So my ram is a 2015 quad cab sport with 50k miles. I have noticed a few things about the 8 speed trans:
- the below has been happening roughly the last 7500 miles (or as far as I can remember) but has not gotten worse
- slight flare of 200 - maybe 300 rpm only on the 3/4 upshift, all other shifts are butter smooth up/down
- happens only below ~ 2000 rpm whether warm or cold
- never towed with the truck, just casual daily driving and taking the occasional mattress to the dump (no off-roading, I have a ram-charger on 37's for that)
- light throttle seems to be the usual way I can make the flare? re-occur
- under minimal rpm, it rarely happens
- does not feel like a slip, truck keeps accelerating under power, when I test my theory and get the truck to shift at 3k+ rpm, it is fine and smooth on the 3/4 upshift
Tried to find a similar case and cant quite find anything else fitting the mold of my description.
I did read about someone having a rare flare on a 2/3 upshift and someone mentioned air purging? But hard to compare
Oh, no bangs or clunks or engine lights, trans temp stays normal operating temp and has never overheated. Tried a re-learn, but still persists.
Any thoughts greatly appreciated, thank you!
