just bought a used Touareg, car drives really nice but notice when coming to a stop or slow down at a light or whatever, the car jerks as if the brakes were pressed. So Im told it a transmission issue. the car shifts just fine but it seams as if when down shifting to a stop the tranny makes that clunk noise. Do you think it could be low on oil and needs to be drained put in new oil? any suggestions will help i don't want to spend money on a whole new transmission
