What kind of transmission fluid does a 350 transmission take?
When it comes to maintaining your vehicle, one of the most critical components to consider is the transmission system. For those with a 350 transmission, knowing the correct type of transmission fluid is essential for optimal performance and longevity. In this article, we will explore the specifics of transmission fluid for a 350 transmission, including the types available and tips for maintenance.
What is a 350 Transmission?
The 350 transmission, commonly referred to as the TH350, is a three-speed automatic transmission that has been widely used in various GM vehicles since the late 1960s. Known for its durability and reliability, the TH350 is a popular choice among car enthusiasts and those looking to maintain classic vehicles.
Types of Transmission Fluid for a 350 Transmission
Choosing the right transmission fluid is crucial for the performance of your 350 transmission. Here are the primary types of fluid you should consider:
- Dexron III/Mercon: This is the most commonly recommended fluid for the TH350. It provides excellent lubrication and protection for the transmission components.
- Dexron VI: While this is a newer formulation, it is backward compatible with older transmissions, including the TH350. It offers improved performance and better resistance to thermal breakdown.
- Type F Fluid: Some enthusiasts prefer Type F fluid for its firmer shifts. However, it is essential to note that this fluid is not recommended for all applications, so consult your vehicle's manual before use.
Tips for Maintaining Your 350 Transmission
To ensure your 350 transmission operates smoothly, consider the following maintenance tips:
- Regular Fluid Checks: Periodically check the transmission fluid level and condition. Low or dirty fluid can lead to transmission issues.
- Fluid Changes: Change the transmission fluid according to your vehicle's maintenance schedule. This typically ranges from every 30,000 to 60,000 miles.
- Use Quality Fluids: Always opt for high-quality transmission fluids that meet the specifications for your 350 transmission.
- Monitor Performance: Pay attention to any changes in shifting behavior or unusual noises, as these can be early signs of transmission problems.
Conclusion
Understanding the right transmission fluid for your 350 transmission is vital for maintaining its performance and longevity.

What is the difference between a 350 small block and a 350 long block?
Key Differences Between Long and Short Blocks
Short blocks include, and fully assembled, the block, crank, rods, and pistons. Short blocks may include other items such as the camshaft, timing chain, and covers. Long blocks are short blocks with the heads and typically the valvetrain installed.
Does the transmission fill the torque converter?
As soon as you start the engine, the transmission will start circulating fluid and automatically fill the converter. I personally don't prefill torque converters because I could see that getting quite messy and there is no reason to, but feel free to add as much fluid to it as you want if it makes you feel better.
