I was installing the Gearset (non-RA) that i bought a few weeks ago. Into my 02 USDM WRX.
The shop puted it all together and installed it into my gearbox. we
installed the shift fork for 3 gear that was provided with gearset also.
(was it nessesary?) and when i took it for a drive to test - the 3rd gear
wouldnt work. it will pop-out when i put it in and reliece the clutch. Also
when i put it in i can feel that is is just not going deep enough. (compare
to 1st and 5th also) It justl looks like the 3rd gear is not pushing in all
the way in. The shop that installed the gearset in told me that all the
gears and shaft is the same design just different gear ratio BUT the 3rd
gear. the gear is different. the tooth not the same as on the stock 3rd
gear. all other gears looks just the same except for a number of thooth but
3rd gear is just different from stock. So is there anything specila that we
need to do when installing this 3rd gear? maybe we had to keep the stock
fork and not install the one you included? because the stock fork and the
one that was included is almost the same. the only difference in the fork is
a small difference in possition of a hole in the middle of the fork.

Did anyone had same problem installing the gearset and how did you solve it.
Thanks for the help.
