I replaced the rear engine (transmission) mount today after replacing the transmission fluid and filter. The grinding noise is gone. Thanks all for the pointer. I didn't drain the torque converter. Gave up trying to get drain bolt to line up with hole after about 15 minutes of cranking. I poured 5 liters of ATF. I know I didn't follow the correct procedure which calls for pouring only 4 liters, starting the engine, shifting from P to R through N to D and back to P stopping for a few seconds in N and R, then slowley adding ATF. Now the ATF level is about 2 inches above max. How could that happen? Is it possible to trap air in the transmission? Do I need to drain 1 liter and follow the instructions or should I drain all the fluid and start over? TIA.
