My car has 47K miles, Automatic Transmission, and has been maintained at the dealer on a regular basis. Since January I have heard a "one time" noise, coming from the front of the car as if running over a bump when in reverse out of my long driveway. I have tried warming the engine till the needle moves from cold but sometimes it works and sometimes the noise comes back anyway. It does not do it the rest of the time while driving. Dealer could not reproduce problem.I worry it is the transmission.
Noise when in reverse on 2000 Honda Accord
Asked by for the 2000 Honda Accord
FUNNY, I GOT THE SAME PROBLEM ABOUT A YEAR AGO. THIS SCARED THE SH_T OUT OF ME. I THOUGHT MY TRANSMISSION WAS GOING OUT-AGAIN.(2000 BUCKS+), LUCKILY, IT TURNED OUT TO BE ONE OF THE MOTOR MOUNTS. WHICH ONE???, THERE'S LIKE FIVE OF THEM, I GUESS. LIKE I SAID-THAT WAS A YEAR AGO AND STILL HAVEN'T FIXED IT. (YEAH I'M BROKE) DEALERS CAN'T EVER SEEM TO REPRODUCE SOUNDS, BUT THEY CAN SURE TAKE YOUR 87 BUCKS TO DIAGNOSE YOUR CAR. TAKE IT TO A SMALL TRANSMISSION SHOP YOU CAN TRUST OR CALL AROUND FOR FREE DIAGNOSTIC. DEALERS SUCK. GOOD LUCK.

Your car has very low mileage and by the sounds of things has been well maintained. I can not guess at what this noise would be without hearing the noise first hand. Perhaps you could bring the car to the dealer the night before, leave the car over night so it is dead cold, go to the dealer first thing in the morning and get a technician to do for a drive with you in circumstances that would best duplicate the noise you are hearing.
If it is a transmission mount the one that is most likely to fail when the engine load and torque is applied going forward is the front mount. Going in reverse the mount that takes the torque and load is the rear mount (back of the engine). It is a possibility!
