AA80E AUTOMATIC TRANSMISSION: AUTOMATIC TRANSMISSION SYSTEM: P2817: Pressure Control Solenoid "H" Performance or Stuck OFF (Shift Solenoid Valve SL5)

DTC P2817 - Pressure Control Solenoid "H" Performance or Stuck OFF (Shift Solenoid Valve SL5)

SYSTEM DESCRIPTION

Based on signals from the transmission speed sensors (NT and NC), gear position is detected. If the detected gear position is different than the commanded gear position, the TCM detects related mechanical problems in the shift solenoid valves, valve body and automatic transmission.
HINT:
Gear shift position when a problem occurs in shift solenoid valve SL5:





*: Neutral





MONITOR DESCRIPTION

The TCM commands gear shifts by turning the shift solenoid valves on or off. According to the input shaft revolution, intermediate (counter) shaft revolution and output shaft revolution, the TCM detects the actual gear position (1st, 2nd, 3rd, 4th, 5th, 6th, 7th or 8th gear position). When the gear position commanded by the TCM and the actual gear position are not the same, the TCM illuminates the MIL.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK DTC OUTPUT (IN ADDITION TO DTC P2714 AND P2817)
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / ECT / Trouble Codes.
(e) Read the DTCs using the Techstream.
Result:





HINT:
If any other codes besides P2714 and P2817 are output, perform troubleshooting for those DTCs first.

C -- Go to DTC Chart Diagnostic Trouble Code Descriptions
B -- INSPECT SHIFT SOLENOID VALVE SL5
A -- Continue to next step.
2. CLEAR DTC AND PERFORM STALL SPEED TEST
(a) Clear the DTCs DTC Check / Clear.
HINT:
Write down the currently output DTCs before clearing them.
(b) Perform the stall speed test Mechanical System Tests.
Result:






B -- INSPECT SHIFT SOLENOID VALVE SLT
A -- Continue to next step.
3. INSPECT SHIFT SOLENOID VALVE SL5





(a) Remove the shift solenoid valve SL5 Disassembly.
(b) Measure the resistance of the shift solenoid valve.
Standard resistance:





(c) Connect the battery's positive (+) lead with a 21 W bulb to terminal 2 and the negative (-) lead to terminal 1 of the solenoid valve connector. Then check that the valve moves and makes an operating sound.
OK:
Valve moves and makes operating sound.
Result:






B -- INSPECT TRANSMISSION VALVE BODY ASSEMBLY
A -- REPLACE SHIFT SOLENOID VALVE SL5
4. INSPECT SHIFT SOLENOID VALVE SLT





(a) Remove the shift solenoid valve SLT Disassembly.
(b) Measure the resistance of the shift solenoid valve.
Standard resistance:





(c) Connect the battery's positive (+) lead with a 21 W bulb to terminal 2 and the negative (-) lead to terminal 1 of the solenoid valve connector. Then check that the valve moves and makes an operating sound.
OK:
Valve moves and makes operating sound.
NG -- REPLACE SHIFT SOLENOID VALVE SLT
OK -- Continue to next step.
5. INSPECT TRANSMISSION VALVE BODY ASSEMBLY
(a) Check the transmission valve body assembly Disassembly.
OK:
There are no foreign objects on any valve.
NG -- REPAIR OR REPLACE TRANSMISSION VALVE BODY ASSEMBLY
OK -- Continue to next step.
6. INSPECT TORQUE CONVERTER CLUTCH ASSEMBLY
(a) Check the torque converter clutch assembly AA80E Automatic Transmission.
OK:
The torque converter clutch operates normally.
NG -- REPLACE TORQUE CONVERTER CLUTCH ASSEMBLY
OK -- REPAIR OR REPLACE AUTOMATIC TRANSMISSION ASSEMBLY
