the car starts ok, but I when put it on Drive, it makes this jump ((tuumm))...it also does it when I put it on Reverse....now just today I changed the engine/trans mounts because someone told me they were the cause. now what could this be? also I have to mention, when Im driving, I can feel the automatic transmission changes, as the car pick ups speed, however, the jumps are less, much less noticeable but are there. what could this be if its not the transmission.
