2002 WRX Transmission and Differential fluid change

Today we change the manual trans and diff fluid on an older 2002 bugeye WRX with 230k miles! the fluid was quite dirty and had a lot of brass syncro material. Maybe we'll be replacing the syncros in the future.
Thanks to www.bensound.com/ for the music

Very nice detailed procedure, encouraged me to do it myself lol. Question, how many quarts of gear oil and what type do you recommend and not so expensive? just want to change the gear oil.

[@4KMotoring]

The 2002+ 5speed transmission should be 3.8qts. 75w-90 is recommended

[@lalolalo1233]

@@4KMotoring yeah that's the one I have, turbo sedan. Perfect thanks! ama get the oem plug and washer as well to ensure no leaks for while lol.

[@mcsqueegee81]

What turbo, what injectors & fuel pump? I see the stock intercooler there. Did you do upgrades? Take it to dyno? These cars are so fun

[@gianc1753]

What fluid was used for transmission? (75W-90?) what about rear axle fluid?

[@jukeboxzero1]

Subaru manual calls for Three Bond on the plug threads.

I feel like I might have heard noises in my diff like a small Metic Ali noise ?

[@mcsqueegee81]

Did you stay with the stock brakes? Was one of the 1st things i noticed, that needed upgrading on this car. Ended up going with willwood kits for front & rear

[@mcsqueegee81]

If going to do sti, 6sp swap, then of course makes sense, get to use the brembos, from sti set up. Is another good route

Does my 2003 wrx have male or female axel inserts…? Truthfully I don’t know to tell the difference

[@fuzexninja1292]

What fluid did you use for your front and rear diff is it the same fluid?

Will this work for a gc8 Impreza

Where did you guys order the cv axles?

Whatever happened to the trans how has it been running since? Mine just started doing this within 500 mileage of this car too

[@4KMotoring]

Transmission held up fine until the head gaskets blew and the car transferred ownership lol

[@jacobbivens8302]

@@4KMotoring whew what a relief I bought mine with the heads done. Still losing oil even after an AOS must have failing rings I’m thinking

[@cooperjadczak378]

Same thing for an auto?

[@4KMotoring]

No definitely not the same. The Automatic would require ATF (Automatic transmission fluid) I would recommend the valvoline maxlife multi vehicle ATF. Its pretty good stuff and its fully synthetic. Automatic transmissions normally have a filter that should be changed when changing the fluid. The differential fluid would be the same though.

[@yamilmelendez2667]

Im a little late but this man trans is the same as 02 subaru impreza rs manual right?

[@4KMotoring]

I believe so!
