VibrationTransmissibility Equations, Gillespie's "Fundamentals of Vehicle Dynamics", page

Does anyone know of a "typo" and possible correction to the second one of the three transmissibility equations presented by Gillespie in his book (1992 Edition)? Two of the equations work wonderfully well for me and plot exactly as they should, but the very important "sprung mass response to unsprung mass input" equation plot is absolutely wacko. I've checked everything twice, and got the same bad results by both computer program (GW-Basic) and spreadsheet (MS-Excel).
