2009 Ford Taurus Q&A
2009 Ford Taurus Question: Tachometer (Transmission) problems
I have a 2009 Ford Taurus X Limited AWD. When travelling at approximately 70 to 75 Kilometers per hour with an engine rpm of 1500 to 2000 the tachometer will occasionally buzz momentarily and the tach needle will bump up to approximately 2000 rpm and then return to normal. I have had the vehicle to the Ford dealership 5 times to repair this problem. They have replaced the instrument cluster, a computer chip, a valve in the transmission and some transmission hydraulic lines and still no cure. Am I going to have a transmission failure????? There are approximately 30,000 kilometersw on the vehicle. Ford says there are no codes. It happens almost every time when maintaining a fairly constant speed of between 70 to 75 kilometers per hour. - WRB
