Couple things the bushing is worn, along with the main shaft..which if worn pass spec. well allow second gear to rock back and forth, which in turn push the sincro ring to move forward and thus out of gear. End play of the main shaft is another place to look at..along with the sincro dogs and retainer spring. Also the the area where the input and main shaft marry up..If the mating areas are worn pass spec. then all the new bearings in the world won't fix it. I have found that the wear of the bushing and the main shaft, incorrect end play of the main shaft are the main areas to look at...Hope this helps

I replaced 2nd gear and synchronizer assembly and it still popped out! Ended up needing a stronger poppet ball spring in the shifter assembly. The info. on worn mainshaft and end float is also correct. !! John

Is this the T-84 or T-90 transmission? This is a common problem on T-84's.
