FORD NP435 4SPD TRANSMISSION

TO T OYOTA L/C 4SPD TRANSFER CASE

FORD NEW PROCESS NP435 4 SPEED

The NP435 transmission can be identified by a case length of 10-3/4" and a case casting number of C95711 or C96391,
or C13894. The aluminum shift cover has a casting number of C11240, C97233 or C994569. The P.T.O. opening is on
the right hand side at the center of the case and the shift cover is mounted to the top of the case with 8 bolts. The new
shaft furnished with this kit must be carefully compared to the original shaft removed from your transmission. The NP435
transmission required for this kit is from Ford F100, F200 & F300 1 ton trucks. The front bolt pattern on the Ford
transmissions will have an 8-1/2" x 6-1/4" bellhousing pattern with a bellhousing pilot diameter of 4.848".

The assembled length of the transmission and adapter will vary depending on which installation you are doing.

When assembling the gears onto the new main shaft, make sure that all gears have the proper end clearance required for
oiling. Make sure that all transmission assembly work is done by a competent mechanic. All surfaces must use gaskets
to prevent oil leakage.

When bolting the adapter to the main transmission case, you must use two studs in the lower two holes of the adapter.
A slight modification may be necessary to obtain the proper clearance around the lower bearing cover of the stock
transmission. We have come across to different bolt patterns on the back side of the transmission case. The difference
is between two wheel and four wheel drive applications. If the transmission was originally used in a four wheel drive
vehicle, then the lower two holes will be spread further apart. If the transmission was originally used in a two wheel drive
vehicle, then the lower two holes will be in line with the upper two holes.

When installing the new transfer case adapter, make sure that the coupler and the output shaft do not bottom out. We have
found on occasion that a transmission output shaft may be slightly longer than we have allowed for and when coupling
into our new spud shaft, we find a small amount of interference. The adapter housing and spud shaft must be assembled
to the back of the transmission without interference. DO NOT FORCE THE NEW TAILHOUSING ONTO THE

TRANSMISSION. If assistance is needed, please feel free to call the number listed above.

The total overall length of the transmission and adapter will be longer than your original transmission and on most
conversions, will require driveshaft modifications. The adapter has provisions for mounting an optional cross member
mount as illustrated. Depending on the exact vehicle that this transmission is being installed into, you may require
modifications to the clutch linkage, overdrive shifter bracket, and transfer case control linkage.
