Transmission Gravely Sound
I have owned my 2012 Focus since last September. It's production date was late August. Regarding the grinding noise from the transmission I can relate to the gravely sound that occurs for me, oddly, only after I have driven on 1 particular road. The road terrain is hilly, 25mph or less curves, and is generally a road with top speed of 40mph. Driving on this road involves acceleration to go up a hill and slowing down to take a curve and then accelerating to go up a hill or braking to go down a hill. It is after I have driven on this road which is 10miles long and start driving again on a highway that involves traffic lights is when I hear the noise. When I leave the traffic light do I hear the noise but once past 2nd gear I do not hear the noise for 3-6. This is the only time I hear the noise, all of my other driving, which is light and heavy traffic, and highway driving, I never hear the noise and the transmission works fine. At 5000 miles the check engine light came on and the dealer re-flashed the computer module. The upate did not change or stop the noise after driving on that 1 road. Now have 8000 miles and the transmission is fine except for after driving on that 1 road the noise comes back. After the car sits for a while the noise is gone, but if the car only sits for say 30 minutes the noies is still there. Now is there something going on when there are many upshifts and down shifts in a short distance, I don't know. What about heat issues? I've driven the car for 300miles at 70 mph non stop and had no noise with the transmission when starting out after a stop. I hope that all of this doesn't mean that sometime in the future that the transmission will fail.
