 Creep at idle while in gear is a function of torque convertor slip/ vehicle 
weight/ drive gearing/ etc etc. 

 Anytime the selector in an automatic is in gear at least one clutch pack 
should be fully engaged. The only slip in the entire driveline under this 
condition is the torque convertor. 

 1) Motronic will go out of its way to maintain idle speed of around 700rpm
 2) V8's very tight torque convertor slip ratio at said 700 rpm
 3) 4.11 final drive combined with whatever the first gear drive ratio is....

 Easy to see why a V8 in gear at idle will move fairly fast on level ground.

 BTDT.... broken throttle cable 2 miles from the shop on a country 
road.....that idle creep may seem fast in your driveway but its very slllooooowwwwww 
when you're limping back to the shop.
