FORD C4 3SPEED AUTOMATIC TO
JEEP & SCOUT TRANSFER CASES

FORD C4 AUTOMATIC TRANSMISSIONS:

The Ford C4 automatic transmission has a case length of 11-3/16", 11 bolts for holding the oil pan in position and has a
removable front bellhousing. The bellhousing is available for 289, 302, 351C and 351W Ford engines. There is two different
main case options that are referred to as either a "flared case" or a "step case". The step case has the oil dipstick entering
the transmission case, while the flared case has the dipstick entering the transmission pan. Both models are acceptable
for use with all the Advance Adapter kits. The V8 bellhousing length is 5-7/8" and can be interchanged with the 2.8 V6
bellhousing on Bronco II and Ranger conversions. On transmissions 1970 and earlier, the pump shaft was slightly longer
and will require shortening for use with our new output shafts. The transmission should be assembled by a competent
mechanic to make sure the transmission operates correctly. The new shaft should be identical to the original shaft with
the only exception being the new splined area for use with the transfer case adapter.

Most C4 transmissions have a breather on the main case of the transmission. There are a few applications where the
breather is installed into the tailhousing. We have included with your kit a new breather for installation into your new adapter
housing only on transmissions that require vented tailhousing. The installation procedure is to drill an 11/32” hole and tap
1/8”- 27 NPT in the top portion of the new adapter housing. If this is not done on transmissions equipped with vented
tailhousings, then you will have extreme pressure and leakage out the transmission dip stick.

When installing the new tailhousing on the back of your transmission, it may be necessary to trial fit the adapter in position
and make sure that the linkage has all the proper clearance on the internal cavity of the adapter. The bolting of the tailhousing
to the main transmission may need a slight amount of grinding for proper head clearance due to the aluminum sand casting
tolerances.

All installations will require the use of a transmission cooler. The cooler can be either installed in the radiator or a remote
location is acceptable. The transmission shift control can either be Hurst floor mounted type shifter or sometimes the
exiting column shift can be modified on certain applications.
