What Vehicles Have a TH350 Transmission? A Comprehensive Guide
The TH350, short for Turbo Hydra-Matic 350, was a popular three-speed automatic transmission produced by General Motors from 1969 to 1981. Its durability and relatively simple design made it a staple in a wide range of GM vehicles, and even found its way into some non-GM applications through aftermarket installations. Pinpointing every single vehicle that used a TH350 is an impossible task due to the sheer number and variations over the years, but we can explore the common vehicles and factors to consider.
Understanding the TH350's Prevalence
The TH350's lifespan coincided with a golden age of American muscle cars and trucks. Its robust construction made it suitable for high-performance engines, contributing to its widespread adoption across GM's diverse lineup. However, it wasn't limited to high-performance applications; you'll find it in many everyday passenger cars and light trucks as well.
Common Vehicles with TH350 Transmissions
While a complete list is impractical, these are some of the most common vehicle types and model years known to feature the TH350:
- Chevrolet: Camaros, Chevelles, Impalas, Novas, Monte Carlos, pickups, and many other models across the 1970s and early 1980s.
- Pontiac: Firebirds, GTOs, Le Mans, Grand Prixs, and various other models from a similar era.
- Buick: Skylarks, Regals, LeSabres, and other Buick models during the same timeframe.
- Oldsmobile: Cutlasses, 442s, and other Oldsmobile vehicles from the late 1960s through the late 1970s.
- GMC: Light-duty trucks and vans during the TH350's production years.
Factors Influencing TH350 Inclusion:
Several factors determined whether a particular vehicle received a TH350:
- Engine Size and Power: The TH350's robust design could handle a wide range of engine sizes and power outputs, but its capabilities were not unlimited. Larger, higher-performance engines often necessitated specific versions of the TH350 with upgraded components.
- Model Year and Trim Level: The availability of the TH350 varied depending on the model year and trim level of the vehicle. Some base models might have used a different transmission, while higher-performance or luxury trims frequently came equipped with the TH350.
- Regional Variations: Sometimes, slight differences in specifications occurred between vehicles produced for different markets or regions.
Frequently Asked Questions (PAA)
H2: What years did GM use the TH350 transmission?
GM used the TH350 transmission primarily from 1969 to 1981. While some vehicles might have used leftover stock slightly beyond this timeframe, the bulk of its production and application fell within these years.
H2: Is the TH350 a good transmission?
The TH350 has a well-deserved reputation for durability and reliability. Its relatively simple design makes it relatively easy to maintain and repair, contributing to its enduring popularity among enthusiasts. However, like any transmission, proper maintenance and care are crucial for longevity.
H2: What is the difference between a TH350 and a TH400?
The TH400 is a later, heavier-duty four-speed automatic transmission also produced by GM. The TH400 offers superior performance and torque capacity compared to the TH350, making it more suitable for high-performance applications and larger engines. The TH350, being a three-speed unit, is inherently less capable of handling high torque.
H2: How can I identify if my vehicle has a TH350?
The easiest way to definitively identify a TH350 is to locate the transmission itself and check for identifying markings cast into its casing. Consult a vehicle-specific repair manual or online resources for pictures and descriptions of the TH350's characteristics. The vehicle's build sheet (if available) will also list the transmission type.
Conclusion:
The TH350 transmission holds a significant place in automotive history, serving as a reliable workhorse in countless General Motors vehicles. While this guide provides a good overview, the precise list of models utilizing the TH350 is vast and varies by model year and specifications. Always consult reliable resources, like a specific vehicle's repair manual, for accurate information regarding your own vehicle's transmission.
