What type of tranny? If your using a muncie 4spd and using 3&4 gear only you will need to remove 1&2 gear.Something about not getting enough oil to 1&2 on the main shaft. That is what i was told.

Yes but that is not legal. Must have have working gears.

used both and both did same thing ya welded second gear to shaft has to be some machine work that can increase oil to that area

I used to run a Saginaw(sp) three speed with all its gears intact. I never had an issue with reliability, and with first gear still usable, moving in and out of the pits was much easier on the clutch. My only concern was blowing second gear out of it, so I didn't throttle up till it was in 3rd. My next mod will be the same.

We have already welded first gear twice... what's the trick?.

What are you running for oil? I have read that if your oil is too thin it may do that.

I believe gear oil but would have to double check

I second that! Been running one in my super since I started, same one to be exact! Had a rebuild after it kept popping out of gear one night and been perfect since. I run regular old dino 85-140 and change about every 8-10.
