I have a question about a rattle in the PTO when at idle.
2020 Kenworth T880 with Cummins and an allison rd4500 transmission.
When truck is at idle , there is an annoying rattle.
When rpm's increase almost all rattle if not all rattle goes away.
When pto is engaged and raising box , rattle completely goes away.
I have heard that it could be the lashing is out of spec.
I also have heard that combination of Cummins/Allison could have this happen.
I have never had an Allison automatic so I am open to people's opinion.
Thank you
