What shift solenoid E does depends on the transmission. On Ford's 6R80 and 6F35/6F55 it is an on/off valve that moves a multiplex valve, so solenoid D feeds either the low/reverse brake or the 4-5-6 clutch; on the 6R140 and 5R110W it is a proportional clutch valve with separate short codes (P0985/P0986). On Saab's Aisin 5-speed E is valve S1. P0773 is the electrical code for solenoid E. GM's 2006 Allison tables flag a driver hardware fault for more than 0.1 s, cross-checked by pressure switch E, after one trip; Saab's Aisin 5-speed checks the current of valve S1 with fluid above 20 °C and shows 'check gearbox'; Hyundai/Genesis 8-speeds use it for clutch valve E and replace valve and electronic module. Ford does not use P0773.
