The rpms should be lower with the 5 speed. I believe the T5's overdrive is like .62 or .68 and the AOD's overdrive is in the seventies.

OD for the T5 and AOD is about the same. The AOD is .67. There for if your TC is locking and entering OD, your highway rpm will be basically the same.

EDIT: Did some quick research and found that the V8 T5 has a OD of .68. The Motorsport version was available with a .63 OD gear.
