SOURCE: where is the location of Honda accord A/T clutch pressure Control solenoid Valve B

You didn't menyion the year or engine size of your vehicle in order for anyone to be able to give you a picture of at least thell you its location. Depending on the year however I do know that in Honda's solenoid A & B come as a assembly and need to be replaced as one unit but again will need to know the year and engine size to be sure this is the case for your year. Also if it's a DX, LX or something of that nature as well. Also are you geting any trouble codes like is you engine light on and is the D3 or D4 (if eqiupt with a light) flashing ?

I have Honda Accord 2001and I put the scanner this Code come out p1768 what this means


Possible causes
- Clutch Pressure Control Solenoid Valve harness is open or shorted
- Clutch Pressure Control Solenoid Valve circuit poor electrical connection
- Faulty Clutch Pressure Control Solenoid Valve

Has to do with the solenoid or wiring to the solenoid inside the transmission. You should have the problem addressed at a transmission shop.

How to fix the automatic transaxle malfunction


Possible causes of OBD code P0780
- Low transmission fluid level - Dirty transmission fluid - Faulty shifting solenoid valve - Shifting solenoid valve harness or connectors - Shifting solenoid valve circuit is open or shorted The Error code is generally activated on detection of the following conditions: The P0780 codes is detected when no rotation change occurs between input (turbine revolution sensor) and output (revolution sensor) and shifting time is long or when shifting ends immediately or when engine revs up unusually during shifting.So check out these points and see if any are all help keep me posted

P0740 Honda - Transmission Lock-Up Control System Fault Possible causes
- Low transmission fluid level
- Dirty transmission fluid
- Faulty torque converter clutch solenoid valve
- Torque converter clutch solenoid valve harness is open or shorted
- Torque converter clutch solenoid valve circuit poor electrical connection

Tech notes
On some Honda vehicles the P0740 code may be set by an overheating torque converter problem which is caused by an insufficient flow to the torque converter release circuit.

P0740 Honda Description
The torque converter clutch solenoid valve is activated, with the gear in D4, by the Transmission Control Module (TCM) in response to signals sent from the vehicle speed and the Engine Control Module (ECM). Lock-up piston operation will then be controlled. When the torque converter clutch solenoid valve is activated, the torque converter lockup clutch will engage creating a 1 to 1 RPM ratio between the transmission input shaft and the rotational speed of the torque converter.
Lock-up operation, however, is prohibited when A/T fluid temperature is too low.
When the accelerator pedal is depressed (less than 2/8) in lock-up condition, the engine speed should not change abruptly. If there is a big jump in engine speed, there is no lock-up.

I have a 2002 honda accord, V6 with 42,000 miles,,,yes,,,42,000 miles The check engine light went on, the dealer checked the code "p0780" Replace transmission. Can this be right?


The code you have P0780 is an internal hydraulic problem in the transmission. I did some research on this trouble code and the repair manual Say's to replace the torque converter clutch solenoid valve/shift solenoid valve A, and the A/T clutch pressure control solenoid valves A and B.

In plain English these are the shift solenoids and torque converter solenoids. These solenoids control the fluid flow to the transmission and if they are not working properly then p0780 will set.

The bad news is the repair manual Say's to replace these solenoids and if the problem is still present then replace or overhaul the transmission because the problem is internal.

Most repair shops are not going to take the risk and just replace the solenoids, they will replace or overhaul the transmission.

