Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
HelloCustomer it is very common for the transmission to fail on this vehicle especially when it gets close to 100,000 miles. You need to start by checking the transmission fluid. If it looks dark or smells burnt then you have a major engine issue starting.
And if the fluid is ok?
Is the fluid is okay and there is no signs of problems then you either have a problem with the pressure control solenoid in the transmission or it may even be a bad or dirty mass air flow sensor on the engine. it is common for this to get dirty and cause this.
