Test requirements for torque converter slip speeds:

"TC closed": Shifting process must be complete (wait at least 1 sec.), the Torque Converter (TC) must be closed and the
accelerator pedal value must be constant.
"TC control": Indicated values are valid for the regulating condition of the throttle converter (control). Under inconvenient
conditions (e.g. accelerating on a hill), this condition is not reached until 20 seconds after the shifting process has been
completed. During this regulating phase, slip values of up to 350 RPM can be reached.
Excessive torque slip speeds can also indicate slipping clutches or non-activated shifting elements.
