I Have a 1979 f100 factory 302 2wd with a 3 speed with overdrive in the floor I have never seen one in a 2wd anybody know how rare they are??? Thanks

 

Never heard of any. Factory installation?

Post some pics and more info.

 

Sounds like the SROD, I believe it was offered from 1978-1987

 

+1 for it being an SROD. Did not think they were available in a dentside though..
I had one in an '84 F150, POS transmission.

 

Thanks I will post some pics this evening.

 

Would it be an Srod in a F-series?

I know there were several variations of the "3+1" overdrive 4 speed used, but I thought all F and E series used the all cast iron version with the bolt on shifter, not the integral shifter of the Srod.

Pictures of the trans and shifter would be helpful.

 

SROD is the general name for the 3 spd +OD trans. There were full 4 spd variants installed in many Ford cars in the 60s and 70s. The model years I mentioned are by memory of one of NumberDummy's posts, so I could very well be wrong, hopefully he'll be by shortly

 

Thanks again everyone I was busy last night and did not get around to make any pics I will get some up later today!

 

Understood, but...

it has always been my understanding that the "SROD" stood for Single Rail Over Drive and referred to a specific type 3 speed + OD trans, one that had the integral shifter.
From my experiences, these all had aluminum tail housings and some also had aluminum cases. All of these were weak and not suited for truck use.

I have one of the all cast iron 3+1 transmissions, with a bolt on shifter, in the '66 that is my avatar. As I remember it and the shifter came from a late 70's Granada and/or Monarch.
