how do i lock uni drive transaxle

[stevasaurus 23,274]

It is a matter of where that bull gear meets that 11 toothed part of the mushroom gear...the teeth are the same...it is the height of the differential (different axle lengths and how the carrier sets)) and if it is the right height for the 2 gears to mesh right.  I am thinking if the gears mesh right...it will be OK..  Does that make since??    I may have some pictures, but not of this transmission, but I could show you what I am talking about.  Let me know.
