Subaru WRX STI Transmission & Front Differential Flush | Step by Step

[@asbestocide]

You're the 1st person that I've run across that actually shows exactly where the front jacking point is 👍

[@STi_Alan]

👍I thought showing the front jacking point might be helpful to someone since I had a hard time finding many sources on it

Thank you for doing this video. I just had my 30 K mile service done last month @Irvine Subaru here in Ca. A weird thing happened though, after the service when it shifted in 4th gear it scraped. I took it back and a week later it migrated down to 3rd gear when I shifted it scraped. My 2020 STI was in the shop all of May. I got the car back in the beginning of June. The head mechanic @irvine Subaru went over my car with a fine tooth comb. It's shifting and running better than ever. They replaced the 3rd and 4th gear synchros in the transmission. Maybe they had someone the first inexperienced working on it the first time. A learning experience for me. I know my car. A great video brother. Subies forever. I'm @44K miles. I will change my clutch @70k. Take care and keep up the great videos. You are very lucky to be able to work on your car. 😊

Ouch!! Thanks for sharing your story! That’s the worst feeling getting your car worked on at a professional shop and them not following the proper steps or ending up with damage to your car, especially something as valuable as the STI 😢 I still have to go to the pros for the things I can’t do but experiences like these are one of the reasons that encourage me to try to do things I’m able to myself. Thanks for continuing to tune in! There will be more to come ✌️

@@STi_Alan No problem brother. I am a retired Aviation Electrician from the Navy and I am now a Facilities technician and mechanical technician. I can do the maintenance on my Bluebaru but I just don't have the time and a place to do it. It's great to watch you KZbinrs do the work. It helps me to appreciate our beautiful platform.

I bought my 2020 STI from Irvine Subaru. They did the same service for me at about 33k but it didn’t get that issue luckily. However, I did just get my cat replaced at 54k due to intake leak issues… fortunately that was covered.

[@STi_Alan]

@@TheU2bstud 😮 glad they covered the intake leak and hopefully it didn’t take to long for them to fix it!

[@deecee7820]

4th gear grind is a very common issue after replacing the fluid

[@xrmerkur]

your channel is doing great things. i’m gonna stay tuned in.

[@STi_Alan]

Thanks!! Look forward to more!

[@mamaman59]

Thank you for the video, it is really helpful. However, based on 202 STI service manual, both filelr plug and drain plug of the 10mm Hex type should be torqued to 36.9 ft-lb. The T70 TORX drain plug should be torqued to 51.6 ft-lb. BTW, the front jack point is spot on.

[@STi_Alan]

Thanks for the information! I got my torque specs from others who've also done the transmission flush but you definitely can't go wrong with the official service manual specs

[@jamesvang4392]

Great step by step.

Thank you!

Hey Alan, thanks for the videos! subscribed and excited to see your adventures!

[@STi_Alan]

No problem! And thank YOU for watching!! I’m glad you’ll be coming along for the ride ✌️

[@420shayaa]

Clear. Solid info thank you!

[@STi_Alan]

no problem! I'm glad I could help✌️

[@jamesyang233]

Awesome video!!! Keep them coming

[@STi_Alan]

Thanks!!! Look forward to more!

@@STi_Alan next....clutch fluid and brake fluid...it's due!!!

[@petrmiskerik]

Thx for great content and help to community....BUT. Your car is not leveled properly. So chance fill your transmission up properly is quite small.

[@miriamvivo4279]

Great jack stands. I have same

[@STi_Alan]

Great choice! They're definitely worth the price!

[@10thFTW]

Just picked up 6 qts subaru gear oil and 2 gal subaru coolant for my AOS/4th mod n paid 178$ 😢 #STILife!

[@STi_Alan]

😅 The cost of owning an STI sure is expensive but the joy it gives is priceless!

[@robertneak8613]

So both diff and tran use the same place where you put fluid in

[@STi_Alan]

Yep that’s correct! The fluid you put in that one fill hole goes to both the front diff and trans

[@robertneak8613]

@@STi_Alan thanks I keep that in mind very interesting .

[@stickyrice7610]

Where did you buy all your parts

[@STi_Alan]

All sorts of places such as Amazon, Harbor Freight, Walmart, etc. Wherever I can find the best deal

[@lasycs]

I thought you would need to have the car level (on 4 jack stands) to change the diff and trans oil? Don’t you think?

[@deecee7820]

car should be leveled

[@miriamvivo4279]

All good

[@dougl4253]

Those are different numbers then mine

[@ParalyzedNight]

Car needs to be level to drain and fill trans, front diff and rear diff. Either get it on 4 level jack stands or do it on a hoist. Doing it the way this guy did in the video is incorrect and may cause damage down the line because not all the old fluid gets drained and being at that angle doesn't get filled up to the correct level.

[@supreme2544]

Not an accurate fill and drain when the car is angled on jack stands.
