The Dodge TCU has four different transmission modes, which can either be set in MTune, or from an analog channel (Transmission Drivemode), see MTune 8HP Settings for options.
STREET (1)
Slower shifts, more converter slips, easier to drive.
SPORT (3)
Moderate shift speeds, little less converter slips, starts to become fun to drive.
TRACK (5)
Faster shift speeds, not much converter slips, now we are talking about fun to drive.
DRAG (10)
Everything set to max, very little converter slip (if anything at all), pure drag racing mode and enables the 8HP transbrake feature.
See, Transmission Drivemode with example how to setup.