Shift solenoid not engaging overdrive which


    The valve body contains six solenoid valves:
  • three PWM solenoid valves (pulse width modulation solenoid valves,
  • two shift solenoid (on/off) valves,
  • one main regulating valve (variable force solenoid).
The individual clutches and bands are supplied pressure from the PWM solenoid valves and the shift solenoid (on/off) valves and thus the gears are shifted.
The PWM solenoid valves allow direct actuation of the clutches and bands to ensure extremely smooth gear shifting through precise pressure regulation.
The shift solenoid (on/off) valves switch the hydraulic path to the clutches and bands, reducing the number of required modulating valves.
The main regulating valve (variable force solenoid) ensures that sufficient hydraulic pressure is available in all operating conditions.
PWM solenoid valves 1-3 PWM solenoid valves 1, 2 and 3 control the pressure to the bands and clutches.
Shift solenoid (on/off) valves 1 and 2 The shift solenoid (on/off) valves switch the different oil passages in the valve body to direct the pressure to the individual clutches and bands.
The use of the shift solenoid valves are needed for direct actuation of the individual clutches and bands.
Main regulating valve The main regulating valve (variable force solenoid) controls the required main line pressure for the individual transmission ranges.
The main line pressure is controlled dependent on the current engine load.
----------------------------------------------------------------------------------------------------
Electronic synchronous shift control (ESSC)
Control of shift operations
During a shift operation certain elements are released while others are actuated. Ideally this process takes place simultaneously (synchronously) to avoid jerky gear shifting.
The time for the shift operation should remain within the time limits provided.
When the shift operation is controlled conventionally, the pressure build up and reduction at the shift elements are set and defined for ideal conditions (synchronous shifting).
As there is no way of influencing the control in the event of different levels of wear in the shift elements, when the transmission has been used for a fairly high mileage it is possible that the pressure build up and reduction may no longer be synchronous.
The result or premature pressure reduction at the element to be switched off is an unwanted rise in the turbine shaft speed as the element to be switched on cannot transmit the input torque.
The result of delayed pressure reduction at the element to be switched off is an unwanted decrease in the turbine shaft speed as both shift elements transmit the input torque. In the process the torque is transmitted to the transmission housing through internal locking.
In both cases a **** will be felt during the shift operation.
In addition, wear in the shift elements leads to a lengthening of the shift operation. Therefore, shifting takes longer when the transmission has accumulated a higher mileage.
Control of shift operations with ESSC In the 4F27E automatic transmission electronic synchronous shift control (ESSC) is used.
ESSC monitors the shift operations and is able to adapt to the wear in the shift elements over the life of the transmission.
This is possible since the shift elements are actuated by modulating valves.
The system monitors the shift time whether the shift operation is synchronous.
If the PCM detects a deviation from the stored values for the shift time and synchronization of the shift operation, the pressure build up or reduction is adapted accordingly.
Throttle position (TP) sensor The TP sensor is located on the throttle body.
It supplies the PCM with information about the position of the throttle plate.
It also detects the speed of actuation of the throttle plate.
The PCM uses the signals for the following functions among other things:
  • to determine the shift timing,
  • to control the main line pressure,
  • to control the torque converter lock-up clutch,
  • for kickdown.
In case of absence of the TP signal the engine control uses the signals of the MAF and IAT sensors as a substitute signal. The main line pressure is increased and hard shifts may occur.
Mass air flow (MAF) and intake air temperature (IAT) sensor The MAF sensor is located between the air cleaner housing and the air intake hose leading to the throttle housing.
The IAT sensor is incorporated in the housing of the MAF sensor.
The MAF sensor in conjunction with the IAT sensor provides the PCM with the primary load signal.
The PCM uses the signals for the following functions among other things:
  • to control the shift operations,
  • to control the main line pressure.
If the MAF sensor fails, the signal of the TP sensor is used as a substitute.
Crankshaft position (CKP) Sensor The CKP sensor is located on the engine/transmission flange.
The CKP sensor is an inductive sensor which provides the PCM with information about the engine speed and position of the crankshaft.
The signal is used for the following functions among other things:
  • to control the torque converter lock-up clutch,
  • to check the torque converter slip,
  • to control the main line pressure.
No substitute signal is available for the CKP sensor. If the signal is not present, the engine stops.
Turbine shaft speed (TSS) sensor The TSS sensor is located in the transmission housing over the transmission input shaft.
The TSS sensor is an inductive sensor which senses the speed of rotation of the transmission input shaft.
The signal is used for the following functions:
  • to control the shift operations,
  • to control the torque converter clutch,
  • to check the torque converter slip.
If the TSS sensor fails, the signal of the output shaft speed (OSS) sensor is used as a substitute signal.

2000 Accordlx eng. light on and drive blinks yellow code p0780?


po780 is a trans hydrolic systen code
could be a shift solinoid gone bad
have an experienced mechanic replace the lock-up controlle solenoid control solenoid valve/shift controlle solenoid valve "A" assembley
and the A\T clutch pressure control solenoid valve "A"/"B" assembley
start with these two parts farily inexpensive if this doesnt solve the problem then the trans needs to be replaced really expensive
both of these parts are located on the out side of the trans
