What kind of transmission fluid does a 350 transmission take?
The 350 transmission, also known as the TH350, is a popular 3-speed automatic transmission used in a variety of General Motors vehicles from the 1960s through the 1980s. The 350 transmission requires a specific type of transmission fluid to function properly and maintain its longevity.
Type of Transmission Fluid for a 350 Transmission
The recommended transmission fluid for a 350 transmission is Dexron-II or Dexron-III automatic transmission fluid (ATF). Dexron-II and Dexron-III are General Motors-approved fluids that meet the specific requirements for the 350 transmission.
These fluids are designed to provide the necessary lubrication, friction characteristics, and viscosity for the 350 transmission's internal components, such as the gears, clutches, and bands. Using the wrong type of fluid can lead to premature wear, slipping, and potential transmission failure.
Fluid Capacity and Change Intervals
The typical fluid capacity for a 350 transmission is around 12-14 quarts. However, it's important to check your specific vehicle's owner's manual or service information to determine the exact fluid capacity for your 350 transmission.
As for fluid change intervals, it's generally recommended to change the transmission fluid in a 350 transmission every 30,000 to 50,000 miles, or as specified by the vehicle manufacturer. Regular fluid changes help maintain the transmission's performance and extend its lifespan.
Conclusion
In summary, the recommended transmission fluid for a 350 transmission is Dexron-II or Dexron-III ATF. Using the correct fluid and following the recommended change intervals are essential for the proper operation and longevity of your 350 transmission.
What transmission does a 350 small block have?
The TH350 is an automatic shift, three-speed transmission.
Can I use Dexron VI in a TH350?

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.
Is DEXRON VI the same as ATF?
Valvoline Dexron VI/Mercon LV ATF is the full-synthetic automatic transmission fluid that has been uniquely engineered to meet and exceed the requirements of the General Motors Dexron VI specification and is officially licensed and approved by GM.
Does it matter what transmission fluid I use?
Choosing the correct transmission fluid is critical to insuring the maximum performance and fuel economy from your car.
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.
