I hear that noise in Park, it goes away when in drive or reverse. Transmission will intermittently not go into any gear at all, but will if I turn it off and restart the car. But if it does go into gear, I hear the sound in Park before it does. Seems like if I don't hear it, it won't go into gear. Stumbles in reverse or drive if I feather the gas, like its about to stall. But if I drive it normally it's fine. The sound faintly appears while driving at higher rpms on highway or when i come to a full stop, but only sometimes. Otherwise it's mostly quiet in gear and drives normally.
The sound seems to be coming from the passenger side, near the transmission. What would cause the sound to go away completely while in gear? I did check fluid and it did seem low, did not even appear on the cold mark. So I put a little in to go to the store and get fluid, also have the plug connector famous for leaks, filter, and plate and gasket ready to install too. Also, if I leave it in park with the sound still there, and I press the S/W button, the sound does change too....
I'm sincerely hoping that it's not a dead tranny or torque converter. It was shifting fine, except for 5 minutes before the sound started happening, where slowing down in drive to a stop sign, it jerked very suddenly once. Then 5 minutes later, the sound appeared.
Is there any hopeful chance that the low fluid and possible need of a filter/plug/plate would solve this? Or could this be an entirely different issue from the tranny, like supercharger?
