Do your research first!
I purchased my 2016 Chevy Suburban with 65k miles on it for over $40k in 2021, made it 93k miles before needing complete transmission rebuild, estimated cost $6-7 thousand dollars! Not an easy pill to swallow. After researching, you will find in this year/model a bad design from GM. No recall or special coverage fixing their bad design. Multiple lawsuits with GM and still no special coverage. Very disappointing. Have no choice but to fix, do not plan on keeping this vehicle for future, newer models they fixed the issue so hoping I can find one for a somewhat reasonable price. Do better GM!!!
