Not always. Some issues are gradual and progressive. Minor fixes if you catch them early. Like I said, it's just a hunch, and I'm basing this on past experiences with GM's . . I could be way off here. I had a Cutlass that would slip under heavy torque, and I let it go too long. Eventually, I lost the gears one by one, and it all started because I had a small leak I didn't attend to
