^^ yeah... i don't see it listed:

the 75W90 NS and 75W140 NS listed underneath are GL-5 type

 

I swapped mine - i guess its smoother .... I never shifted real rough but I guess it makes a difference from 3rd to 4th. Overall - from what I hear - its a good product.

 

you were right, my mistake.


I just change gear oil today. i didn't remove the sensor plug.
Here are the step after i put the tC on Jack Stand.

1) I loosen the Fill Plug first, (make sure i can fill it after i drain it)
2) then i took off the Drain Plug with a wrench. It took me a few try to position the wrench to make room. it is pretty tight down there.
3) Put the Drain Plug back on after it finish draining.

Then i use a long funnel.
4)Drop the funnel from the engine bay area.


5)Go under the car to put the end of the funnel in Fill hole.
6) Move the draining pan under the fill hole to catch the extra fluild.
7) After dumping about 2 1/2 bottle of Redline MT90. You should see the extra fluid come out. ( u can see it from by looking straight down from engine bay area)



Remove the funnel and put back Fill Plug.

 

One more thing,
DON'T OVER TIGHTEN THE DRAIN PLUG

 

Well I have my 3 bottles of mt-90 sittin here, but the dealer just told me that anything other than Toyota's own fluid will void the warranty. So I dunno, I don't want to void the warranty on my tranny, but I'd really like to have smoother shifting! Anyone else's dealership say no way to this one?

 

The truth about voiding your warranty
just change it...
^^ haha... ..... i did that too.... wasn't pretty to fix...

 

why would you tell the dealer you are doing this? is the dealer your mom or something...?

if you follow that dealership's logic, using anything other than toyota branded oil in your engine for an oil change would void your warranty...doesn't make much sense does it? thats because it's just not true.
the dealership would have to find the fluid as the cause of a problem...if you even have a problem.


just follow what i posted earlier in this thread to avoid problems...and goto a different dealer
also if you are unsure, please read the following thread:

Wow dude, did you have a bad day or something? You need to calm down and get off my back for real. Don't you have anything better to do with your time? I was merely stating my experience with the dealership which may be helpful for some people unlike your comments.

No, I didn't say hey momma dealership I'm gonna change the tranny fluid...wtf...I simply asked if they would do the work since the car was already there for regular maintenance. Whats the big deal? They said no, thats their policy and its not gonna change no matter what kind of motor oil justification you come up with. Its not my policy, I never said I agreed with them. Simply means I can do it myself or go somewhere else. Thanks for your overwhelming common sense though.

Nowhere did I say OMG this could void a warranty dont anyone do it!!! I bought the redline fluid for a reason, its gonna go in, just not at the dealer whos says they will void the warranty.

Please excuse me for letting people know that *most* dealership service centers will probably not do this fluid change with anything other than their own fluid.

LOL this forum is gettin so lame, no wonder people are leaving. And thanks for the link, really, how about you go ahead and refer yourself to some of the "people are a$$holes on here" threads.

Anyhow, nice write up Instigator. Its been very helpful to many people. Myself included as I'll probably do this myself when I get a chance. Have fun with that new STi! :D

 

my bad, it was late and i spent way too much time at offtopic's forums, some of the bad mouthing rubbed off on me, sorry dude, i take back what i said

but yeah, a toyota dealer will never use anything other than the recommended toyota fluids.
mt90 is a great alternative to the toyota branded fluid in your tranny right now. some of my friends have swapped for mt 90 and put 50k+ miles on the car, without any problems arising. it seems to be a safe swap.

but if you are unsure or have existing tranny problems, do yourself a favor and save your old fluid, that way there will not be any warranty voiding because of the new fluid

 

^^Hey no prob, yeah it was late and your post caught me on edge. I agree though, from what everyone has said so far, the mt90 seems to be a great swap. I'm anxious to get it in my car. Your idea to keep the old fluid is def. a good one, I will do that just in case. But yeah, its all good, happy moddin bro

 

i'm just wondering for anyone that has already done this swap, who has put the most miles on they're car since then
some of my friends have done this before, but none of them own tCs

i'm just wondering if i would encounter any trouble down the line from doing this on a tC, synchro grinding, rough shifts etc. (i really doubt it though, because synthetics seem to work great)

i made a trip out to summit and picked up 3 bottles of fluid and a long funnel. then went to sears and picked up a 24mm and 27 mm socket...too bad they were 12pt, but they were 1/2" drive and half price clearance! woohoo!

