DTC P1736: Problem in Shift Control System Honda Element I

1. Shift Solenoid Valves B Stuck OFF
2. Shift Solenoid Valve E Stuck ON
3. Shift Valves B and E Stuck
4. A/T Clutch Pressure Control Solenoid Valve A Stuck OFF

Note. Record all freeze data and review General Troubleshooting Information (see GENERAL TROUBLESHOOTING INFORMATION ) before you troubleshoot.

1. Warm up the engine to normal operating temperature (the radiator fan comes on).
2. Make sure that the transmission is filled to the proper level, and check for fluid leaks.
3. Drain the ATF (see step 3 ) through a strainer. Inspect the strainer for metal debris or excessive clutch material. Does the strainer contain metal debris or excessive clutch material? YES- Replace the transmission. NO- Replace the ATF (see see step 4 ), then go to step 4.
4. Clear the DTC with the HDS.
5. Test-drive the vehicle in the D position through all four gears at speeds over 12 mph (20 km/h) for more than 20 seconds, then slow down to a stop.
6. Retest-drive the vehicle in the D position through all four gears at speeds over 12 mph (20 km/h) for more than 20 seconds, then slow down to a stop.
7. Monitor the OBD status for P1736 with the DTC Monitor Tool in DTCs/Freeze Data in A/T Mode Menu for a pass/fail. Does the result indicate FAILED? YES- Go to step 8. NO- If the tester indicates PASSED, intermittent failure, the system is OK at this time. If the tester indicates NOT COMPLETED, return to step 5 and recheck.
8. Clear the DTC with the HDS.
9. Select Shift Solenoid B in Miscellaneous Test Menu, and check that shift solenoid valve B operates with the HDS. Is a clicking sound heard? YES- Go to step 10. NO- Replace shift solenoid valve B (see step «SHIFT SOLENOID VALVE REPLACEMENT»(ref-220581-S19050086332006022000000) ), then go to 16 .
10. Select Shift Solenoid E in Miscellaneous Test Menu, and check that shift solenoid valve E operates with the HDS. Is a clicking sound heard? YES- Go to step 11. NO- Replace shift solenoid valve E (see step «SHIFT SOLENOID VALVE REPLACEMENT»(ref-220581-S19050086332006022000000) ), then go to 16 .
11. Select Clutch Pressure Control (Linear) Solenoid A in Miscellaneous Test Menu, and test A/T clutch pressure control solenoid valve A with the HDS. Is the system OK? YES- Intermittent failure, the system is OK at this time. If the tester indicates NOT COMPLETED, return to step 11 and recheck. NO- Follow the instructions indicated on the HDS by the test result, but if the tester has not determined the cause of the failure, go to step 12. If any part was replaced, go to step 16 .
12. Inspect A/T clutch pressure control solenoid valve A (see «A/T CLUTCH PRESSURE CONTROL SOLENOID VALVE A TEST»(ref-220581-S26757898302006022000000) ). Does A/T clutch pressure control solenoid valve A work properly? YES- Repair hydraulic system related with shift valve E, or replace the transmission, then go to step 16 . NO- Replace A/T clutch pressure control solenoid valve A (see step «A/T CLUTCH PRESSURE CONTROL SOLENOID VALVE A REPLACEMENT»(ref-220581-S37401083362006022000000) ), then go to 16 .
13. Test-drive the vehicle in the D position through all four gears at speeds over 12 mph (20 km/h) for more than 20 seconds, then slow down to a stop.
14. Retest-drive the vehicle in the D position through all four gears at speeds over 12 mph (20 km/h) for more than 20 seconds, then slow down to a stop.
15. Monitor the OBD status for P1736 with the DTC Monitor Tool in DTCs/Freeze Data in A/T Mode Menu for a pass/fail. Does the result indicate FAILED? YES- Repair hydraulic system related with shift valves B and E, or replace the transmission, then go to step 16. NO- If the tester indicates PASSED, intermittent failure, the system is OK at this time. If the tester indicates NOT COMPLETED, return to step 13 and recheck.
16. Clear the DTC with the HDS.
17. Test-drive the vehicle in the D position through all four gears at speeds over 12 mph (20 km/h) for more than 20 seconds, then slow down to a stop.
18. Retest-drive the vehicle in the D position through all four gears at speeds over 12 mph (20 km/h) for more than 20 seconds, then slow down to a stop.
19. Monitor the OBD status for P1736 with the DTC Monitor Tool in DTCs/Freeze Data in A/T Mode Menu for a pass/fail. Does the result indicate PASSED? YES- Troubleshooting is complete. NO- Return to step 8 and recheck.

