" The efficiency of an automatic transmission is pretty good;
" somewhere in the upper 90's percentage-wise.

what about those figures we've heard about 25hp to spin a tf904 and
40hp for a 727?  manual trannies are 98-99%.

" Horsepower NOT sent to the wheels becomes heat.

true.  where else could it go!

" It's about 770 watts per horsepower if I recall. Here's chart
" showing how much heat is produced:

close enough for your estimates, but exactly
746w sae
736w metric

the sae number is a conversion from something like 33000
ft-lbs/minute.  the metric is similar, rounded to metric units [4500
kg-m/min?]
