JEEP INSTRUCTION MANUAL
FORD T18 4 SPEED 1966 & UP:
The T18 & T19 transmission can be identified by a case length of 11-7/8" and a case casting number of T18 or 13-01, and T19 or
13-09. The shift cover has a casting number of 13-01 or 13-09. The P.T.O. opening is on the right hand side towards the front of
the case and the shift cover is mounted to the top of the case with six bolts. The new shaft furnished with this kit must be carefully
compared to the original shaft removed from your transmission. The T18 & T19 transmissions required for this kit are from Ford
1/2, 3/4 and 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 index diameter of 4.848".
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. Warner gear has used two different shaft designs for the spacer between second and third gear. Some transmissions will
use a snap ring and thrust washer, while others will use a built in shoulder. Both shafts are interchangeable.
This adapter kit was developed for the early model Jeeps that had a short wheel base and are unable to use the longer T18 adapter
kits. This adapter is very similar to the original Jeep design with exception of the transmission case bolt pattern. The adapter is
available in two different styles; one for the small hole transfer case and one for the large hole transfer case. Make sure you have
received the correct adapter for your installation.
The adapter plate will bolt directly to the back of the T18 transmission using 4 socket head cap screws. The transfer case must
index onto the adapter plate in order to maintain proper alignment. A special stud bolt, seal washer and hex nut have been supplied
for the one bolt that threads into the transfer case. With the adapter in position, you must install the spacer that will locate the
original output gear in the proper location. The adapter plate must have clearance over the T18 counter shaft and reverse idler shaft.
If necessary, a small portion of the aluminum casting may need to be removed for the necessary clearance.
The oil seal that has been supplied must be installed into the new adapter plate with the open side towards the transmission.
This adapter kit is not compatible with T19 4 speed transmissions.
FORD T18 4SP TRANSMISSION TO LARGE
HOLE JEEP DANA 18 (THIN ADAPTER)
The T18 shafts had two main shaft
designs. The difference between the
shafts is the hub between the sec-
ond and third gears (both designs are
interchangeable into the transmis-
sion). Some shafts have a snap ring
and washer and others have the
spacer as part of the shaft. Most of
our shafts have the hub as part of
the main shaft. If you have the snap
ring design, just omit the washer and
snap ring when loading the gears on
the new main shaft.
