hello all, i am new here liked all this forum very useful, but I have a problem, I drive an Audi a4 2005 1.8T Quattro

while the car is in Parking, switching to D drive mode the car fells to jump, I have tried On Reverse but no problems and when am driving around 120Km/h and slowing down to 30km/h or 50 the car fells to downshift faster wish fells the car is stopped faster,

I went to 2 mechanics conclusion

First one says you have a problem in transmission, to check were problem is we have to take it out . WTF

second one says, it most be bolt or joint in the transmission or shifter that's make pressure to it and makes the car jump..

what will be the cause has anyone had the same problem before I go to an audi dealer would highly appricated
