the AOD's infamous 'chug-a-lug' third gear will drive you nuts

It is more a matter of final drive ratio in rear axle than the "chug
a lug" tranny. If your rear axle ratio is around 3.55 or taller with
a OD and that 4.9, it will not tow well but it you gear it up to 4.10
or so it will do a good bit better. It will not be a barn stormer but
it should do okay up to 5000lbs or so with deeper gears (if you want
to go through the trouble of changing them) otherwise I would limit
myself to popup campers as it sits now.

you're not REAL familiar with how the AOD is set up, are you ?

Probaly a lot more familar with transmisson and gear limitations than
you think! I actually have a working 83 AOD in the barn right now.

oh, wow
I'm impressed
so tell me what the power flow is in an AOD in 3rd................this bears
directly upon the problems found when towing with one

Gee I did not know there was "bears" in a AOD. That is news to me!
You are just looking to start something here and if I answer your
question, and pass your "test" then what gonna be the next one?

hey, YOU are the one who claimed extensive knowledge of the workings of the
AOD
if you don't know, just say so and we'll forget it.......BUT
I notice you've posted your 'knowledge' to all the truck groups the last few
days, including that howler about the 'slug of freon or oil' in the
evaporator of a GM AC ..............
your kind comes and goes with regularity around here.......now, about how
the AOD works............ball's in your court, bucko.

You still have your owner's manual? It'll tell you in plain language what
the towing capacity is with your engine, transmission, and gear ratio
combination.

The trouble is that some of the owners manual tow ratings are more
dream than reality as they do not really factor in wind drag from big
cross sectional trailers nor hilly terrain or whether for highway
speeds too. A 4.9 with automatic and stock gearing is going to be a
marginal tower at best. There is not much reserve power in that truck
for towing as it sits.

What gear ratio in the differential? It makes a big difference.

Ask a trailer salesman. You can probably pull 42 foot fifth wheel
according to him.

I have a '95 f-250 with a 5.8 and 3.55 gears. I tow a 26' 5th wheel.This unit
weighs 5500# dry. I tow it pretty good on the interstate, but have a little
trouble maintaining speed on the highway in the hills.It will depend largely
on what size camper you want.I would recomend the small ultralight travel
trailers,24 ft or less.I have a freind that has a 22' light wt camper and
pulls with the 4.9.His truck pulls it ok, but is not a speed demon.
I have a question.If I go to a 3.70-3.8000 series gears, will I gain a good
bit of pulling power?
Thanks, Mikey
