Hi Guys,

So after many months of struggling to figure out why my, rebuilt by a local high end classic car restoration shop, transmission would not stay in 2nd gear (Thanks so much to Bruce Madden for helping me to figure it out) it comes down to a 16nth of an inch. My "high end" restoration shop installed the replacement bearing https://www.123bearing.com/bearing-housing/other-bearings/402082-skf.

Turns out, that bearing is off by a 16nth of an inch where the circlip sits and THAT IS enough to allow the shaft to drift back and forth during shifting and and cause it to jump out of 2nd gear.

I pulled the transmission Back out of my car, In my garage, took it Completely appart, Finally learned how a syncro transmission works and With the help of Bruce Madden, figured out what the problem was and then put it All back together with an Original rear bearing that Bruce had. Now it shifts beautifully and holds in all gears.

Wow! What a learning experience :)(
