Place your bets now!

The ole (new) Trailboss may have just barfed up some transmission parts....

Here's the stats:
20k miles
5.3/10speed
only driven to church on Sundays by gramma

Here's the conditions:
Rockin and rollin down I-90 into town this morning. Got Eric Church and Lizzy Hale blarin' on the stereo.
Doin bout 80-85mph.
No trailer.
30-40 mph headwind coming up off the Sound.

Here's the symptoms:
-Couple "bumps" felt in the drivetrain, thought it was wind gusts at first, honestly.
-Dash lights up like it's Christmas. ESC, parking brake, wrench light, engine light, maybe more and the incessant warnings to "service" everything on the truck.
-Dash lights go away except for engine light until I mash the skinny pedal again. More "bumps", more Xmas lights.
-Truck runs "ok" right up the speed limiter, but is late/lazy shifting with higher than normal rpms before up-shifting.
- At idle in gear or neutral, feels like the torque converter is hanging up or kicking in/out? If that makes sense.
- Accelerating from a stop = audible whining noise from the middle underneath of the truck...you know, right about where the trans lives.


Truck is supposed to get looked at this afternoon, our Equip Manager is taking it over to the dealer.

Place your bets now! What is this mystery issue?

(PS, at least I got almost 60k miles out of my 2016 Silverado 1/2 ton transmission...)

  • If the sound of choice had been Zeppelin and AC/DC, the tranny would not have had to make its objections known. :)

    The more speeds a tranny has, the more parts to break.

    Do the 10 speeds still have a turbo encabulator?


    I don't believe so. I think that got scrubbed with the addition of fully integrated muffler bearings and the new API synthetic blinker fluid requirements.
    But get this, the first reaction by the dealer was "if it is what he thinks it is, parts are on at least a 3 week backorder"
    This was before they even looked at the truck for fcks sake!
    Told our Equip Mgr to push them hard for a loaner or complimentary rental. Usually pretty good about that as we are a large customer.
    But at the dealer level, I've found that they generally prioritize repairs that are costing them extra out of pocket (IE a loner vehicle).
  • You’ve been unlucky. My 1500 Z71 has been perfect…but it’s not a “boss.”
  • I think I found the root cause, at least...

    Searching for some intel on whether there are common issues with this trans, I found this...

    " Ford took point on the (10R80) ten-speed gearbox, setting their sights on rear -or- four-wheel drive vehicles equipped with longitudinally mounted engines."

    Now wondering, should we continue taking it to the Chebbie Dealer, or just take it straight to FoMoCo?

    LOL

    One thing is for sure, as of today I'm starting to really like that clunky old, shifts like a wet fart in a bowl of mashed potatoes, 68rfe in the Brodozer!
