When i start the car in the morning cold (sitting overnight), and i shift into reverse from park, i hear a "cling" sound. Could this be the front flex disc? Also when the car is warm (after driving for 30 min on the freeway)and i come to a complete stop, i shift from reverse to drive, the car "jumps" alittle. Are both of these problems due to the flex discs? transmission mounts??...How could i make the "cling", and "jump" go away??...What are signs of worn flex discs?

Thanks in advance.....
