I’ve got a 2017 limited with 64k miles that just had a transmission totally fail. Has anyone else seen this happen? I’ve averaged less than 10k miles per year and don’t tow anything. Dealership says I am 4k miles outside of powertrain warranty so nothing they can can do.
I have taken to offering a thermostat delete when doing a trans service on 6L80e. This prevents the trans from overheating, hopefully keeping the torque converter failure at bay.
