[TR] high engine rpm

Could be the tach is wrong.  Should be closer to 2900 rpm (with 205/70-15
tires & 3.7 gears), and reading 600 rpm high isn't terribly uncommon for
these old mechanical tachs.

Lots of ways.  If you jack up one rear wheel (leaving the other touching the
ground or otherwise blocked from turning), you can put a mark on the wheel
and on the driveshaft and count how many turns the driveshaft makes for 2
full turns of the wheel.  The driveshaft will turn less than 4 full turns if
you have the standard 3.7 gears; more than 4 full turns if you have 4.1 or
4.55 gears.

To get a more accurate value, turn the wheel 20 full turns, giving 37 turns
of the driveshaft for a 3.7, or 41 or 45.5 for the other ratios.
