I just changed the ATF. It shifts much nicer now, but the car is idling with a different pitch. She sounds different. I am not sure if this is normal. Has anybody else noticed a change in sound after the ATF change? I also changed the differential fluid.
I put in almost 6 quarts of ATF. (is the noise because of an incorrect fluid level?)
I put in about .7 quart of gear oil in the diff.
