The T 400 auto was happier in the lower revving Rolls Royce V8s, except that R.R. fitted a "soft" vacuum Modulator to lower the Line Pressure to give soft sloppy upshifts. Easily sorted with a Modulator from a Pontiac. The Shadow 11 then drove much better with clean positive upshifts.
How did it fare with the earlier gearboxes like the Borg Warner 12? Same problem?