1. Warm up the engine to normal operating temperature (the radiator fan comes on).
2. Apply the parking brake, and block both rear wheels. Start the engine, then shift to the D position while pressing the brake pedal. Press the accelerator pedal, and release it suddenly. The engine should not stall.
3. Repeat step 2 in the 2, 1, and R positions.
4. Connect the HDS to the DLC (A), and go to the A/T data list.
5. Test-drive the vehicle on a flat road in the D position. Check for abnormal noise and clutch slippage. While driving, check that the shift points occur at the proper speeds by monitoring the throttle position sensor voltage with the HDS and comparing your shift point speeds and voltage to those in the table. (The throttle position sensor voltage represents the throttle opening.) Upshift: D Position UPSHIFT D POSITION Throttle position sensor voltage: 0.8 V 1st-->2nd 9-12 mph (15-19 km/h) 2nd-->3rd 21-24 mph (34-39 km/h) 3rd-->4th 28-32 mph (45-52 km/h) Lock-up ON in 4th gear 55-61 mph (88-98 km/h) Throttle position sensor voltage: 2.25 V 1st-->2nd 23-27 mph (37-43 km/h) 2nd-->3rd 39-44 mph (63-71 km/h) 3rd-->4th 58-63 mph (93-102 km/h) Lock-up ON in 4th gear 67-78 mph (108-125 km/h) Fully-opened throttle position sensor voltage: 4.5 V 1st-->2nd 39-43 mph (62-70 km/h) 2nd-->3rd 56-64 mph (90-103 km/h) 3rd-->4th 102-112 mph (164-181 km/h) Lock-up ON in 4th gear - Downshift: D Position DOWNSHIFT D POSITION Throttle position sensor voltage: 0.8 V Lock-up OFF in 4th gear 53-60 mph (86-96 km/h) 4th-->3rd 19-22 mph (30-35 km/h) 3rd-->1st 5-8 mph (8-13 km/h) Throttle position sensor voltage: 2.25 V Lock-up OFF in 4th gear 55-63 mph (89-102 km/h) Fully-opened throttle position sensor voltage: 4.5 V Lock-up OFF in 4th gear 83-93 mph (134-150 km/h) 4th-->3rd 83-93 mph (134-150 km/h) 3rd-->2nd 53-60 mph (85-96 km/h) 2nd-->1st 26-31 mph (42-50 km/h)
6. Accelerate to about 35 mph (57 km/h) so the transmission is in 4th, then shift from the D position to the 2 position. The vehicle should immediately begin to slow down from engine braking.
7. Check for abnormal noise and clutch slippage in the following positions. 1 (1st Gear) Position Accelerate from a stop at full throttle. Check that there is no abnormal noise or clutch slippage. Upshifts should not occur with the shift lever in this position. 2 (2nd Gear) Position Accelerate from a stop at full throttle. Check that there is no abnormal noise or clutch slippage. Upshifts and downshifts should not occur with the shift lever in this position. R (Reverse) Position Accelerate from a stop at full throttle, and check for abnormal noise and clutch slippage.
8. Test in P (Park) Position. Park the vehicle on a slope (about 16 degrees), apply the brake, and shift into the P position. Release the brake; the vehicle should not move. NOTE: Always use the brake to hold the vehicle, when stopped on an incline in gear. Depending on the grade of the incline, the vehicle could roll backwards if the brake is released. If the vehicle is allowed to roll backwards while the transmission is in a forward position, the engine may stall, resulting in reduced steering and braking efficiency.

Scheme 634

1. Make sure the transmission fluid is filled to the proper level (see «ATF LEVEL CHECK»(ref-220581-S17712182262006022000000) ).
2. Apply the parking brake, and block all four wheels.
3. Connect the HDS to the DLC (A), and go to the A/T data list.
4. Make sure the A/C switch is OFF.
5. After the engine has warmed up to normal operating temperature (the radiator fan comes on), shift to the 2 position.
6. Fully press the brake pedal and accelerator pedal for 6 to 8 seconds, and note engine speed. Do not move the shift lever while raising engine speed.
7. Allow 2 minutes for cooling, then repeat the test in the D, 1, and R positions. NOTE: Do not test stall speed for more than 10 seconds at a time. Stall speed tests should be used for diagnostic purposes only. Stall speed should be the same in D, 2, 1, and R positions. Do not test stall speed with the A/T pressure gauges installed. Stall Speed RPM: Specification: 2,400 RPM Service Limit: 2,250-2,550 RPM
8. If the measurements are out of the service limit, problems and probable causes are listed in the table
