40) each being in fluid communication with the first, second, and third electro-hydraulic actuators to receive pressurized hydraulic fluid output by the electro-hydraulic actuators and being in fluid communication with each other to selectively deliver pressurized hydraulic fluid to at least one shift mechanism (C3, C4, C5) of the transmission, a fourth electro-hydraulic actuator configured to receive electrical signals from the electrical control, a fourth shift valve configured to selectively deliver pressurized hydraulic fluid to at least one shift mechanism of the transmission, the fourth shift valve being controllable by the fourth electro-hydraulic actuator to achieve a first position when the fourth electro-hydraulic actuator is not electrically actuated and a second position

(98, 100, 104, 108, 114) selectively coupling the first, second, third, and fourth shift valves such that a neutral or reverse range can be achieved by the transmission when the fourth shift valve is in either the first position or the second position and a forward range can be achieved by the transmission only when the fourth shift valve is in the second position, and at least one trim system (30, 32) actuatable by the electrical control to control the rate of delivery of pressurized hydraulic fluid to at least one shift mechanism of the transmission, wherein the fourth shift valve is configured to selectively deliver pressurised hydraulic fluid to a first shift mechanism and a second shift mechanism of the transmission, wherein the first and second lands (170, 172) of the fourth shift valve define a second fluid chamber that is in fluid communication with the second shift mechanism and the second and third lands (172, 174) define a first fluid chamber that is in fluid communication with the first shift mechanism, wherein the fourth shift valve is configured to maintain the first position if the fourth shift valve is in the first position when an electrical failure occurs, wherein the fourth shift valve is configured to maintain the second position if the fourth shift valve is in the second position and a trim system is actuated when an electrical failure occurs. an electrical control configured to receive shift request signals from an electronic range selector of the transmission, first, second, and third electro-hydraulic actuators (50, 52, 54) each
