2015 6.7 with 60,000 miles on her .So I've noticed just recently don't know how long it's been going on but when I start the truck that there is a ticking that last for probably 3 minutes or so coming from the transmission is anybody else experience this may be nothing just curious thank you... And yes I know it's a run-on sentence doing talking. 😁 ps I also noticed today it's shifted once kind of hard from first to second and a couple days ago there were a couple hard shifts early in the morning when I left to go to work but other than that no big deal that I know of..update after I got to work it was ticking for a little bit and then stop not quite sure to make of this thank you for all your input and help in advance
