Advance Adapters AX15 - Manual (Page 57)

AX15 transmission & NP231 transfer case.
1980-86 Jeep replacements:
The AX15 is longer than most of the 4 and 5 speeds found in these vehicles; however, the AX15 is an excellent upgrade to these
drivetrains. The adapter kit we offer for this transmission is .750” thick and allows for a couple of rotations of the Dana 300 transfer
case.

Chevy and Ford conversion adapters:
Along with the Jeep engine options for the AX15 transmission, we also offer a full bellhousing for the Chevy V8’s and an adapter
plate for the Ford V8’s.
When converting to a Chevy engine our new GM conversion bellhousing uses a new slave cylinder, P/N 716213 , that is mounted
externally.
When converting to a Ford engine, we manufacture an adapter plate that requires the use of a stock Ford bellhousing. Since the
AX15 has the hydraulic linkage, we recommend obtaining a 1987-88 F150 bellhousing. This bellhousing has provisions for a Ford
hydraulic slave cylinder. The adapter kit is supplied with a brass hydraulic fitting, enabling the Ford slave cylinder to have a standard
#3 male fitting for easy connection.

AX15 to 1966-77 BRONCOS:
The AX15 transmission is an ideal transmission swap for the early
Broncos. The gearing of this 5 speed is as follows: 1st 4.01:1; 2nd
2.32:1; 3rd 1.40:1; 4th 1.00:1; 5th 0.78:1, and Reverse 3.57:1.
The transfer case adapter we manufacture for this transmission uses an adapter plate and spud shaft that couples to the Ax15
transmission. The adapter plate offers two rotation options for the Dana 20 transfer case: the stock rotation which is 42 degrees
and a higher rotation of 34 degrees. The higher rotation may require a body lift for proper clearance. The transfer case adapter
comes with a transfer case shifter linkage bracket which only fits the “T” style shifter.
The stock Ford bellhousing will also need to be adapted. The AX15 has an input shaft length of 7-7/8”. We manufacture an adapter
plate that bolts to the front of this transmission. This adapter provides you with the proper indexing and bolt pattern to couple to
the stock bellhousing. Another consideration is the clutch disc spline. The stock Ford is 1-1/16” 10 spline, and the Ax15 is 1-1/
8” 10 spline.
The new crossmember for the AX15 transmission must also be used. Since this 5 speed does not offer angular support pads
and our adapter is two short to have these provisions, we designed a new crossmember support for the new transmission. Our
new crossmember bolts to the stock crossmember frame hole and includes a new rubber support. The crossmember is designed
to fit both stock exhaust and header applications.
NOTE: This crossmember will require some additional modifications when
using an Atlas transfer case.
