My 2000 Tahoe Limited is accelerating slowly until it reaches 30 mph then shifts hard enough to make the belt squeal When I try to accelerate quickly. Doesn't happen every time but I am concerned especially since I have already replaced the engine and transmission 2 1/2 years ago. I recently replaced one of the cat converters that was bad and seemed to help but it still feels like something is wrong. Any suggestions???
