I could be wrong, but I don't think the 727 had specific internal clutches or a special torque converter for the 440, or for any other engine for that matter.

Maybe the 603S didn't have a 727 transmission! Maybe it had an 904 or a 998. Now those would need beefing up, but surely you would just use a 727 instead...
