" I forgot about that Andrew! But there is a slight problem. The M35/37
" air cooled trans was only used behind 199 and smaller sixes in big
" cars, 232 in the light weight postal Jeeps and early Hornet/Gremlin.
" They weren't used behind the V-8 at all. The air cooled bell is very
" different from the radiator cooled models.

yes; it's obvious the bell and converter are very different between
air and radiator cooled models, but i'm working on the assumption that
front pumps are the same.  that would be amc's way...

" I'm not sure about depth of the bell either, though I suspect M4x 
" trannys all used the same bell whether behind a six or 290/304.

sixes had the small bell pattern all through the warner auto years...
but the front pump would make sense.

i vaguely remember seeing 232 and 290-2v torque converters listed
together in the mitchell master interchange, indicating they were
identical externally at least, and maybe internally too.  yes the v8
has more torque, but at a much higher rpm peak - 2800 vs. 1600 for the
232 - so perhaps one spec would fit both apps.

" I think the M37 was a heavier air cooled model, but it might be
" radiator cooled (M35 modified for radiator cooling?). 

my '66 01 tsm has m35 - 199, m37 - 232.  my '68 tsm shows m36 - 199,
but nowhere do they mention air or water cooling, not even for the
290-2v - m40.  otoh they do say a trans cooler in the radiator is std
with v8s and optional with sixes...

" There may be bosses that can be drilled out for converting the M35 to
" radiator cooling. I know there are external pressure test points. I'd
" thought about using one of those then drilling a hole in the edge of
" the case just above the pan lip for a return. I never did as I was
" afraid it would reduce pressure to much.

hmmm...  i wouldn't want to try this myself, without first having both
types of tranny case side by side to compare similarities.  i would
want to route the fluid cooler the same way as in normally fluid
cooled trannies.
