02 Tacoma gear oil

Hi everyone. I have a 2002 Tacoma 2.7 4 cyl 5 speed. It has 150,000 miles and the gear oil in the transmission has never been changed. 1. I didn't know if it needed it yet or not. And 2. If so, how do you do it? I've seen a couple videos, but they were all for automatic transmissions. Any help would be appreciated, thanks.

 

Be careful as most of those torque specs on drain plugs are dry not wet. You can over torque them easily i prefer to just snug then.

 

Very easy to do. Instructions are in the first comment.

 

I used Redline MT90 when I did mine. Gear shifts are smoother and it was a really easy oil change. Do it and you won't regret it. Very easy.

 

Do you recommend the mt-90 in front and rear differentials as well?

 

I don't think you can use it in the diffs. Could be wrong.

I had the same question.

 

Thanks for all the help yall. I've never had any problems out of my truck and just wanted to keep the maintenance up. Should be an easy thing to do.

Mobil 1 75w-90. I like to use the top of the line synthetic so I only have to do it every 90k miles. I've gotten lazy in my old age(mid 30's lol).

 

Might as well do the diff's and transfer case while your under there.

I just did this and used new crush washers. What I didn't know was that they are different.

75w-90 in the diffs and transfer case? Also wheres the drain/fill plugs on them?

 

Nice on the OEM part numbers. Maybe we can get a mod to do a sticky with an OEM parts number list?

 

No you do not have to use synthetic.

75w90 gl-5 in the diff's

See your manual about how often to change and fill amounts.

Search YouTube for videos for locations of fill and drain plugs.

 

Link to good video. Hope it works.

 

Ok, thanks again. I'll do like you said and look on YouTube so I can watch it be done.

 

Nope, you sure don't have to use synthetic. Not sure on the frequency of drain and fill that Toyota states. Probably 60k? I'm sure someone has an owners manual here, it's prolly online as well. When doing the diffs and transfer case, pull the fill plugs first, just because sometimes folks can't get that one out but they can get the drain plug out. Then they're stuck with an empty diff with no way to fill it.
