[AT] Ford NAA with aux tranny??

[John Wilkens]

Dudley, what was the use of the Howard heavy duty "straight through 
gear set" you mention?     The other issue...I need to determine more 
about the aux. trans. that is in this NAA.  I wonder if it is just a 
Howard with the shifter coming out the other side (Left) of the 
case.  I do hope it is not the light duty Howard rototiller 
gearing!  It definitely gives the NAA a slower range in all gears but 
when it was running I didn't notice if it changed the rpm of the pto 
shaft.      John
