What Vehicles Have a TH350 Transmission? A Comprehensive Guide
The TH350, short for Turbo Hydra-Matic 350, was a hugely popular three-speed automatic transmission produced by General Motors from 1969 to 1980. Its robust design and relatively simple construction led to its widespread use across a vast array of GM vehicles. Pinpointing every single model that used a TH350 is a monumental task, but we can explore the types of vehicles and years where this transmission was commonly found.
Understanding the TH350's Prevalence:
The TH350's popularity stemmed from its durability and adaptability. It was relatively inexpensive to manufacture and maintain, making it a cost-effective choice for a wide range of applications. This led to its inclusion in everything from compact cars to full-size trucks and even some performance vehicles.
Which GM vehicles used the TH350?
This is where things get broad. The TH350 was used across GM's brands, including:
-
Chevrolet: This includes a vast range of models, from Chevelles and Camaros to full-size trucks and vans, spanning the late 1960s through the late 1970s. Specific models will vary by year and engine size.
-
Pontiac: Similar to Chevrolet, Pontiac vehicles from the same era often featured the TH350. Think GTOs, Firebirds, and various other models.
-
Oldsmobile: Oldsmobile utilized the TH350 in a selection of their cars and trucks during the relevant production years.
-
Buick: Buick also incorporated the TH350 in some of their vehicles.
-
GMC: GMC trucks and vans during this period often came equipped with the TH350 transmission.
Identifying the TH350 in a Specific Vehicle:
Unfortunately, there's no single, easily accessible database listing every vehicle ever equipped with a TH350. Determining if a specific vehicle has a TH350 generally requires:
-
Checking the vehicle identification number (VIN): The VIN can sometimes provide clues about the transmission type, although this requires familiarity with GM's VIN decoding system.
-
Consulting a vehicle repair manual: Repair manuals specific to the year and model of the vehicle will often list the transmission type.
-
Inspecting the transmission itself: If you have access to the transmission, looking for markings or casting numbers can help identify it as a TH350. However, this requires mechanical knowledge and may not be feasible for everyone.
What years did GM use the TH350 transmission?
The TH350 was in production from 1969 to 1980. However, the actual years a particular vehicle used it will depend on the model and its production run. It's important to note that GM phased out the TH350 gradually, introducing newer transmissions over time. By the early 1980s, it was largely replaced.
Were there any performance variations of the TH350?
Yes, several variations of the TH350 were offered, some tailored for higher-performance applications. These often included modifications to the internal components to handle increased torque and power. However, identifying these performance variations requires specialized knowledge.
Is the TH350 still used today?
No, the TH350 is no longer in production. It's considered a classic transmission, and its longevity is a testament to its rugged design. However, it's important to remember that parts for it might become increasingly difficult to find. Its replacement by later GM transmissions is a reflection of ongoing advancements in automotive technology.
Finding out definitively if a particular vehicle has a TH350 requires more specific information about the vehicle itself (year, make, model) and some research using the methods described above. This guide provides a general overview of the TH350's use in GM vehicles.
