Is your truck that big a POS? Seems like it's broken more that it's running...
Basically, yeah.
Combination of old iron, and (IMO) shop/maintenance issues.
Transmission has had bearing noise since I took it over. Brought it up the first day.
"It's fine, it's done that since we put it in"
Last Friday it developed a gear whine, let them know about it, was off Monday/Tuesday, so they had it for 4 days.
They drained and refilled the oil in the transmission. No test drive or any sort of diagnostic work that I'm aware of.
"Good to go, just keep an eye on it"
Transmission grenaded about 3 hours into my drive.
A very expensive sounding bang, followed by lots of crunchy noises and 18 brand new neutrals.
Got lucky and was 200 yards uphill from a wide spot, so just rolled it back off the highway on the brakes.
They admitted they gambled and lost, so no skin off my ass, but it's annoying as fuck.
