If the ECU of your vehicle requires repair or replacement, or if it needs specific programming
parameters, see Programmed Parameters below.
Programmed Parameters
Programming in the transmission ECU module affects engine speed, PTO engagement and operation,
as well as the (optional) auto-neutral system. If the ECU module is replaced, it must be
reprogrammed to reset the vehicle operating parameters. Refer to Table 5 to reprogram the
transmission ECU.
On chassis supplied by Labrie, the programming package for Allison transmissions is package #142.
Some customer chassis may have different programming packages. Refer to your local Allison dealer
for original programming packages. For further information regarding ECU programming, contact
LabriePlus.
The following pages show how Allison electronic transmission ECUs are programmed for Labrie
vehicles. Parameters shown in the following tables apply to all A
UTOMIZER™ vehicles.
