Ford AOD transmission throttle valve bushing check

I checked my 1989 Lincoln, and 1991 and 1990 Grand Marquis. The Lincoln's throttle valve cable was attached and looked in good shape, but I'm not 100% sure the brass bushing was installed. There is apparently a problem with the factory bushings where the disintegrate and fall off. The 1990 Marquis' cable also looked OK...the 1991 however was a victim of the throttle valve cable coming loose back in 2000 or so, causing the transmission to never shift past 2nd gear. At the time I didn't know about the TV cable problem.
