What is this noise?????
Ever since I've owned this jeep, its made this whistle noise or hum noise from the transmission when shifting from reverse to drive or vise versa. This noise only happens when the jeep is fully warmed up and has been driven around for a half hour or so. Mechanic thinks its the torque converter but I'm not sure. Any ideas? Its not effecting the jeep at all, just makes the noise.
