CLUTCH LINKAGE
(Manual Transmissions Only):
Jeep has used both hydraulic and mechanical clutch linkages over the years. When doing an engine conversion, it is not uncommon
to have clutch linkage changes. Many of these stock linkages can be retained with only a few modifications. However, if you would
like to improve you clutch linkage, we offer many upgrades from these stock linkages.
Jeeps 1972-1986 (Mechanical) - These Jeeps use the same type of clutch torque tube as the earlier models, except the torque
tube pivots off the bellhousing instead of the transfer case. This design consisted of a long rod that extended from the pedal
mechanism underneath the dash, through the firewall and connected directly to a clutch torque tube. This linkage uses a ball design
pivot bracket that bolts to the stock bellhousing. The clutch torque tube was supported between a pivot point on the bellhousing
and a bracket on the firewall. This assembly can be retained on most conversions with very little modifications.
When using one of our Chevy conversion bellhousings, the stock bracket can be retained. If you are using a GM bellhousing, we
offer P/N 716638 which will provide you with an adjustable pivot location on the Chevy bellhousing. This bracket kit is furnished
with a male ball stud and multiple hole location that permits the use of all the original Jeep clutch linkage components. This multiple
hole location will provide positioning for various engine locations. The kit also includes new nylon bushings to replace the original
Jeep nylon bushings. Depending on which bellhousing is being used, the push rod that extends from the clutch torque tube to the
clutch release lever will need possible modifications.
One of the biggest problems with the stock Jeep clutch linkage is its reliability on the trail. Most Jeep owners have either experienced
or seen the stock linkage fall apart when a vehicle is tweaked or twisted while 4-wheeling. The linkage has too many pivoting and
non-secured points and, when put under stress, they tend to come undone.
AX15 transmissions must use our adapter 50-8603 which includes a new front retainer for the Dana 300 transfer case. This adapter
requires the Dana 300 to be installed nearly flat when using the stock transfer case shifter. For other rotation options, which this
adapter offers, you must install our deluxe twin stick shifter P/N 403300 that allows more transfer case clearance along side the
AX15 transmission.
For NV3550 transmissions, first option is to simple modify the NV3550 stock tailhousing by drilling the correct rotation in the
tailhousing to mount the Dana 300 transfer case. If you are looking for a higher Dana 300 rotation for ground clearance, we offer
adapter kit P/N 50-8604 which allow for three rotation options. This NV3550 adapter works with transmission kit P/N 27-3530R.
This transmission kit comes with a new NV3550 transmission, crossmember adapter plate, and transmission shifter handle.
P/N 26-AX15 - New AX15 transmission P/N 27-3530R - NV3550 to Dana 300 stock rotation
P/N 50-8603 - AX15 rotation kit P/N 50-8604 - NV3550 to Dana 300 higher rotation kit
We offer bellhousing adapters for the Chevy V6 & V8 engines, the Ford 302 V8, and the AMC 6 cyl. & V8 engines.

(The Chevy and the AMC bellhousing will only work with a hydraulic clutch linkage).
A 168 tooth flywheel and clutch can be used on our GM bellhousing; however, a hi-torque starter is required, P/N 22-0001.
GM TH350, TH400 & 700R: This adapter kit was designed to allow the use of a GM TH350, TH400 or 700R transmission
to the stock AMC straight 6 cylinder & V8s. This 5/8” thick steel plate allows you to couple any one of these transmissions, utilizing
a modified flexplate (listed below), and retain the stock GM torque converter. The kit comes with the necessary hardware, crank
bushing, and flexplate spacers. Flexplates are sold separately. For the necessary transfer case adapter for your application, see
the Transfer Case Selection Chart. Each transfer case adapter will also require a crossmember support.
P/N 716138 - AMC engines to GM automatic
One of the following modified flexplates is necessary to complete this conversion:
P/N 716138-A AMC flexplate 304 & 360 (1972-87)
P/N 716138-C AMC flexplate 360 (1988-91)
P/N 716138-E AMC flexplate 258 (1972-87)
When installing an automatic into a Jeep, some additional parts will need to be considered. A transmission shifter will be required
and most applications need a flexible dipstick. We also carry a 52” long 700R TV cable under P/N 716138-KD and for the TH350
transmissions a 52” long kick down cable under P/N 716138-KD1
