TORQUE CONVERTER

Most modern transmissions today use this component in their drivetrain set-up.
As the demand for more economy and lower emissions has pushed the gearbox to five,six and now eight speeds so the Torque Converter has evolved along with it.

Early Torque Converters just connected the engine to the transmission with always a slip factor of between 1000 and 2000 revolutions.  It then developed to a direct lock-up after the last gear change takes place, giving it almost no slip or loss of power.

The next development was the converter of today which now pulses the lock-up at a much lower speed as the drive is taken up, the lock-up is applied 20{dab1f3fba090b27a3a3aaea3dca2e145c63688ab4faea478c9ee7b17c03b0bef} then 30{dab1f3fba090b27a3a3aaea3dca2e145c63688ab4faea478c9ee7b17c03b0bef} and so on until full lock-up is applied

This method is much more efficient but does have wear issues.  This is why with our long experience in Gearbox and Torque Converter rebuilding we recommend oil and filter changes at least 40,000 miles and then at 24000 thereafter.  This will give your transmission a longer and more efficient life.
