The Iconic TH350 Automatic Transmission: Unleash Your Vehicle’s Potential

Welcome to Spoon Parts USA, your premier destination for high-quality TH350 transmissions. The TH350, or Turbo-Hydramatic 350, is a legendary 3-speed automatic transmission renowned for its robust design, impressive reliability, and broad compatibility. Originally introduced in the late 1960s by General Motors, it quickly became a favorite for a wide range of applications, from daily drivers to performance vehicles. Our new TH350 units are meticulously assembled and tested to meet or exceed OEM specifications, ensuring you receive a product that performs flawlessly for years to come.

  • Torque Capacity: Our standard TH350 units are built to handle significant horsepower, making them suitable for most street and light performance applications. For extreme builds, consider upgrading with heavy-duty components.

Applications and Fitment Information

The versatility of the TH350 transmission is one of its greatest strengths. It was factory-installed in countless GM vehicles from the late 1960s through the early 1980s, including:

Beyond its original applications, the TH350 Transmission remains a popular choice for custom builds, street rods, and drag racers due to its compact size, robust nature, and vast aftermarket support. Before purchasing, it’s crucial to verify compatibility with your specific engine, bellhousing, and vehicle year/model. Our team at Spoon Parts USA is always here to assist you with fitment questions to ensure you get the absolute correct transmission for your needs. We also offer specialized units like the SportMonster Chevy TH350 – Transmission & Torque Converter for enhanced performance.

Installation Notes and Best Practices

Proper installation is paramount to the longevity and performance of your new TH350 transmission. While we recommend professional installation by a certified mechanic, here are a few key points to keep in mind:

  • Fluid Type: Always use the recommended transmission fluid (typically Dexron-III/Mercron or equivalent).
  • Torque Converter: Ensure the torque converter is fully seated into the transmission pump before mating the transmission to the engine. Improper seating can cause severe damage.
  • Cooling Lines: Flush your existing transmission cooler and lines thoroughly to remove any debris or contaminants from your previous transmission.
  • Flexplate/Flywheel: Inspect your flexplate for cracks or damage and replace if necessary.
  • Adjustments: After installation, check and adjust the vacuum modulator, shifter linkage, and speedometer gear as needed.
  • Initial Fill: Follow the manufacturer’s recommended procedure for initial fluid fill and level checking.

Frequently Asked Questions (FAQ)

Q: What is the maximum horsepower a stock TH350 can handle?

A: A bone-stock TH350 is generally reliable up to about 350-400 horsepower in a street application. With internal upgrades like better clutches, a stronger planet, and a performance valve body, they can handle significantly more power, often exceeding 500-600 horsepower, depending on the specific modifications and usage.

Q: Is the TH350 a good choice for a daily driver?

A: Yes, absolutely! The TH350 is known for its excellent reliability, smooth shifts, and relatively simple design, making it a fantastic choice for a daily driver in many classic and even modern custom applications. Its widespread availability of parts also makes maintenance straightforward.

Q: What’s the difference between a TH350 and a TH400?

A: The TH400 is a heavier-duty transmission designed for higher horsepower and torque applications, commonly found in larger trucks, performance cars, and big-block engines. The TH350 is lighter, more compact, and generally found behind small-block engines and in lighter-duty applications. While both are 3-speed automatics, the TH400 is physically larger and more robust. You can explore our other product offerings to compare.

A: Our standard new TH350 transmissions typically do not include a torque converter unless specified.
