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

[Batman722]

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

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. What a waste of time...

Try putting some WD-40 on there and letting it soak in overnight.

mine was really stubborn too, i finally got it though. I just used my breaker bar and a lot of strength lol

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

[eyohannie]

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.

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.

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.

redline MTL or HD shockproof is the best tranny fluid i've ever used.

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

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

nice write up

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.

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.
