WARNER T19 4 SPEED 1966 & UP:
The T18 & T19 transmission can be identified by a case length of 11-7/8", 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. T18 and T19 transmissions
required for this kit are from Ford 1/2, 3/4 and 1 ton trucks. The front bolt pattern on these Ford transmissions will have
an 8-1/2" x 6-1/4" bellhousing pattern with a bellhousing pilot diameter of 4.848".
Before the main shaft is installed, please verify that you have received the correct mainshaft. The splines on the end of the
mainshaft must have 27 splines. 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 qualified technician. 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.
When bolting the adapter to the main transmission case, you must use the four studs provided in the kit. A slight modification
may be necessary to obtain the proper clearance around the lower bearing cover of the stock transmission. The new seal
provided with the adapter kit must be installed with the open side towards the transfer case.
If you are replacing a transmission with a flush output shaft stickout, you will be required to remove .436 from the new
mainshaft as shown on Page 3. The adapter housing 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 skid plate will need to be slightly modified to fit under the new transmission. Two new holes may be necessary for
use with the new adapter and a slight notch may be required on the front leading edge of the skid plate for clearance around
the front drive shaft.
When this transmission is going to be used with an AMC 6 cylinder or V8 engine, you must use Jeep bellhousing No. 8133951
and Advance Adapters pilot bushing No. 716156. The clutch disc should be changed to an 10-1/2" Centerforce No. 280490
