1983 F-150 Transmission info

Jun 14, 2005 Last reply: 21 years ago 10 Replies

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. Sharky


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. Sharky

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.

What is the difference in the steering column, if you don't mind me asking? Not quite sure I understand what you mean.

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'm gonna hit myself in the head with a hammer.

I was thinking for some reason he was switching over from a standard transmission.

Bowing out, now.

LOL, no problem dude. I kinda thought there may have been something different with the column itself. But yeah, my truck is already an automatic, and where the 1/4 ton is already a 5 speed, I don't think I need another one.

Thanks alot for both of your help, I appreciate it. Sharky
