Truck in fluid changes and investigate subtle shudder at cruising speeds. Told them it felt like my ‘14’s shudder when AFM kicked in.
Dealer #1 : You need a new torque converter.
6 weeks later, after causing other damages to my truck, I get the truck back. Same shudder exists. New, more violent shifts and vibrations at low speed. After choice words and a few more weeks of waiting for them to replace my running boards supports, I move on to another Dealer.
Dealer #2: The cruising speed shudder is DFM. (I didn’t realize truck had it.) The TCM/ECM needs updates. Updates will solve all vibration issues.
They perform updates, truck seemed ok in lot. Not a mile down the road, SERVICE BRAKE PAD MONITOR. Dealer #1 stated brakes were at 4mm.
took truck back to Dealer #2, rear brakes at 2mm and less than 1mm.
New pads/rotors on rear, new pads up front.
truck seems good. Toggle through menus, brake monitor system is disabled. Huh? Why? Turn that sucker on : SERVICE BRAKE SYSTEM!
will not reset manually, automatically, or even after pulling negative bat cable for 30min.
Could the TCM/ECM updates the culprit?
A torque converter diagnosis for a “normal” shudder and now I’m thousands in the hole and the truck still isn’t right! Beyond pissed.
