Main Description
This is a Ford New Process NP435 4-speed manual transmission removed from a late 1970s four-wheel drive Ford truck that originally had an inline 6 engine and NP205 transfer case behind it. This is a four-wheel drive (4WD) unit.
Age justification: Based on casting marks, design, and known application with inline 6 + NP205 combination commonly found in late 1970s 4x4 Ford trucks.
Very rough age classification: vintage
This transmission features a 10-spline input shaft and a 31-spline output shaft. It is being sold with the shifter as shown in the photos.
The NP435 is known for its extremely low “granny gear” first gear, making it desirable for off-road, farm, and heavy-duty use.
These transmissions were commonly found in four-wheel drive (4WD / 4x4) Ford F-150, F-250, and F-350 trucks behind various engines.
Typical NP435 gear ratios (Ford version, not confirmed):
1st (granny gear): 6.68:1
2nd: 3.34:1
3rd: 1.66:1
4th: 1.00:1 (direct drive)
Reverse: 8.26:1
You should verify gearing ratios for your exact application, but these are standard for most Ford NP435 units.
The transmission turns by hand.
A sensor is present on the transmission with wiring harness up to the plug. The wiring was cut after the plug to retain the connector as shown.
The shifter is included. The shifter collar area shows wear. No shifter pins are included.
The transmission has been drained of oil for transportation and storage.
Condition:
Sold for parts or repair. Unit turns by hand. No internal inspection performed. The transmission shows wear, grime, oxidation, and age. The shifter shows cosmetic wear including scratches and general use marks. See all photos for condition.
