Depends on the working conditions.
In a semi-heated shop or small garage with lights, and flat level floor,
some jack stands and a floor jack, it's not that bad.
Taking out the engine and trans as a unit is quite easy.
( but if doing just the trans, then just take that off and leave the engine
in place - you need at least a bottle jack also )
On the other hand, if it's 'all outdoors', or worse, outdoors and not even
on flat level pavement, then yes, that's a real tough thing all right !
For some odd reason I always liked to drink a lot of coffee and do it in the
middle of the night ! no distractions then.
Sounds to me that given the time of the year, and I gather not excellent
working conditions, and the engine is working all right, like has half
decent compression and no coolant leaks, then just to the trans for now.

I did not mention, my 84 Vanagon broke its transmission last week.
I heard a loud snap from the rear, like breaking an axle and I lost
power to move forward. It was in first gear trying to move into another
street on a right turn. I can still shift back and forth to every gear
including reverse. But As soon as I try to let go the clutch pedal I
can hear noise from the transmission. So the transmission is toast.
I have one used cheap spare that I can replace. But once the engine
and the transmission is dropped I have a decision to make between a
real quality rebuild or a cheap one by myself. I do not need to do
anything with the engine if I want to go the cheap route. If I want
a quality one then it's a lot of money and the engine should take
the opportunity to be done as well.
It's not fun to do something like this in winter time.
