2013 F250 - slight 'whine' upon low speed acceleration
New to the forum, this was a great resource as I researched which model year to purchase so thank you for the knowledge.
I am also new to the 6.7 world with a new-to-me 2013 F250 (last diesel was a 2003 7.3)
I bought the truck with 138K on the odometer - very clean inside and underneath but am now compiling my list of to-do's to get it tuned up to last me a while.
I am noticing a slight whine upon light acceleration from standstill, only present through 2nd gear as far as i can tell and seems to change volume/pitch with gear changes. This leads me to think something in the transmission. I cannot detect it at higher speeds or under harder acceleration, and so far nothing I have listened to on Youtube or this forum matches what I am hearing. No trouble codes are present and transmission temp is staying in normal range.
I know a lot of noises are 'normal' but am curious as to whether anyone has experienced a similar situation and figured out the cause.
