Have my 66 250 4X4 with an inline six. Of course trans case is divorced. Has original manual trans. Thinking of upgrading to a more modern trans. Auto or Stick. Know I can go C6 or AOD in Automatic. But in Manual what would be a good match? Would like a 5 speed. Any ideas? Not going to tow often more of a daily driver.

 

M5OD or ZF 5 spds would fit beind that engine. I would recomend the ZF before the
M5OD as it is a significantly stronger tranny. Though both will work.

 

Tremec TKO also will do the trick with the forward tower option.

NV4500 will also do it.

I will be using one of these in my crew cab.

Ranger Overdrive

I will reuse the stout NP435 and one of these as a Splitter.
