How do I know what size stall converter I have?

The only way to know the true stall speed of a converter is with a transbrake however a flash stall can give a rough idea of what it is. From a dead stop, mash the throttle and watch the tach. The tach will jump up to an rpm before the car really starts to move.

Do you need high stall torque converter?

A higher stall torque converter will let your car accelerate better because the car will be taking off at the rpm range where it is making the most power. But you don’t want a stall speed that is too high either. But the use of a higher-duration cam will allow the engine to create more power above 3,000 rpm.

What does the stall mean on a torque converter?

stall speed
Effective in-vehicle torque converter stall speed is defined as the rpm the engine can reach with the brakes locked and the transmission in gear before the drive wheels turn. Converter stall speed must be high enough to put the engine into the torque range where it can most efficiently launch the car.

What is the difference between a low stall and a high stall torque converter?

For many street trucks that are used for towing, daily driving, and performance, owners choose a lower-than-stock stall converter. While high-stall converters are the ticket for racing, they generate lots of heat due to high slip percentages and can create a huge rpm drop when lockup is engaged.

How do I know if my torque converter has a stall?

“Flash stall” is when you, from a dead stop, press the gas pedal to wide open throttle (wot). Watch your tach needle, you will see the needle jump to a certain rpm, that is “flash stall”. A drag racing-style trans brake will give you closer to the true stall speed of a torque converter.

How much horsepower can a 4L60E handle?

So, to keep things cooler they run a deep pan with a filter extension. The heavy-gauge cast-aluminum pan allows for an additional two quarts of transmission fluid, which enhances cooling under extreme conditions. 22.

How can I make my 4L60E stronger?

Now, let’s dive in:

1. Lay out the important parts on an assembly bench.
2. Rebuild with an improved, thicker sun shell.
3. Use five-pinion front/rear planetary.
4. Use a larger clutch with an input drum reinforcement sleeve.
5. Stamped Steel forward clutch apply pistons.
6. Use more clutches and larger gear band servo pistons.

What is the advantage of a high stall torque converter?

A higher stall torque converter will let your car accelerate better because the car will be taking off at the rpm range where it is making the most power.
