DIY - changing your transmission fluid/oil, M/T 7afe Options

[Bitter]

i'd like to state one think. oils should ALWAYS be drained hot after a hard romp so that sediments are stirred up and drain with the oil.

also replace the standard plug with a magnetic tipped on to trap steel shavings.

sorry for bring in this thread back to life..but...

idk why but i cant find both the fill/drain bolt in my auto 5sfe...am i not lookin hard enough...or is there anotehr location for it???...

you're welcome, and yes, the manual transmission is much easier to change than the auto, i just changed mine, and it feels a lil better but it still grinds, oddly enough i only put in about 2 1/2 quarts before it started to drain itself out again, so i just left it at 2 1/2 quarts, get a manual trans ftwwwwwwwwwwwwwwwwwwwwwwwwwwwww

I have tried a few fluids.



ATF works best from my experiance. But I will give syncromesh a try to stop my grindage.

nice tutorial!

thanks.

Syncromesh is the way to go

There are 2 reasons to have fluid come out of the fill hole when you remove the plug.
One is

Make sure you fill the tranny with all four tires on the ground. If the car is jacked up when you're filling it, there will be too much fluid in there.

So when somone opens the filler hole tranny fluid will come pouring out of the hole.

DEF

Also, if your flat spot is on a slope....



The other is if the trans is hot at all, the fluid expands, and raises the level.
So if you have driven it 30 min ago, it will probably still be hot.

Cant get the damn fill hole off. Its chewed up a bit now and its just being a pain.

[Steevo]

Using a cold chisel make a indent in the side of the plug square to the plug itself, close to a corner, then point the chisel at the next corner and give it a whack.

It might be because you are putting ATF(Automatic Transmission Fluid) into a standard transmission.

And btw, it's called "gear oil" or "ATF" depending on the type of transmission. Let's all get the terminology correct.

Gear oil goes into standard transmissions.
ATF goes into automatic transmissions.

We might wanna add that to the information, so that people aren't using the wrong terms, and buying the wrong thing.

If someone doesn't know what they are doing, and they go into AutoZone to get something to fill their transmission with, and they are looking for "transmission fluid/oil," they will probably end up with ATF, much like Steevo here.

alot of manual transmissons use ATF as well. i know that in cold climates its often used instead of gear oil and infact many manual transmissions require it outright no matter what climate you're in.


you guys might also try the scott grey mix which is "Mix 2 parts Redline MTL and 1 parts Redline MT-90". that mix has been known to help smooth shifts and help with grinding.

I'm about 99% that the Celica's specs call for gear oil in manual transmissions. I go by that.

i bet they do, but you man a unilateral statement than all manual transmissions take gear oil. thats not correct.

I never said "all".

See below:

*Implied/Understood words are red and bold, as they pertain to this message board. This isn't an all inclusive board. So I speak in reference to Celicas.

As a fact the shear stability of the ATF in use was more than adequate for use on the lubrication standpoint, and the addative package contains almost the same amounts of sulphated ash and zinc.

Really and honestly it helped alot while it was in use. It went from a 3K shift with grindage, to a 4+ shift.


I changed to the syncromesh last night, and no more grindage at all!! mad props to whoever was pouring out the money to try and fix this problem. I found it at the local Autozone for $6.59 a quart, and it was well worth the cost.

Just a side note about it, it is alot thinner (lighter in oil weight) than the 75W90 that is reccomended for use in the transmission, but it works GREAT!!

[tonytutino]

man this pissed me off so much, i found the first bolt, the fill one. but i have no idea where the drain one is, i mean i just couldnt find it... does anyone have anymore pictures that show 'where' it is like he showed 'where' the first one is by circling it or something? cause i spent 30 bucks on that syncromesh and i wanna use ittttttt
lol thanks alot if anyone can help

[97lestyousay]

It sure is nice to get a list of tools needed for jobs
without going thru a book to do it. I have used these
stickys and how tos countless times. They are always
a great reference.

[Batman722]

Randy, did you change the fluid on the Celica or the Corolla ?

Clearly since this is not an "allinclusive" forum it was
the celica.


OK you caught me, I am using this forum for info on
my other toys as well. I am changing it in the rolla. It is
a little tighter though. I'm just using some 75-90 because
I am replacing this tranny soon and I couldn't find sycromesh
anywhere around here . To bad GT4s don't have hubs
I need to rebuild one on my truck.

While we're on the topic, What is the differences between normal engine oil and transmission oil? I couldn't imagine too much difference, they do pretty much the same thing? I'll do mine again soon with syncromesh cause i have to do my inner cv's and i may as well change it. Cheers fella's.

transmission fluid (oil) is very thin, much thinner than normal engine oil. A transmission has many more smaller moving parts (gears) and the oil needs to flow throughout easier.

Sorry but I thought we should clear this up. To start I am a lubrication engineer so I have a little working knowledge and experience on this subject LOL.
I'm sure Dustin just got his wires crossed when he typed this as having changed it he probably knows by feel.

10w30 engine oil is waaay thinner than 75w90 Manual Transmission Oil. Gear oil is thicker because it is not having to be pumped through the small oil passageways of the engine block. This is also why it does not have to be changed out as often as it will take alot longer for the viscosity to break down to the point where t is no longer lubricating.
