| Description of the problem | Where do i start. This car has been more pf a pain than anything. After dealing with the steering sensitivity issue which resulted in new tires at 12000 miles, i now have a transmission issue that the dealer cannot diagnose. Beginning one month ago the car started making a loud whooshing noise eminating from the underside of the car. Thought nothing of it as i assumed that it was the new tires. Then came the transmission clunks after rapidly accelerating then decelerating. A couple of weeks ago the car, on several occassions, would clunk after starting and putting it into gear. Then the transmission would continue to shift hard through every gear, both during the upshifting and downshifting process for appx. 1. 5 miles, then it would resolve itself. I also noticed that the car often fails to accelerate when attempting to overtake other vehicles. The car has been at the dealer for almost a week now and they are unable to determine what is causing this (cannot duplicate during test drives and no codes stored in the computer). |
