ok guys got few questions too ask bout my 98 EL falcon

after driving a mates AU falcon ive notice a problem with my EL falcon.... the steering is quite stiff.. im shall the power steering is running ok cause it just had a service and they checked it and was ok......

another thing is acceleration in my EL it just seems like it has a slow take off compared to my mates AU. Would anyone knoe what i sohuld do to fix this problem or are these normal EL things...

another thing while im at it is my gear changing it seems slow and some times makes a loud sound which does not sound right... but car still runs well...

If anyone can help me it be good thanks!
