No.
What engine is in the Ranger? The B2 is a 2.9. Is that what the Ranger has? Even though the parts bolt on, the 4.0 has 1/3 more torque and there is a reason they used a different manual tranny when the 4.0 came out.
From what I've recently heard, the pedals from the early generation B2 won't work with the second generation Ranger.
Also, you don't have the replacement steering column and dash, so your truck will have the clues that it was an auto.
I think it's a bad idea.
I'm in the process of pulling my 5-speed out. The problem with a manual is that it is as strong as it is and that's it. An auto is a totally different beast. The case of a C4 tranny is about as big as a fat chicken and is often used behind Ford 460s in drag racing. The 351M, a weak pig, happened to have a big-block bellhousing and so these C4s built for the 351M happen to fit 460s. The nature of an auto is that it's extremely strong physically and by using Kevlar bands and carbon fiber frictions and such, you can have a tranny that weighs 70# withstand 1,000hp. The A4LD in your truck is such a beast. They don't fail from being physically weak, they fail from a couple of design flaws that are well known. Ford used the same tranny in SOHC 4.0 vehicles, including 210hp/240ft# Mustangs, who borrowed the engine which previously had only been used in trucks. That's quite a promotion for a tranny which was designed to have a 85hp 200-6 Fairmont as its most powerful recipient.
You pull apart a manual and you see gears and stuff. You pull apart an auto and there are metal drums and clutch packs and the gears are little things. Planetary gearsets are miraculous and the rest of the parts are hydraulic--like a backhoe. Servos are little hydraulic cylinders. That's what makes it work. A belt and some pistons stopping different parts of the planetaries. The whole thing is immersed in red fluid. It's cooled by fluid being constantly rotated out to a heat exchanger, which a manual is not. There are pieces in an auto which can be overpowered, but not many, and the upgrade parts are generally simple. In a high-horsepower drag car you are going to see a lot of autos because they are easy to build strong. Also, they can shift instantly and eliminate driver error.
Maybe you will get everything you want out of a swap, if you can do it. I don't consider it an upgrade. I did my swap because I needed to do something to get the truck going and had the parts. Soon after, I bought a C5 auto. Now, 8 years later, I'm finally getting around to it. I am going to pull an 8,000# gooseneck with my new project and an M50D-R1 5-speed isn't up to it. The C5 auto easily is--it's the strongest thing that will bolt to a Cologne engine, and I don't think the A4LD is far behind, properly built.
