wow that one of the cleanest h41 i has seen
Is there any outside indentification that tells you it is a H41?
Put it in 1st, turn the input and count the output; hope for almost 5:1. An h42 is 3.5:1.
actually it's pretty obvious that the tranny is a H41.
Look at the 1st gear in photo #1. It almost reaches the top of the casting- thence a H41.
H42's first gear sit 3/4" or more below the top of the tranny casting.
ASSuming 4:11 diff...
It should work really well for him.
