Specifications

904 Torqueflite- This transmission has a case length of 16”. This transmission is mainly found in

(1984-86) down-sized Cherokees, coupled to either a 2.8L V6 or AMC 4 cylinder. The bolt

pattern on this transmission is different than the bolt pattern on a Torqueflite

found in 6 cylinder Jeep applications. Our kits will adapt the stock transmis-

sion directly to the GM 4.3 V6. The Torqueflite 904 seems adequate enough

for the V6 engine. Although our adapters can also be used with V8 engine

installations, we do not consider the transmission and torque converter

capable of handling the power. The 1st gear ratio of the 904 is 2.45:1, 2nd

1.45:1, and 3rd is a 1:1.

When coupled to the Iron Duke 4 cylinder engine, the Torqueflite 904 has a case length of 16”. AMC had this Torqueflite casing made

with a Chevy V8 bolt pattern to fit the 4 cylinder motor. Even though this transmission can be bolted directly to a Chevy V8 engine,

we do not recommend using this transmission because the Chevy engine will require a special torque converter to be manufactured.

The torque converter could cost upwards of $500. We highly recommend replacing this transmission.

Due to differances in torque converters, these kits should only be used on 1984-86 transmissions.

Torqueflite 999 Torqueflite 904

999 / 727 Torqueflite - This transmission can be identified by a case length of 16”, and a transfer case adapter housing

(1980-86) length of 6-5/8”. These transmissions can be found behind a 258 6 cylinder or AMC V8 engine. These

transmissions were coupled to both the Dana 300 and New Process transfer cases. We have developed

an adapter plate that bolts to the front side of the transmission case, adapting it to a Chevy V6 or V8 engine.

The kit also includes an internal adapter for the torque converter. This adapter ring indexes to the Jeep torque

converter and then has a standard GM bolt pattern to couple to a factory GM flexplate, this ring also takes

care of the spacing of the converter with the new engine and adapter housing.

This installation has become very popular since the transmission can remain in the original location,

eliminating the need for driveshaft modifications. This transmission is very capable of handling the

horsepower and torque of a Chevy engine. The stock column linkage can be retained,

but it will require some fabrication. By installing a Chevy V8, you will lose the original

column linkage pivot point. An alternative to this

stock column linkage would be a cable-oper-

ated floor mounted shifter. The 1st gear ratio of

the 727 is 2.45:1, 2nd 1.45:1, and 3rd is a 1:1

and the 1st gear ratio of the 999 is 2.74:1, 2nd

1.54:1, and 3rd is a 1:1..
