The Ford type 9 with the correct (or better alternative) fully synthetic
gear oil does the same thing - crunch up to second or is it crunch down to
2nd,or both.
I find that blipping the throttle (I modified a 1500 throttle pedal by
making it a lot shorter) removes the crunch.
The (very) expert gearbox builder, Brian Hill, did say if the box crunched
when cold to add a drop of ATF to the gear oil but blipping resolved the
problem so I've never tried this.

The first issue is the tendency of the 1st to 2nd shift crunch. This is
worse when the tranny is cold and goes away as it warms up.
I can avoid it when the tranny is cold by gently performing the shift,
which I do religously now.
Putting in the 75w made the situation a little better. I would also say
that over time this tendency to crunch appears to be on the
decline. Maybe as a result of the synchos breaking in? All other gears
shift wonderfully.
