FAQ:
What is the stall speed for a TH350 torque converter?
- The stall speed of a torque converter in a TH350 (Turbo-Hydramatic 350) transmission can vary depending on the specific converter design and the application it's intended for. Stall speed refers to the engine speed at which the torque converter begins to transfer power to the transmission. Generally, stock or mildly modified TH350 torque converters have a stall speed in the range of 1,800 to 2,200 RPM (revolutions per minute). However, aftermarket or performance-oriented torque converters can have higher stall speeds, exceeding 3,000 stall speeds and above. The stall speed is an important factor in matching the torque converter to the engine and vehicle combination to optimize performance. If you have a specific torque converter or vehicle application in mind, it's recommended to check with the manufacturer or refer to the product specifications to determine the stall speed for that particular torque converter.
What is the best stall speed for a torque converter?
- The best stall speed for a torque converter depends on several factors, including the specific characteristics of your vehicle, its engine, and your driving preferences. The stall speed you choose should match the overall performance goals and usage of your vehicle. It is a good idea to talk with the manufacturer for your specific needs or refer to a reference chart for a specific converter for your application.
What is the stall speed on a stock TH400 torque converter?
- The stall speed of a stock TH400 (Turbo-Hydramatic 400) torque converter can vary depending on the specific vehicle and application. Generally, stock TH400 torque converters tend to have a relatively low stall speed, typically in the range of 1,500 to 2,000 RPM. However, aftermarket or performance-oriented torque converters can have higher stall speeds, exceeding 3,000 stall speeds and above. The stall speed is an important factor in matching the torque converter to the engine and vehicle combination to optimize performance.
Will a TH350 torque converter work with a TH400?
- While the TH350 (Turbo-Hydramatic 350) and TH400 (Turbo-Hydramatic 400) are both automatic transmissions produced by General Motors, they have different torque converter sizes and specifications. They will interchange, both have 30 spline input shafts but will have different stall speeds based on the engine it is being applied to.
