707 hey, so I’m a senior tech at vavoline and I searched up service for my car and it said that transmission should be done every 135,000 miles or 60 months. As for the diff it’s every 15,000 miles or 15 months. Also want to point out that all the info from valvoline is straight from Toyota so there the correct time intervals.

vision1707 btw I drive a 2017 Toyota 86

They won't make a video on how to change spark plugs because it 's such a pain in the #$%@. there's a guy on you tube who did the spark plugs changed on youtube.

They made a video

Yes your right if that’s an automatic. What he did was for a manual transmission car. I did the same thing with my girlfriends WRX same fluids in transmission and differential

This aint fkn automatic trans smh

I believe the LS is for differentials with clutches.

@@lordvesel the official Service Manual from the manufacturer says that we need an oil with "LS" written on it, even though the gt86 has a Torsen Limited Slip (LS) Differential without clutch ... But since neither the oil manufacturer (motul), neither the car manufacturer (subaru/toyota) explains "why" ... i don't know ...

Two are enough...one for the bottom of the diff and one for the bottom of the trans.

@@mosesnzusi5658are they the same bolt? or are they different sizes/thread

They don't answer questions it seems

TheBadassOne17 i would Also love to know

I do mine every 30,000 -35,000 miles !

TheBadassOne17 I just hit 25,000 miles and I'm doing mine this weekend.

ohhh shit im almost 44k, should I be worried?

RUZBAY86 Check your owners manual, and service records if applicable. Better to do a change and not have to worry about it.

No! You need a automatic transmission fluid! Auto trans use a hydraulic fluid, manual use gear oil!

@@blakeorsinelli5638 OK so then what specific ATF do you need for an auto trans on this car? How many qts? How about the rear diff?

@@a.o.647 Rear diff should be gear oil. The automatic transmission is just whatever atf you want to use. Look up the owners manual for capacities. Just depends on what your doing and how much you want to spend for what brand you buy

Motul sells atf fluid. I ordered the motul gear oil as seen on this video for the rear differential, then moguls atf fluid for trans. Also picked up 0w20 royal purple oil for that fluid change too. I spent a lot of time trying to find the most recommended fluid for the auto trans on this car

@@oof578 how many bottles did you use

do you have an aftermarket air intake, sometimes the induction sound they make will sound like a wining sound

Ashark7773 Gaming just now seeing this. But it’s all stock

Did you ever find the problem, dealing with that rn

it’s your throw out bearing same thing happened to me

Wheel bearing

No

@@russellesquivel-barker2270 thanks?

Dru670 every 30k

Dru670 it’s at every 60k my dude, he explains when maintenance are due on an other video ✌🏼

You’ll need to buy a pump. You could pick one up from O’Rielly’s

I was wondering the same thing. At least he didn't put 300LS in the trans.

Alexander Zamora Nope, not a clutch type lsd. It's a torsen

From what I've read on forums, it must be the LS, some people experienced weird noises and sensations when they changed it with a non LS.

Everytime you have sex. So about once every 4 years.

After every 40000km or whenever the fluid turns dark

60k

He says it in one of his videos, usually whenever the fluid looks dirty replace it.

Magnetic plugs usually come with their own crush washer

For the differential? Yes

Please note GL-5 is a newer standard and is not required by all 75w-90 fluids!

Following ***

No and it doesn’t say that, it says it contains both of them but you can choose either the trans or diff, and if you want both then you need 2 separate orders, one contains the trans and the other the diff

The comment was 3 years ago but oh well might as well

Motul is not the only option, but it's what we choose to use in our cars. Here's the rest of your options - www.ft86speedfactory.com/drivetrain-41/oil-137.html

i bought 4 quarts of motul 300 a year ago but never got around to doing the fluids it should still be good right(was stored in a cool dark place)?

Ft86speedfactory

lol yes u can still use it, its not milk u dont have to wirry about it going out of date

lol ya i just got worried cause i heard somewhere that if they sit for a while the additives gets separated from the oil

its what your car comes with from factory

from ebay

link is in the description

It’s used in manual transmissions and differentials. It’s been through millions of miles of successful race testing so I wouldn’t worry about using it on both.

@@doanjn Yeah, but it is still suppose to depend on the type of differential. Your answer does not mention that. Racing with what ? an aftermarket locking diff ? the optionnal torsen ? The manual is pretty clear about that : same oil could be ok for open diffs, but lsd specific required for torsens (though dealers would use open diff oil in torsens in France).

Crush washers “crush” when being torqued to spec, so it creates a super tight seal, but when you remove it it’s not like a rubber gasket that rebounds, it’s broken and does not hold an air tight seal anymore. However people still reuse their old crush washer if it’s in good condition

@@justinlam6402 Thank you for the explanation

If it doesn't leak and the teeth are in good condition then you don't have to if you don't want to but it is advisable to replace the washers after two or three uses.

Moses Nzusi thanks!

Yes...but procedure and fluid are different

The procedure is pretty similar only that you will refill through the automatic transmission's dipstick and keep on checking the level until it's enough. However, DO NOT USE the fluid you see in this video. It is not made for automatic transmission. Refill with a fluid called ATF, Automatic Transmission Fluid, usually pink when new.

@@mosesnzusi5658 the automatic doesn't have a dipstick buddy

@@mosesnzusi5658 pls tell me where it is for the life of me I cannot locate it

@@oof578 Under the bonnet...just search on youtube...it's a hard one to spot

@@mosesnzusi5658 it’s literally the same process just instead use automatic trans fluid

No. Use ATF.

Bro Im having the same issue

@@Jay10292 I did a search and found pics and how to do it on a forum. There's no video for the automatic but its a much more involved process than a manual

i want to know too

I think so because my auto doesn't look like that

Get ATF motul 300

Dude at Subaru dealership gave me gear oil which confused the hell out of me but ATF it is

@@quarkymatter ATF is Automatic Transmission Fluid. Lol gear oil is for manual trans and differential. I used motul 300 ATF for my auto trans FRS and motul 300 75w90 gear oil for the differential.

@@oof578 exactly why I was confused because I told the guy I needed transmission fluid for my automatic BRZ and he still gave me gear oil. It was a close call lol
