Default My si transmission build\rehab (56k no way)

It all started when a friend called me up to go to a local swap meet. I went to the meet with $40 to limit what all I could buy, but that didnt stop me... Long story short, I came home with a EF Si transmission for $25, only catch was that the 1/2 shift fork was broken. It sat in my parents garage while I finished high school and my first 2 years of college, but the time has come to get it off the shelf and into my car. Pics:



Funny foreign roomate and transmission



Bearing retainer is not there



Carnage



Said broken shift fork

Other than the input shaft bearing and the broken shift fork, there isn't much to fix. My only concern at this point is that 4th and 5th are misaligned slightly. All the other gears match up great:





I'm pretty sure I have both washers on the bottom of the input shaft. What else would cause this? My plans after I resolve the broken issues are to clean everything in the parts washer and check and make sure everything is within tolerance.

it's actually normal, once the countershaft (with the retaining ring on top) is snapped in place with the other half of the transmission they will be in alignment. it slightly pulls the shaft and corresponding gears since it sits sideways not vertical. G/L with the build you should be able to replace the fork with 5 sp d-series from 88-95 as they have the same part numbers. (cast alum forks are prone to breaking being the d-series weaklink along that they are missing the tab that the b-series have)

Wouldn't that just make the problem worse? My mainshaft is the one that sits too low.

On the other hand, I'm pretty sure I havnt lost anything (because I havnt pulled anything off).

that would be the case if the countershaft was sitting lower than the mainshaft.

your input shaft bearing is probably not sitting correctly, as it's damaged.

I would focus on getting that replaced and then seeing where this leads you.
