Hi. Anyone know if there is much to swapping out a manual trans for an automatic in a 1977 f150 4x4? Seems like all you might need is a new steering column, linkage and transmission... But I'm just guessing. Some advice/experience on this topic would be greatly appreciated. Thanks!

 

you could always put in a b&m shifter on it instead of a new steering column

 

Definately need a transmission flex plate instead of the manual trans flywheel. Am not sure about the mounting of the X-fer case to the tranny or the drive shaft length. Shouldn't be to difficult going in your desired direction.

 

is it possible to put both on bill

 

Automatic transmissions require cooling through a cooler and the radiator. Do you have that?

If not your need an automatic transmission radiator, cooler, and lines.

I've seen all these for your truck at Pull a Part.

 

One thing I found when I did this to my '79 2wd was there seems to be a slight clearance issue with the x-member, making it really hard to slide the tranny into place. If you pull the enging and put it and tranny in as 1 peice it's no problem, but like I said this was a 2wd. you can get a tranny cooler from the local parts store that'll work just fine, and as much as I hate to say but the "floor" shifter from a mid 80's cavalier works great in this swap as it's a cable shifter and can be made to work just about anywhere. Just my .02 though.

 

if you have a np-435, why in the world you want to change to a crappy automatic, that is one of the strongest transmissions ever made....if you have a different trans, try and find the np and put that one in there it will bolt up just fine, and be your cheapest option
