Ive got a very stock 1965 f250 4wd with 4sp NP manual trans and divorced dana transfer case( model 24 i believe) and looking at converting to a 3sp Automatic with o/d----Anyone have any suggestions on good transmission candidate with the least amount of modifying? Thanks

 

What engine do you have? There are few(none) that bolt up to the older engines without adapters or fabrication.

 

Mornin-- thanks for checking in on my post.... I'm a 1st timer... Thought I'd give it a whirl. I've got a 352 and from what I can see , the truck was offered with a HD automatic in '65, just not mine. I'd like to do the conversion but keeping it as stock looking as possible. I spoke with CJ of "CJ's Rods and machines who said he could do the steering column with the correct shifter/ gear selector for a factory match.

 

F100/250 4WD's were not available with A/T until 1973.

Upper pic: 240/300 I-6 & 352: 1965 F100/250 4WD, 1965/66 F350, 1966 F250 4WD use a completely different engine mounting system than...

There is no overdrive auto that will bolt to an FE engine. I think I have seen an adapter plate to mate an AOD to an FE, but and AOD is anything but heavy duty.

EDIT: It turns out the below link makes adapters to run an AOD, E4OD (can be built into a tough tranny) as well as Chevy trannys such as the 700R4 (not the toughest by any means) or the 4L80E which can be built into a super strong tranny. The problem with the E4OD and 4L80E is that they require a controller to make them work.

If you don't mind me asking, why not run a manual?
