I have a bit of an odd question. I know of the C4, C5, and I have the C6 in my current truck. They are all 3-speeds w/o OD, but what is the difference between the three. I know the C6 is heavy duty, and was found in almost every truck, be it gas or diesel, but what does that leave the C4, and C5 for? What type of applications were they used in, and for which years? Were they heavy or light duty? And what is the overall difference in the three? (Gear ratios, duty load?) I've heard of them, but dont really hear much of the C4 and C5 trans, so I dont know a whole lot about them, and lookin through my FORD book, it kind of peaked my intrest...lol

-Thanks

 

Let's see, off the top of my head...

The C-4 was produced from the mid 1960's to the early 1980's

As far as trucks...they were put in the early broncos(have one in my 74 bronco)

The C-5 is basically a C-4 with a lock up torque converter that was put in the ranger and bronco2 in the mid 80's

The gear ratios are the same in the c-4 and c-6...I beleive also the same in the c-5

The c-4 and c-5 are medium duty transmissions well suited for short wheel based 4x4s. They are a bit more "fragile" than the c-6 but if cooled propertly do quite well. They also require less horsepower to turn

Also the C4 was in the mustang and I guess a lot of other applications as well.
