Automatic or Manual. Which is the best?


If you have an automatic, good to have a tachometer so you can see what is
going on. If the torque converter won't stay locked up, your transmission
will not last long. You can see this if you have a tach. And an extra
transmission cooler probably can't keep up with that much added heat
generation.

If the torque converter unlocks, you will see a 100 to 150 RPM increase.
Based on what I have seen with my full size Chevy/GMC Vans.

Lordy, I love religious questions on RAS!!! :-)

Dunno your location/country/towing geography, but I'm a fan of KISS (as a
philosophy, I mean :-)). Others have noted availability (possible lack of
manual tranny-ed vehicles), and heat generation (in automatics) as potential
realities.

If your geography and personal philosophy permit, there's little actual need
to buy into the "massive vehicle is massively better for towing my 15 (or even
18 nowadays) meter baby," in which case a whole world of manual transmissioned
vehicles opens up to you. It's hard to get much simpler than a manual
transmission driving rear-wheels. This from someone who towed all sorts of
gliders (including 2-seat Schweizers) throughout the intermountain western
U.S. behind a 3-speed manual transmissioned, 2,600 pound, rear wheel drive,
unibody vehicle for 37 years, using the same transmission that never needed
any maintenance beyond (one time) topping up the gear lube (after 30+ years).
It got replaced - body rust - with a 4/RWD Toyota pickup (4WD insisted upon by
my wife for her donkey trailer...which the first vehicle towed just fine, too,
with both critters in it).

The 2600 lb vehicle never towed a trailer with electric brakes, and only
rarely one with a surge brake (Twin Grob factory trailer). Drum brakes all
around. I replaced brake linings approximately every 60,000 miles IIRC.

Never had an accident towing. Was rarely alarmed by the towing vehicle
dynamics. Never overheated. Rescued more than one immobilized buddy towing
with newer, more complex, vehicles. Never needed rescuing myself.

The 37-year vehicle wasn't rated for towing (I've no idea why) and - other
than the aftermarket (non-)universal trailer hitch & self-added trailering
pigtail(s), had zero mods for towing.
