no, this is the big top loader 4 speed, iron case like they all are AFAIK, 420 465 etc..
i think youre thinking of those little full-aluminum side loader aluminum 4 speed plus OD in some of the 80s pickups- chevy and dodge used a few of these trannies too.. ive seen a couple before.. theres info on the net somewhere on these, i forgot the model of this tranny, hmm..
435 is definitely common tranny put in fords and and actualyl im sure it is the 435 in this one im looking at, i just forgot about ford using them so commonly, unlike GM,
i cant recall EVER seeing an F150 with a 4 speed in it, ever, i assumed it was auto just like 99% of them seem to be, until i asked and looked and i was like wow its a 4 speed, thats pretty different and wierd looking

evne the owner said auto atg first then he retracted and said manual, and that was after he actually glanced inside real quick lol.
thanks
