2017 Transmission Failed...

jaysolo · July 15, 2021

2017 Silverado 1500, at 135k miles, transmission blew under regular use.

Yesterday morning on the way to work, my truck would shutter while shifting in low gears (like driving over a bumpy road) and jolted during a low gear shift. 20 miles later it shifts fine up till 3rd gear and misses the shift and blows the transmission. I coasted to a parking lot, to find out my truck won't go into any gear and the transmission sounds like it has pieces bouncing around in it. Had it towed to a local transmission specialist last night and said they can rebuild it for $4300 (w/ warranty) or replace it with a OEM transmission for $4900 (w/ warranty).

From looking on this forum, it sounds like a common issue? I was really hoping to have truck that I could trust for long distance camping trips.

put the oem unit 3yr 100k nationwide warranty, for $600 seems like a no brainer

It's actually not all that common. I would go with the OEM option for warranty reasons and because never know how good the person is rebuilding.

So because it happened to you it is a common issue? I rarely ever hear of a failure, just the occasional complaint about how it acts sometimes but never a failure. Has your trans been serviced before? What kind of life has it lived? Heavy towing? Slow speed crawling in 4 lo in the mountains? Tons of mud and off road?

Torque converter failures are the common failure, that usually ends up taking the transmission out with it.

A local construction company near me has a fleet of 1500's and 25/3500's with 90% being gas engines with 6L80e and 6L90e. In talking with the service manager recently again, he says he's putting in many torque converters and new OEM transmissions per years. Most trucks are used for "work" and failures come after 100-130,000 miles.

A little history on the truck.

I got it at 119k miles in late 2020, haven't owned it for a year. It was pre-owned by one owner and it was a company truck in Texas. Judging from the large dents in the bed, I assume it was used for hauling large/heavy material and that's just the bed. It has the towing package, so I assume they used it for towing. With all this, I assume it being a company truck they drove it like they stole it (119k miles in 3 years!). Other than that, everything else looks immaculate, and it appears like it was taken care of.

For the transmission's maintenance, I did a transmission fluid and filter change 2k miles ago. Could of been its first ever transmission fluid change? Who knows? Could I have screwed it up? I hope not, been doing these things for years.

I will definitely pay the extra $600 for the OEM three year warranty with 100k miles.
