when i drive over 30 mph, there is a noise, sounds like the car is wound up,not a high pitched squeal. also i feel a vibration under my feet. i started with changing the transmission filter. i put in recommended amt of fluid.about 9 liters. there is no way of knowing if it was the correct amt as there is no dipstick.. but it didn't look like there was any in there. i drove it 20 miles and no change. i added another qt, drove 10 mi & no change. took it to mechanic. he pulled the plug and let some drain out in case i overfilled. there is no diff. i only get $200-00 a month to live on and i already spent half. help please thank you

You're creating more problems than you are fixing. It sounds like your original problem may have been a bad wheel bearing but I have no idea why you started messing with the transmission.
There is a specific procedure to fill that transmission and too much fluid will do a lot of damage. It has a level check plug in the side used to get the correct level. It has to be running when filled.

my mechanic took it for a drive with me and checked the gears and said HE'D probably start with a new transmission filter . it also didn't act like wheel bearing since the noise or feel didn't change when i turned the wheel either way, the mechanic also scolded me for changing filter myself. any ideas of what to try next?
