Dale, this is as false as it gets. Modern converters do not "slip" as you describe. You can have a converter flash to 5000 RPM and yet idle around like a stock converter on the street, until you do a launch. Then and only then does it flash to its given flash stall. Your thinking is correct though for the 70s and 80s. But not anymore. You really need to read up or call a good converter company, because you're giving out bad information here.
