How to choose the right torque converter for your car?

For the best performance you want to choose a stall that is somewhere near the peak torque of the engine in question. Engines with more low-end toque usually increase stall speed. The exact same converter used on an engine with lower RPMs will stall. Another thing to consider is the resistance put on the engine.

What’s the Flash Speed on a torque converter?

Flash occurs the instant you release the foot brake and the rotating inertia (which is “stored” in the engine flexplate) is released. In many cases, this flash speed can be anywhere from 500-2,500 rpm higher than the foot brake stall speed.

What should the stall speed be on a torque converter?

Stall speeds are a great way to rate torque converters performance level. The range level will tell you a lot about what to expect from the torque converter. In you select a 2700-3000 converter, it should be able to footbrake stall the torque converter to about 2700 rpm considering the automobile setup.

What does 100 rpm of torque converter slippage mean?

Usually, 100 rpm of converter slippage equals a loss of one and a half miles per hour through the traps. Trap speed rpm will tell you if the converter is operating efficiently when going through the traps. Typically, 100 rpm of torque converter slippage equates to a loss of 1 1/2 mph through the traps.

When does a torque converter start to stall?

As engine speed increases, fluid flow is directed through the stator to the turbine, which drives the turbine and transmission input shaft to get you moving. The point at which the impeller begins to drive the turbine is known as stall speed. Most stock torque converters “stall” at around 1,500 to 1,900 rpm of engine speed.

How is a torque converter identification catalog organized?

The Catalogue is organized in the following sequence; Manufacturer e.g. Chrysler, Ford, General Motors etc (alphabetically), then by Transmission Type (again alphabetically) and finally by Converter Code (TCS Code).

What is the torque ratio on a Dia torque converter?

How do they check a torque converter?

How to Test a Torque Converter Start the engine and let it warm up First, you should start the engine and let the transmission oil warm up to around 40 degrees. Move shifter into gear Now you can try to apply the drive gear and listen carefully if you can hear any signs of noise from the torque converter. Test drive

What are the signs of a failing torque converter?

6 Signs of a Failing Torque Converter Loss of Acceleration. If your vehicle feels more sluggish than normal or it is physically shuddering when you step on the gas pedal-as if it’s struggling to accelerate as Slipping Between Gears. Automatic vehicles should shift smoothly between gears. Vehicle Won’t Shift at All. Transmission is Overheating. Transmission Fluid Leak.

Is the torque converter considered a part of the transmission?

A torque converter must be used when running an automatic transmission and is sometimes considered part of the transmission . The torque converter is a separate entity from the transmission and serves three primary functions.

What are the advantages of a torque converter?

Convenience. Torque converters allow a car to start and stop without user intervention.
torque converters act as a sort of continuously variable transmission.
Flywheel Effect.
Infinite Slippage.
Fluid Reservoir.
