Re: towing a 1984 cj7 with a dana 300 Tcase
I met a guy in 1992 or so in Gunnison who was towing an Aspen station wagon
with a motor home. The Torqueflite transmission didn't have any provision
for flat towing, so the owner just started up the engine and let it idle the
whole time. He told me he got 48 mpg on the Aspen towing it this way.
Removing the rear drive shaft is also an option to consider if you want to
tow the vehicle a real long distance.

Drive is not an option in a manual transmission. The correct gear to use is
either R or 1. If the vehicle has an automatic, then P is the gear to
select.

Clearly you have no faith in reality. The gears are not going to change from
one that is selected to N then to another gear that was not selected.
One would not select N for towing because there is drag generated on the
transmission output shaft that comes from the tcase (that comes from the
spinning tires) and this drag can harm the synchronizers, and then the rest
of the transmission.

There is no reason for this logic at all. I think this started on the
fact that you park a stick in R or 1st. I would never tow this way
because if as I said before it did engaged for some reason it would
blown/destroyt the engine from overspeed in a heart beat at highways
speeds if it did not toast Tcase first. Simple physics here, not old
wives tales.

You can tell a lot from the types of slips people make. Like when Clinton
did that Oval Office thing or when GW said "won't get fooled again" you knew
that that was their normal behavior. I don't believe that SnoMan has ever
driven a manual shift vehicle.
