Description of Change: New software is now used for the above listed machines.

Adaptable To: The new 341-8671 Power Train Software Gp contains the following improvements:

  • The calibration of the impeller clutch has been updated in order to address occurrences of low maximum pressure on the impeller clutch.

  • The results of the calibration for the impeller clutch are now available to be viewed in ET. The results will be displayed on the "Clutch Calibration" or the "Misc Group #1" status screens.

  • The range of travel of the torque converter pedal beyond the calibrated limits has been increased in order to reduce the occurrence of "Data valid but above normal operational range" and "Data valid but below normal operational range" diagnostic codes.

Refer to Table 1 for the adaptable serial numbers and the effective serial numbers.
