Absolutely incredible timing. Wonderful video with some really detailed explanations. I'm rebuilding a 2015 STI gearbox now and this is exactly what I needed. Thanks.

Thanks for the video! I ran into an issue where second gear stopped spinning once I pressed on the 3/4 driven gear. I flipped the center of the 1/2 hub selector when I pressed it all together the first time. I took it all back apart and flipped the only piece that I wasn't 100% sure I had on there right and everything pressed together smoothly! I still couldn't tell you which way the center hub selector is supposed to go, so be careful when you pull it off or mark the top when you are taking it apart. Mine fell apart on me when I went to clean it, so I should have been more careful.

i wanna buy a blown 6 speed, to rebuild it, i love learning about these things

@otl I was wondering where did you guys get that wrench to take off and put on for the countershaft lock nut?

Brother, you are a Subaru mechanic god.. what do you think about IAG Carbon Synchros?

second gear on my manual swap SVX blew up, so I shall bookmark this video lol

What kind of sealant did you use for the tail housing? I’m looking for a quality product.

Will you make a video of the installation? Very cool video!

I’m curious, Did you try to do cryogenic treatment and another kind of treatment to make it stronger for racing?

Wrx Sti 2016... Gear 3 crunches and gear 4 sometimes locks up and can't get it out, it can come out sometimes... What is the problem do you think?

so curious, do you guys not replace all the bearings, needle, tapered and ball bearings when theres a failure? Seems like something that is overlooked unless you did and it wasnt shown. Do you measure bearing preload when you do replace these bearings also?

Where’s you guys located I need a transmission rebuild on my 2004 sti 3 rd gear is getting worn

My buddy has a 2004 dccd trans we swapped into his wrx. The car wont move in any gear. If the car is raised wheels off the ground the wheels will turn ever so slightly but on the ground it wont move under power. Any ideas what we should look for? We know the car it came out of was in some sort of accident so my buddy bought the whole drivetrain from the car

How much should an STI 6 speed tranny rebuild be? Mine is slightly grinding into 2nd and 4th suddenly. My shop wants 3500 for a "basic refresh" plus 600 for removal and install. And then any upgrades or replacements ontop of that.

What minimum ton press would you recommend?

Where can you buy the gears and synchro set

What year STI did this trans come off of?
