In this episode, Aaron and his brothers start the rebuild process on the WRX 5MT they picked up. They tear it down and go over how specific components work while also discussing what parts need replacing and how to go about it!
This was the first time any of them had opened up a Subaru gearbox and they figure things out as they go without looking at any diagrams.

Since we shot this, I’ve picked up another trans with a blown 3rd gear that I can use for parts, and my uncle has a big shop press that I can use to pull gears and bearings off the shafts and reinstall everything! I don’t plan on using this transmission in the near future, so It’ll probably be until october or so before I actually get around to rebuilding it.
I hope you enjoyed this episode, I sure had a fun time tearing into it. Transmissions are about the only thing i haven’t dealt with. Its usually simpler to just find a replacement trans and swap it in. I’ve always been intimidated by transmissions just because they have so many moving parts and everyone says you need specialty tools to work on them. Its really liberating to finally get over that fear and realize its just another component!

I appreciate the video, fellas! Did a 6mt swap on the Outback, and needed a little encouragement on the teardown of the old 5mt. This will become a rear wheel drive trans for later projects!

I got subaru legacy 99 2.5 A/T I'm not sure what's wrong with it the I disconnected the rear axles and the front axles are jamed and no reverse nor drive, my question is would it be the transmission or the Center differential and I noticed the front tries or larger than the back tries

It's my DD; I've found plenty of low mileage JDM Legacy turbo transmissions and some WRX ones but I can't decide whether I want to buy one of those (since I'd have to swap my rear diff as well to match the final drive) or just rebuild my current one.

3:25 - "This" is not sending power to the front diff. These gearshafts in the rear housing are the two output shafts to the rear, coming from the center diff. It's just not in a straight line, since the crankshaft is supposed to sit a little higher for ground clearance and stuff.. but you figured it instantly, sorry;)

How difficult is it to remove the transmission? Does the engine have to be removed too, or can it stay in the car?

@Dirtcheapdaily 7 жыл бұрын

+jds7777's creations its relatively simple to remove the transmission in a Subaru. You can leave the engine alone. There's 5 bolts that hold the transmission to the engine. One on each corner, and a 5th under the starter. Then it's just removing the axles, driveline, exhaust, and shift linkage. Check out my manual swap series for more specifics! The next episode will be out tomorrow 👍🏻

Watching the guy with red shirt try and figure out how the center diff, gearset and front wheel output interacted was painfull. Its cool you guys are pulling it apart to see how things work. But if you have no clue, its best not to dribble non-sense while you figure it out.

@BoxerTechGarage 7 жыл бұрын

I have studied the FSM and teardown manual for this transmission very extensively for this transmission as I'm getting ready to document this exact tear down for my own video series, and I was literally yelling at the guy in the red, correcting him on what exactly it does. The gear set outputs to the center diff and those gears he was saying was the center diff are the transfer drive gears. They really should have the FSM while they're doing this. You can't guess when it comes to transmissions.
