  Versions of the Plymouth Valiant can be found all over the world from Mexico to New Zealand. The 1967 version of the Valiant featured several engine styles with a couple transmission options to meet increased horsepower and torque requirements. The greatest advances in automatic transmissions at this time were made by designer and manufacturer TorqueFlite. The company developed transmissions for Chrysler that were so reliable that the designs were used in every conceivable vehicle from compact cars to heavy-duty trucks.

This particular "base" vehicle model did not offer the more sophisticated transmission options of other Plymouth Valiant models. According to the Plymouth enthusiast website Valiant, over 100,000 of this model were sold in 1967.
  
  

225 Slant Six Transmission Options

273 V8 2-Barrel Transmissions

• The 273 V8 2-barrel was fitted with either a three- or four-speed manual transmission. A four-speed automatic transmission manufactured by TorqueFlite was also available for this model. According to car and truck website All Par, the TorqueFlite automatic transmission was among Chrysler-Plymouth's most reliable components and is utilized in a wide variety of vehicles for many years lasting through the 2001 Neon.
  
  

273 V8 4-Barrel Transmissions

• The heavy duty V8 4-barrel was fitted with a four-speed manual transmission or a four-speed automatic transmission built by TorqueFlite. Gear shifts for automatic transmissions built at the time of the 1967 Valiant were actually placed on the dashboard. Automakers utilized this "push button" style in part to break drivers from the habit of reaching to the floor to constantly shift gears, which is necessary with manual transmissions.
