FUNCTION CHART
| Name | Function |
|---|---|
| Torque converter regulator valve | In order to prevent the pressure supplied to the torque converter from being excessive, the line pressure is adjusted to the optimum pressure (torque converter operating pressure). |
| Pressure regulator valve Pressure regulator plug Pressure regulator sleeve |
Adjusts the oil discharged from the oil pump to the optimum pressure (line pressure) for the driving state. |
| Front brake control valve | When the front brake is coupled, adjusts the line pressure to the optimum pressure (front brake pressure) and supplies it to the front brake. (In 1st, 2nd, 3rd, and 5th gears, adjusts the clutch pressure.) |
| Accumulator control valve | Adjusts the pressure (accumulator control pressure) acting on the accumulator piston and low coast reducing valve to the pressure appropriate to the driving state. |
| Pilot valve A | Adjusts the line pressure and produces the constant pressure (pilot pressure) required for line pressure control, shift change control, and lock-up control. |
| Pilot valve B | Adjusts the line pressure and produces the constant pressure (pilot pressure) required for shift change control. |
| Low coast brake switching valve | During engine braking, supplies the line pressure to the low coast brake reducing valve. |
| Low coast brake reducing valve | When the low coast brake is coupled, adjusts the line pressure to the optimum pressure (low coast brake pressure) and supplies it to the low coast brake. |
| N-R accumulator | Produces the stabilizing pressure for when N-R is selected. |
| Direct clutch piston switching valve | Operates in 4th gear and switches the direct clutch coupling capacity. |
| High and low reverse clutch control valve | When the high and low reverse clutch is coupled, adjusts the line pressure to the optimum pressure (high and low reverse clutch pressure) and supplies it to the high and low reverse clutch. (In 1st, 3rd, 4th and 5th gears, adjusts the clutch pressure.) |
| Input clutch control valve | When the input clutch is coupled, adjusts the line pressure to the optimum pressure (input clutch pressure) and supplies it to the input clutch. (In 4th and 5th gears, adjusts the clutch pressure.) |
| Direct clutch control valve | When the direct clutch is coupled, adjusts the line pressure to the optimum pressure (direct clutch pressure) and supplies it to the direct clutch. (In 2nd, 3rd, and 4th gears, adjusts the clutch pressure.) |
| TCC control valve TCC control plug TCC control sleeve |
Switches the lock-up to operating or released. Also, by performing the lock-up operation transiently, lock-up smoothly. |
| Torque converter lubrication valve | Operates during lock-up to switch the torque converter, cooling, and lubrication system oil path. |
| Cool bypass valve | Allows excess oil to bypass cooler circuit without being fed into it. |
| Line pressure relief valve | Discharges excess oil from line pressure circuit. |
| N-D accumulator | Produces the stabilizing pressure for when N-D is selected. |
| Manual valve | Sends line pressure to each circuit according to the select position. The circuits to which the line pressure is not sent drain. |

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
