This one @ ATI figures in converter slip.

Thanks all! When making a gear change the mph will change. In general going from a 5.13 going thru the traps at 7300 rpm and changing to a 4.88 what rpm drop can I expect?

7300 - 4.87% (355.5 RPM) = 6944.9
Providing the converter slip % stays the same.. (It usually doesn't)
