I take it your Allison has a push button shift selector?
The first step is to check your transmission fluid level and confirm that it's within operating range. If it is, the second step is to pull codes when the inhibit lamp shows. Set the parking brake and simultaneously push both the up and down arrows on the PBSS until you access the DTC mode. The display on the PBSS will flash active codes first, followed by inactive codes in a sequence like this:
d1 P 07 16
With a lever SS, you just press the Diagnostics button a number of times to reach that mode.
Please post the codes. -
First let me say thank you to everyone who puts tips and tricks on here. It has saved me!
I was dealing with range inhibit, check engine, regen and flashy breakdown light the past few days on my 2012 freightliner m2. Hills especially made me shut down.
Come to find out i had a coolant issue! Nuts huh? -
