My car is a 2001 Mercury Sable. It has the 3.0 Flex fuel engine. I was stopped at a red light and when the light changed my car would not move, forward, reverse, nothing. Sounded like I heard a faint noise when I initally pushed on the accelator to move. It will go into park but nothing else. I had it towed home. Yesterday a local auto shop came over to put the computer on it and check codes. The mechanic unhooked to plug for the transmission before connecting the computer without thinking, when he then hooked the computer up it did not show any codes. It ran a test and got no info from the torque converter. The fliud pressure showed about 15 psi. When you put it in drive and rev the engine I can hear a "whining" noise. Fluid level is good. No leaks under the car. Any ideas?
