Transmission Fail 3.0 duramax

[Lonnie Marco]

My transmission Violently blew up

2020 with 37500 miles has the 3.0 duramax was pulling a little uhaul motorcycle trailer with my roadglide at 60mph cruis was on in south Florida pretty flat felt like I got smashed into by a semi

Anyone else had this happen

The 10 speed has been pretty solid, not too many posts about issues. Especially not catastrophic failure. But it can happen to anything unfortunately.

Blew up, as in the case came apart too? Seems strange to me. I wonder if something outside the transmission caused the damage? How's transfer case? Are your driveshafts still intact?

I wonder if the cooler lines for the trans have the same issue in Silverado’s as they do on the tahoes with the duramax. But I haven’t heard or seen anyone mention any kind of issues with the 10 speed until this.
