9.15.6 Transmission Solenoid Valves

The transmission is shifted via six solenoids. Three

solenoid valves (Y1, Y2 and Y3) are contained in an

UPPER spool-type solenoid cartridge assembly (valve

body) (Fig. 9-96, 1).

Figure 9-96 Upper and Lower Transmission

Shift Solenoid Locations

The remaining three solenoid valves (Y4, Y5 and Y6) are

contained in the LOWER spool-type solenoid cartridge

assembly (valve body) (Fig. 9-96, 2). While each 12-volt

solenoid coil at the transmission is the same, the internal

wiring to the solenoids is different and connected so that

the various transmission clutches can be actuated via

input from the transmission shift control switch (travel

select lever).

By placing the transmission shift control switch (travel

select lever) in any given position, a combination of

solenoids are activated, which, in turn, engage a

combination of internal clutches. (Refer to Section 9.15.6,

a. “Travel Select Lever and Wiring Harness Testing” and

Section 9.15.6, b. “Upper and Lower Transmission Valve

Body Solenoid Testing.”)

If the transmission is not shifting properly, the

transmission shift control switch (travel select lever),

wiring harness or transmission shift solenoids should be

checked in order to determine which component is

defective. Specific information to determine which travel

position and corresponding component is not responding

can be found by referring to Section 9.8.1, “Transmission,

Forward First Gear Circuit,” and subsequent circuits and

troubleshooting charts. Replace a defective component.
