A High-Impact, extra-cost exterior paint, Curious Yellow paint code GY3 was ordered on approximately 9 percent of the 'Cudas. Interestingly, the hue changes from more yellow toward green with a light change. It is a desirable exterior color for any 1971 'Cuda enthusiast.
A division of the Chrysler Corporation Engineering Office issued a publication on May 11, 1970. This confidential publication was distributed internally to Chrysler divisions for the purpose of providing passenger car information to use as a resource for product advertising, press information, and a variety of internal purposes.
On June 5, 1970, a request followed the issue of these documents to maintain its security until new model introduction time. That written request came from E. D. Vosburgh who was the manager of the Engineering Standards and Data Department in the Engineering Office.
These seldom-seen internal publications emphasize new engineering and design features with potential customer appeal and show innovative leadership. Not every detail of each car line was included. Exterior and interior views of the car lines showed a general representation of the actual production versions. Many lacked details of trim and ornamentation. Photographs and illustrations of engineering and technical features were accurate and used for news releases and other publicity media.
Prints of the technical illustrations in this publication were only available to authorized users. Requests from the Public Relations offices were made directly to L. Stewart, Manager of Press Information, Public Relations Office, and all other requests were made directly to Vosburgh. There was a lot of “red tape” to navigate to become an authorized user.
New for 1971, the locking system on the steering column came with an “inhibitor ring” and instructional placard. The driver depressed this lever to remove the ignition key. This system prevents accidental locking of the steering column should anyone attempt to remove the key while the car is in motion
STYLING AND ENGINEERING FEATURES
Chrysler introduced some unique features for the new models. Regulatory demands, safety concerns, and technological advancements were contributors to these changes.
Lock Inhibitor
The new lock “inhibitor” replaced the 1970 transmission interlock feature, which prevented column locking when in “Park” (automatic transmission) or “Reverse” (manual transmission). The inhibitor ring also prevented accidental locking of the steering column if you tried to remove the key while the car was in motion. This new system resulted in smoother shifting and easier linkage adjustment. It was located directly above the ignition key cylinder. To lock the steering column and remove the key, the ring needed to be rotated clockwise and held in position while the ignition switch was placed in the locked position. Instructions were shown on the ring for one-handed operation.
Have you seen a tinted number 9 in the 10,000-place numeral? If so, expect a high-mileage car. The marking device drags violet colored ink over the last numeric tumbler. (Dodge, Plymouth and the AMC design are registered trademarks of FCA US LLC)
New Door Locks
A market survey revealed that customers preferred a keyless locking system. Plymouth added this feature to the 'Cuda. Either door could be locked from inside or outside without the use of a key by simply depressing the lock plunger and closing the door.
Tamper Deterrent Odometer
'Cudas were built with a tamper deterrent odometer to discourage the practice of “running back the mileage.” A special marking device added a violet stain on the 10,000-wheel when the odometer rotated. These stained numerals normally remained out of view until the odometer registered 90,000 miles.
Cassette Stereo Tape Player
'Cuda had a new cassette stereo tape player with a built-in recording feature. Pre-recorded cassettes could be played through the car’s speakers. Radio programs automatically recorded at the correct volume when the record mode was selected. An optional microphone was available for voice or other sound recordings. The factory assembly line microphone had a straight cord and came with lanyard. Ordering the cassette stereo also required rear speakers on hardtop models. The recording feature is believed to be an industry first, available only on Chrysler-built cars.
Self-adjusting rear drum brakes used a tension spring that activated a ratchet to set the bonded brake shoes closer to the drum to compensate for normal wear. Optional front disc brakes were part of a high level of safety on the new Plymouths. Disc brakes resist fading caused by heat build-up compared to drum brakes.

Braking System
Chrysler Corporation manufactured all master cylinders and approximately one-third of its disc calipers in-house. A more-reliable and lower-cost method of bonding disc brake linings to brake shoes was incorporated. A corporate-designed small-bore master cylinder allowed a large single diaphragm power booster to be used in place of the double diaphragm unit. A new lining material for the primary shoe and heavier ribbed front drums improved fade resistance, reduced roughness, and allowed a greater braking reserve on the drum brake system.
Transmission Changes
The part-throttle kickdown was a standard TorqueFlite feature except with the 440-6 and 426 Hemi. At approximately 10 to 40 mph, a Drive to Second downshift was automatically made when the accelerator pedal was partially depressed. The part-throttle hydraulic system had modifications to the valve body, servo piston spring, and governor for extended 2-3 shift patterns. It also included an added 1-2 shift control valve for smoother upshifts and a limit valve to control part-throttle range. TorqueFlite transmissions were all modified to reduce seal failures by using a new and improved seal that increased endurance. A new breather design also tolerated overfills without leaking.
Shift effort is lower for the 3-speed manual transmission due to two synchronizer changes: lower pointing angles and lower spring loads. Removal of the 1970 slave linkage further reduced shift efforts in low and reverse gears. Several changes were also incorporated into the 4-speed transmission, which reduced shift effort. These changes were:
• Low-gear ratio revised to 2.44:1 from 2.66:1
• Chrysler transmission fluid AQ-ATF-2848A or Dexron is now used (same as automatic transmission)
• Use of solidly bolted floor shifter levers
• Addition of a double-lever interlock provides improved shift feel
• Removal of the slave linkage resulted in easier shifting into reverse
Engine Changes
The engine changes were designed to improve drivability and control oxides of nitrogen СКАЧАТЬ
