Built manual transmission or where to get sychros
 
Well since I'm not the only one having issues with terrible synchros do we have any info on rebuilding this transmission? or just replacing the synchros?

There's a 5 year/60K miles warranty on the drivetrain. Are you out of warranty?

No but I have a competition stage 3 clutch, short shifter, aftermarket bushing, and the mtec spring.

IMO switch to stock then go to the dealer.

Wouldn't they give me an issue with having a supercharger? The stock clutch slips so I had to upgrade the clutch.

Nope, perfectly ok /sarcasm.

I don't know of any shops that are rebuilding these AISIN gearboxes. The dealer told me that they don't fix them; they pull and replace the complete unit.

It's a pity, really. I like the short throws of the gearbox but that second gear synchronizer "scrunch" greatly lowers my opinion of this gearbox, and the car, for that matter.

And even if we can live with this problem, what will prospective buyers think when trying to sell the car when the time comes? I can just imagine the excuses when the buyer goes for a test drive and experiences the scrunch: it's normal; they all do that; your not holding your tongue just right; or... .

The reason Subaru dealers aren't rebuilding these things under warranty is Toyota/Aisin has a unit replacement policy, and the dealerships "don't have the special tools required for disassembly or reassembly." I put that in quotes because there are plenty of generic tools that can be used, and the service manual has the complete procedures for overhauling these units. The dealership can order internal parts.

So, if you have a trusted mechanic, it can be done.

Yes you can rebuild them I know I have one apart on my bench. You wouldn't want to though because the cost of the parts which have to be dealer ordered are outrageous. For 4th gear, synchro springs and pins, the shift collar and a bearing was over $600!!!

Jesus. A whole new unit lists for about $2300.

Dipstik-sportech 06-10-2014 12:54 PM

U can find it for less that 2000$ if u search. It's a junk trans that's why its cheap

True, the trans in this car seems pretty low end, especially if you do any type of FI to the car. I have a friend pushing over 400whp and is on his 4th transmission. Though he does have a pretty hefty clutch and clutch pressure plate for track racing.

I'm doing a little over 400whp myself (FBM FI kit) and shifting at high RPMs seems pretty difficult since the gears don't want to shift quikcly under full load (possibly from all the torque and inertia due to Forced Induction FI). I hoping my transmission doesn't take a crap on me too lol.
