Big Chief Car Pontiac Transmission
Introduction
The Big Chief car Pontiac transmission is a three-speed automatic transmission that was used in Pontiac cars from 1955 to 1964. It was also used in some Oldsmobile and Buick cars during the same period. The Big Chief transmission was known for its smooth shifting and durability.
Design
The Big Chief transmission is a conventional three-speed automatic transmission. It has a torque converter, a planetary gearset, and a hydraulic control system. The torque converter provides a smooth transition from a standstill to cruising speed. The planetary gearset provides three forward gears and one reverse gear. The hydraulic control system controls the shifting of gears.
Operation
The Big Chief transmission is operated by a shift lever that is located on the steering column. The shift lever can be moved to the following positions:
- Park (P)
- Reverse (R)
- Neutral (N)
- Drive (D)
- Low (L)
When the shift lever is in the Park position, the transmission is locked in place and the car cannot move. When the shift lever is in the Reverse position, the transmission engages the reverse gear and the car moves in reverse. When the shift lever is in the Neutral position, the transmission is not engaged and the car can move freely. When the shift lever is in the Drive position, the transmission engages the drive gears and the car moves forward. When the shift lever is in the Low position, the transmission engages the low gear and the car moves forward at a slow speed.
