I changed the transmission fluid/oil in my 7afe recently and Manny (presure2) took some pics - thanks Manny wink.gif
I was having some slight grinding going into 2nd gear in higher RPMs and I figured changing the tranny fluid would be a great idea. Since it has been changed, no more grinding biggrin.gif

tools needed : ratchet, 24mm socket, 3-4qts transmission fluid/oil, oil drain pan, jack/stands
time : 30min - 1hr, depending on your mechanical skill level

DO NOT attempt this when engine is hot, wait until the engine is very cool/cold.


first you need to loosen this bolt (fill plug) with a ratchet and the 24mm socket

bolt removed

it is located here, it is facing the front of the car. The transmission is circled in yellow and the arrow is pointing to the bolt location

the bolts are usually very tight and could be difficult to loosen

next, jack up the front of the car (putting it on jack stands is always safer) and with the 24mm socket you need to loosen this bolt (drain plug)

Remove drain plug. The drain plug is located directly under the transmission. You may need to remove some of the plastic under the engine for easier access. Be sure to put the oil drain pan under the bolt when removing because the old fluid/oil will be pouring out.

now after the old oil has drained out (10 min later), replace the drain plug - make sure it is secure - and lower the car.

My personal choice
Pennzoil Synchromesh

pour 3-4qrts of the Synchromesh into the fill plug hole (you might want to use a long funnel or pour/squeeze from the bottle into the hole) until full - it will start pouring back out. I used just less than 3qrts

Once full, replace fill plug - make sure it is secure - and wipe up the excess that has spilt.

Done.

Notes :
- be sure to dispose of old fluid/oil properly
- according to the BGB - 7a transmission refill = 3.5qrts, 5s transmission refill = 2.6qrts
- this procedure should be the same/similar for both 7afe and 5sfe

Awesome work guy, I added to the sticky.

Now go tear up those streets.

Awesome job you guys. I've still been too lazy to change mine, but I think this how-to might just motivate me to get a move on and finally do it. wink.gif

To make refilling the transmission eaiser, go to a marine store and buy a pump that is used to put gear oil into an outdrive. Just remove the fitting that comes on the end of the hose, insert the pump into the bottle and then pump the gear oil into the transmission with very little mess.
TTE
Its best oil for manual transmission. I tried it on my other car and it totaly cured the problem.

so on the 5sfe, the fill hole is pointed slightly downwards on the front of the case? i think i'm doin this right but i don't think fluid should have come out of the fill hole when i opened it up?
Supersprynt
Did you drain it first? If you open the fill hole while fluid is still in there some will come out.

ok i was just making sure i wasnt doing something wrong (this is my first time doing tranny fluid) i was always told that the fill hole wouldnt have anything come out of it, i'll have to tell my friend he's an idiot now lol
Defgeph
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.

yeah, i think that's what happend the last time it was filled. it's draining right now, i'll drop it down and finish the job up. thanks guys, i love this community

What I usually do is get a funnel with a tube.
Phat_99CeliGT
i gotta do mine soon.
i use Redline though. i use it in all my probes and its great.
$7-8 a quart though.
blu94gt
I just used Coastal gear oil, it was all they had in stock still and I just needed to get it done. Instead of a funnel, they sold a hose that screws on to the bottle, you twist the base of the hose closed, get the hose in the fill hole and then turn the bottle upside down and fill the tranny, the whole job was really fast.

synchromesh owns all. ive been recomending it to everyone
Starcraftjunkie
I'm thinking about changing to synchromesh as well, but I got a question.
So if you do a summary of the steps:

-jack up car
-remove fill bolt
-put drain pan underneath drain hole
-remove drain bolt and let fluid drain out
-screw in drain bolt
-drop car back down
** here's my question **
-put in new tranny fluid
-screw in fill bolt

But if the car isn't jacked up, isn't it very difficult to get to the fill hole? It appears to be mostly accessible when you got the car jacked up. Or is it accessible from the hood area so you just have to reach in?
trdevelopment
im gettin ready to do this also im going to use lucas is anyone using it?
lagos
your going to need a funnel with a long hose to do it with the wheels on the ground. i just did mine while it was jacked up, it overfills it a little, but i havent noticed any negative side effects from it.
Cutrara
I just did mine, and WOW! What a difference, everything is so smooth. I couldn't find my jack, so I just drove up on a 2x4 under each wheel and had enough room.

