Currently the accredited Herrod SCT ZF Transmission tuners can adjust the following characteristics of the 6HP26 transmission –
*
-
TCM based vehicle speed limiting
-Shift schedule, which allows changing transmission shift points and how long the
vehicle holds onto each gear in all transmission modes
-Kick-down sensitivity
-Change of shift pattern for differential gear changes
-Manual mode downshifting
-Eliminate holding second gear till standstill
-Adjust torque converter stall settings
-On-coming and Off-going clutch shift behaviour for built transmissions
-Running Line Pressure for high power applications
-Shift pressure per shift event based on actual gear
-Maximum shift time and amount of slip for each shift
-All of these pressure and time/slip settings are discrete for up-shift and downshift
-Torque limits for general transmission operation
-Torque reduction for each shift event
-Maximum transmission torque capability for built transmissions
-Torque characteristic to adapt for different viscosity transmission fluids

This is a brief point form description of the kind of effects and results that can be achieved via adjustment and calibration of the several hundred files in the transmission
