I believe he's talking about removing the 2nd gear from the main shaft. On all 32-38 Ford 3 speed trannies, 2nd gear is locked onto the shaft by a hidden spring, plunger, and lock key. You must depress the plunger thru a small hole in 2nd gear while moving the key. It's a bit complicated to explain. I put all this with pics in our trans rebuild book, so you might want to get a copy of the book.
