hello everyone i had as question about the transmission, i have a 93 190e 2.3, it has about 204000 miles on it, it was given to me by someone i have no clue what they every did to the car and such, but when i drive it the car will kick a little when changing gears, i can hear the noise in the back of the car, also i put the car in neutral and gas it a little and i can hear a noise from the back of the car, im just wondering if is this the transmission or is this maybe some where in the rear differential?
