FNR5 TCC slip and/or shift solenoid E stuck off

The FNR5 transmission can be found in most Ford and Mazda front-wheel-drive vehicles and has been with us for a while. One of the most-common calls we get on this transmission in the tech center at Valve Body Pro is for a code P0741 TCC slip and/or P0771 shift solenoid E stuck off. Recently we had a 2008 Ford Fusion with this problem. Figure 1 shows the SSA (SSPCA) increasing the modulation but no drop in rpm slip.
