TRANSMISSION OPTIONS: 

Available transmissions included the A230 3 speed (Slant Six only), the A833

4 speed overdrive (Slant Six and 318-2 only), and the A904 and A998/999

Torqueflite 3 speed automatics. These were coupled with either the Chrysler

7 1/4 inch rear axle (for Slant Six coupe and sedan, non-towing applications)

or the Chrysler 8 1/4 axle for the wagon, heavy duty, and V8 versions. Axles

were available in 2.45, 2.76, 2.94, and 3.23 to 1 ratios, depending upon

transmission and engine. Sure-Grip limited slip axles were optional.

Torqueflites got a lockup torque converter in 1978 for non-heavy duty

engines.  Police Package Diplomats with the 360 V8 were equipped with the

virtually indestructible 727 transmission.

  

BODY CODE PLATES: 

These plates are located on the left front fender, wheel housing or the

left side of the upper radiator support.

The service manual is unclear about the placement of some characters,

or whether or not Row 1 is at the top or at the bottom of the Body Code

plate.  It directly contradicts itself more than once. Pre-1981 Mopar

Body Code Plates were 6 rows high and 23 columns wide like

below:

A A A   B B B   C C C C C C C C C C C C C C C

the first.
