I am looking for info on what transmissions will bolt up to the current
engine in my 1983 F-150. The engine is a straight six 300, 4.9L and
currently the transmission is a 3 speed automatic. I do not know the
specific transmission number, but I can try to find it if needed. I would
like to replace it with a 4 speed automatic from a newer truck, but I'm not
sure how much trouble it would be to get it working properly. No problem
bolting it up, but I'm not sure about the electronics on some of these
transmissions. There is nothing wrong with the transmission in the truck
now, but I don't like taking the truck on the highway because it revs so
high in 3rd gear and burns way too much fuel at that high rev.
Any info on the above is greatly appreciated.

It would probably be easier to change the ring and pinion gear in the rear
end, than to change the transmission.
I don't know what gear is in your truck, but a 3.08 gear in the rear end is
great for highway, but it'll be weak on pulling power.

It would be pretty easy to put in a 4 speed AOD of the same year range
and it is not electrically controled either for shifting. The only
drawback is that tranny bypass’s torque converter in 3rd and 4th gear
so it is not a good choice if you plan to tow anything either.
Thanks for the replies guys. As far as using the truck for towing, the only
thing it would be hauling is a trailer with an ATV on the back of it,
weighing less than 700lbs altogether. Really the only thing I use this
truck for is odd trips to the landfill and a cruise into town every now and
then. I have a 1/4 ton Ranger that is basically my "daily driver". What
vehicles were the 4 speed AOD transmission installed in so I know what to
ask for when I call the local junkyards? Are there any modifications that
would have to be made to make this tranny work, or simply bolt up and go?
If I had the money to rebuild it, I know where there is a 351 Windsor engine
and transmission in an older '70's Cougar XR7. The only drawback is that
the car has been sitting for at least 20 years, and I know for a fact the
engine has less than 50,000kms. I can get the engine out no problem, and it
won't cost me a cent (sitting in my grandfathers old junkyard). But, it is
probably so full of critters nests, rats and god knows what else that it
would probably need a complete teardown and rebuild. That engine/tranny
combo would fit into my truck nicely with few modifications, but I just
don't have the time or space to do the work. That and I know that the 300
straight-six is pretty much bulletproof and I'd hate to swap it, only having
to work out more bugs.
Anyway, thanks for the info, much appreciated.

The AOD was used from about 81 to 86 or so in all trucks that normally
used a C4 3 speed unit. (usually behind 302 and such but I have seen
them behind 6’s too) I see no really big problem with the swap out and
you could even swap out the steer column too so it looks like it was
in there to begin with.

One has a OD marked on shift quadrant and the other does not.
Steering column for an automatic has the shift lever and gear indicators on
it. Standard does not.
Also, an automatic has a different pedal set. The brake pedal will be much
wider.

He already has a 3 speed automatic so this is kinda mite.
I was thinking for some reason he was switching over from a standard
transmission.
Bowing out, now.
