Just acquired a 1965 F-600 dump truck. The transmission pops out of reverse gear. Thanks to NumberDummy for helping me decode the warranty tag, I now know it has a New Process 435 four speed transmission. Will any 2WD NP 435 out of most Ford trucks work in the bigger F-600, or is it a different transmission altogether? Any information about this will be greatly appreciated.

 

It should have a longer input shaft than most pickup transmissions. A transmission from a '65/'66 4X4 (excluding the '66 F100) or '65/'66 F350 should have the same input shaft.

 

I was hoping to avoid this thread, as there are too many variables, that takes way too much time to research. But since you've opened the can of worms...

C4TZ-7017-A .. NP435 Input Shaft-9 3/8" long / 1964 B/F/N500/700 330 / 1965/69 B/F/N500/700 240/300 I-6 & 330 / 1970/72 B/F500/700 240/300 I-6 & 330.

C5TZ-7017-B .. NP435 Input Shaft-8.991" long / 1965/72 F100/250 2WD I-6 & V8 / 1966/72 F100 4WD I-6 & V8.

C5TZ-7017-C .. NP435 Input Shaft-10.661" long / 1965 F100/250 4WD I-6 & V8 / 1965/72 F350 I-6 & V8 / 1966/72 F250 4WD I-6 & V8.

 

If you have the time, could you find the input shaft length of a 280V clark out of a '69 F600 with a 361? I looked but get easily confused by the parts book.

Do you know if any of the 5 speed transmissions you listed below (or above) have 5th gear as an overdrive or is 5th gear direct drive only?

In your other thread, in order to determine which 5 speed it is, you posted the VIN and MODEL code. I need the TRANS code.
