Customer Question
My 2015 Mack won't...

My 2015 Mack won't turn over. I have dash lights but starter won't engage.

Mechanic's Assistant: What's the make/model/year of your truck? Engine type?

2015 Mack CHU613 Pinnacle MP8

Mechanic's Assistant: Are you fixing your truck yourself? What have you tried so far?

When I shut down last night I did not put the truck in neutral first. I received a message it was being shut down without shifting to neutral. I tried starting again but it would not. I tried disconnecting the batteries and reconnecting.

Mechanic's Assistant: Sometimes things that you think will be really complicated end up being easy to fix. The Heavy Truck Mechanic I'm going to connect you with knows all the tricks and shortcuts.

Ok

Hello and thank you for using Just Answer. My name is ***** ***** I'd like to try and help. When the unit gets shut off in gear the drive line can be torque locked and hold the trans in gear and not allow it to obtain neutral. A few things that can be done to help this is to air the unit up and release the brakes then cycle the key a few times to see if the trans goes into neutral. If it does not then try to push or pull the unit about 5 foot with the key on in order to try and allow the trans to move back into neutral. Make sure not to move the truck much beyond that limit because you can cause damage to the trans. I hope this helps. Thank you.
