Torque Converter
 

Does a higher speed TQ, say 2400 or so load the engine at an idle less than a stock converter?

In a word.....YES! If you have a hotter camshaft, the looser converter will let you idle at the light, without stalling. :chevy: LONGHORN

Yes by a considerable amount. Alot of stock converters are in the 1200-1500rpm range.

Even a 2000 stops alot of the creep from the convertor trying to fluid lock.

This for a 3 speed auto.
Personally I like to have my converter stall to be lower then highway rpm. I did a 3500rpm stall when highway rpm was 2800 at 70mph. Sure it was very snappy, and had passing power at any point. I just couldn't haul anything with the truck besides ass.

For a 4 speed lock up like a 4L65E. The above doesn't really apply except in terms of towing or hauling alot of weight.
