What is a turbo 350?

The Turbo Hydra-Matic 350, commonly known as the TH350 or Turbo 350, is an automatic transmission that was manufactured by General Motors. It was a popular and widely used transmission in many GM vehicles, particularly from the late 1960s through the early 1980s.

Key characteristics include:

* Three-speed design: It had three forward gears and one reverse gear.

* Relatively simple design: Compared to later automatics, it was mechanically simpler and generally more robust.

* Wide range of applications: It was used in a variety of vehicles, from passenger cars to light trucks.

* Relatively inexpensive to maintain and rebuild: Its simplicity contributed to its affordability for repairs.

While popular and durable, the Turbo 350 was eventually superseded by more modern designs offering improved fuel economy and performance. However, its simplicity and availability of parts mean it remains popular in the restoration and hot rod communities.
