I have a 04 gmc duramx with Allison trans. Sometimes when I’m backing up and I pulled out of reversed to go forward it’s seem to jerk and make a loud noise and also when I come to a stop sign and it tries to drop out of the drive gear at the stop sign it’ll it’ll jerk trying to pull it out of wanting to go anybody have an idea what the problem might be ? Thanks. Ken