I didn't need a funnel to fill it up. I dropped the bottle bottom first next to the transmission, took off the cap, put the top in the fill hole, and tilted it up. Sounds complicated, but it's easy and no mess wink.gif

Thanks for the How-to Dustin.
Batman722
glad things worked out for you Alex smile.gif

there is a lot of room to pour strait from the bottle for an ST, the GT is much tighter for space and a funnell would be easiest.

overall, changing it is pretty easy and well worth it.

damnit, seems to be much harder to change on the 3s-ge, it's really dark outside and i can't locate fill bolt.
Well i'll take a look tomorrow and hope it's not too hard to do, the tranny could really use a fluid change...

the 3sge tranny is very similar to the 5s and 7a (drian/fill bolt locations)
you can do it wink.gif

nah i won't have any problems to actually do it, it's just that i'm so lazy....

Nice wright up, seems to have been a big topic lately.

I tried to do it but I couldn't get that fill bolt off. I even bought a 24mm socket for my ratchet and tried to make a break bar so it would loosen, but I just couldn't get it off. frown.gif What a waste of time...
Cutrara
Try putting some WD-40 on there and letting it soak in overnight.

don't give up guy, it is well worth it when it is done

hmmm... okay then, i will try it again next week after finals. I think I'll do that WD-40 overnight thing and hope for the best...

use a long braker bar, and make sure you are using a 6point socket (no 12points!) those bolts are made of really soft aluminum, and can be striped very easy. i know, i almost totally striped one of mine.
Dunners
I changed mine yesterday with some semi synthetic trans oil and i didn't notice too much of a change if any at all. I wasn't really expecting fantastic results but it still grinds a bit when changing. I didn't use syncromesh. I think i put a bit too much in, any negative effects of that. I know what you're talking about with the tight bolts...had to use a massive breaker bar. Thanks for the great how to.
Batman722
I had first changed mine and used Mobil1 synthetic and it still grinded. I took the advise of a few others and then changed it to the syncromesh, no grinding at all since.
zipstrips
redline MTL or HD shockproof is the best tranny fluid i've ever used.
Dunners
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.

makes plans to do this next weekend smile.gif

it'll be alot easier with a hoist, but hey you get that sometimes...

nice write up
Jeremy1210
man, I never saw this before for some reason... I think I def need to do mine. I have driven like 115k miles and never changed it...prolly waaaayyyyy past due for a change

How often should it be changed?

technically manual transmissions are designed not to need a lube change for like 100k at a time, but I think the Toyota manual says every 30k to change it.

And guys...it's TOTALLY EASY to do, the longest part is just pouring the fluid in.
Cutrara
30k? I used a cheap brand about 5k miles ago, I think at 10k I'm going to use Syncromesh. Every once in a while I get a little bit of grinding going into reverse.
eggman40
I pour my fluid in from the top of the tranny while leaving the filler hole open so i know when theres enough in the tranny. Is this bad? i have all four wheeles on the floor when i do it, and so far my tranny works fine. It was pretty hard to fit a bottle where the filler is so i took off the big bolt on the top of the tranny (where the gear selector is) and poured it in there.
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???...

EDIT:..some1 plz slap me.....hahha..jus noticed it was for a mt .....gosh...no wonder i cant find it.....i found out that it needs a 10mm hex socket and a filter n gasket kit.......
pure_dx
*slaps* dew_hoe_gt

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.

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

QUOTE(defgeph @ Nov 5, 2005 - 1:20 PM) [snapback]353477[/snapback]

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.
StaticKnotX
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.