 

^^^^ bump to answer my question, thanks!

 

shouldn't be any problems... it's just replacing oil... it's just better oil

it won't cause any more problems if the stock fluid was in it.
for the most part.. it makes the sychros happier.

 

i just did this. it took me about an hour, because i was dickin' around the whole time and trying to be careful, talking on cell phone etc.

a few pointers i'd like to add:
-make sure you have a 24mm and 27 mm socket. 6pt sockets are prefered, but all i could find was 12pt at 1/2" drive. don't buy the sockets that are like 3 inches long, you wont be able to access the drain plug. also, you should probably have an extension of at least 6" to get to the bracket bolt that holds the reverse sensor wiring, but it isn't totally neccessary.

-remove your airbox, it's so much easier, and while your at it, check your air filter and replace if totally dirty

-i didn't use ramps and i dont have access to a lift. instead i jacked up the left side of the car and used a jack stand. then i removed the front drivers side wheel to access the bolts on the tranny.

- the reverse sensor uses 27mm socket, it's in there pretty snug, but becomes loose quickly, so watch it when you crank on the bolt, so you don't rip up a wire or something.

- the drain plug is right up against the frame, i couldn't get a good amount of leverage, so i tapped it a couple of times with a hammer and it came loose. this is wear a shorter socket is key, because you will not be able to fit a socket that is bigger than 2" in there.

- the fill plug with the sticker on it is easy and is pretty much the same hardware as the drain plug

-like many people said, keep the reverse sensor in when draining. i kept in the fill plug also. it glugged out fluid for about a minute before quitting. of course i saved my fluid in case i have any trouble in the future and have to bring it into the stealership. after draining, snug up the drain plug, of course don't overtighten.

- make sure you add fluid when the car is level, so you can see when you have the correct amount, by it flowing out of the fill plug. snug up the fill plug and the reverse sensor, but don't crank them on super tight. you need to add 2.5 quarts


at first i wasn't totally impressed. everything seemed like normal...then i noticed that all my shifts were quieter. i had been getting a light crunch sometimes when i shift 1st to 2nd, like a lot of people do, now i don't get that anymore.

the biggest improvement is downshifting. i'm pretty good at rev matching, but in the tC, 2 out of 3 times it would still result in a bump/sway. now it's much smoother and i can do most downshifts without much motion transfer at all. it also seems to help out a little when i use my a/c, because my shifts were horrible when the a/c is on, now they are a little smoother.

up shifts also have improved and gotten rid of the bump/sway.

i picked up my redline mt-90 tranny fluid from the summit store. it's not that far from my college, so it was no big deal. 3 bottles came to $23.85 + tax. i really think this is an awesome change compared to stock. combined with all my other shift mods, it really makes driving much easier and enjoyable.

and one more thing. i had grinded 2nd gear maybe 3 times, i grinded 3rd gear once, i grinded 4th gear once, i grinded 5th gear once, and i grinded reverse twice...i learned on this car, what can i say! although all the grinds were within the first 2 months of ownership. some people said that they're tranny oil was gold colored when they drained it. we know that it's actually bronze that they are seeing.
mine was honey brown colored and had no bronze flakes or coloration at all...i don't understand

 

just picked mine up, came out to $28 something with tax at my local Redline Automotive store.

 

how did your 12pt socket work? I already have a 12pt 24mm socket, and was wondering if it would be better if i picked up a 6pt for this.

 

No, if the 12 point fits on it, use that. More grip. Mine was a bit of a pain to get off so I'm glad I used a 12 point b/c even then it rubbed a corner a little round.

 

jus did this mod yest when i went to track and i love it, shifting does feel smoother and less notchy

 

i know this question has been asked but i wasn't sure whether it was answered or not. after how many miles should you change your tranny fluid?
