We just had to have our transmission rebuilt on our 2017 Chevrolet Suburban premier at 67,000 miles. It was slipping and slow to accelerate. Going down the highway it would get stuck at 4,000 RPMs and stay there for 30 seconds or more. Thankfully we purchased an extended power train warranty and it was covered 100%. Does anyone know how long the life expectancy of a rebuilt transmission is to last? Also, we just purchased this vehicle in November of 2021 and only put 3,000 miles on it before having to get the transmission rebuilt.
