SOURCE: Change Automatic Transmission oil

Honda's are drain and refill only.The filter is internal inside the transmission and can only be accessed during an overhaul.On the bottom of the transmission case is a drain plug that is gold in color.It is removed using a 3/8" ratchet,or extension with a ratchet atached.There is also an aluminum washer that must be kept track of and reinstalled with the drain plug or a leak will occur.After draining the trans,and reinstalling the drain plug,Honda genuine automatic transmission fluid,or an equivalent with a highly fricition modified additive must be used,or harsh shifting can occur.I would install about 3 quarts after draining,and start checking the level at this point.The fluid level is checked with the engine OFF,on level ground.

SOURCE: oil leaking on 95 honda accord ex

i would check the oil plug screw seal first before i would do the valve solenoid/pressure switch. also, if the oil plug screw seal is fine and tightly screwed in, it may just be the switch seal itself.

I have the same problem with my 99 accord. For the past few years, I have been able to change out the fuse in the fuse box on the passenger side under the hood of the car up near the windshield. There is a map of the fuses on the top of the box. Hope this helps!

SOURCE: OBD code P0746. Where is the Pressure Control

P0746 Pressure Control Solenoid Performance or Stuck Off
A transmission solenoid is an electro-hydraulic valve that controls fluid flow into and throughout an automatic transmission. Solenoids can be normally open or normally closed. They operate via a voltage or current supplied via the transmission computer or controller. Transmission solenoids are usually installed in a Transmission Valve body, Transmission Control Unit, Transmission Control Module or inside the Transmission and it helps regulate the pressure from the trans fluid pump.


P0446 Evaporative Emmission Control System Vent Control Circuit Malfunction

What does that mean?
Evap vent valve has only one purpose. It closes in order to seal the vent so the EVAP system can pressurize and ensure there are no leaks. Evap vent valve is usually supplied Batt. voltage with key on. The ECM's driver controls the ground, and when grounded, activates the valve (closing it). If the ECM detects a short to ground, and open,or a short to battery voltage on the control circuit, P0446 will set. Code also may refer to ECM detecting that EVAP system is unable to achieve or maintain vacuum during test.

Symptoms
There will be no obvious symptoms to driver, other than MIL illumination.

Causes
A code P0446 could mean one or more of the following has happened:
* Faulty vent valve
* Open, short or excessive resistance on Vent valve control circuit
* Blockage of vent valve
* Bad PCM

Possible Solutions
With a P0446 OBD-II trouble code, here are some things to try:
* Replace Vent valve
* Repair open, short, or resistance problem in control circuit
* Repair open, or short, or resistance problem in power circuit
* Replace PCM


Hope this help (remember rated this post).

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.

Clio auto gear selector the A keeps turning off


possible causes
- low transmission fluid level
- dirty transmission fluid
- faulty line pressure solenoid valve
- line pressure solenoid valve harness is open or shorted
- line pressure solenoid valve circuit poor electrical connection

when the a transmission solenoid is stuck off, in most cases the problem is not the electrical part of the solenoid; the problem is foreign material obstructing the mechanical function of the solenoid or the flow of the fluid through the transmission valve body. if the transmission fluid is very dirty, it is recommend changing the transmission fluid and if possible removing the transmission pan for further diagnosis. excessive debris or metal particles on the transmission pan could be an indication that there is a transmission mechanical failure and that the transmission will need to be rebuilt or replaced.

AUTOMATIC TRANSMISSION GEAR SYSTEM PROBLEM


Yes,that code is a transmission code,pressure control solenoid A.On a Honda trans,there are two solenoids that control line pressure inside the trans.The two of them are made together into one assembly that Honda calls "Linear Solenoids".Most likely they are defective and need replacing,but require testing.They are mounted on the outside of the trans case,so the problem can be repaired without removing the transmission from the car.The actual diagnostic route for that trouble code involves ohms checking the wires from the vehicle computer to the solenoids.Ohms checking the solenoids,amps chekcing the solenoids,and then installing a line pressure gauge on the transmission to test the solenoids mechanically.I rebuild Honda and Acura transmissions on a regular basis,and solenoid failure is not out of the ordinary.Good luck.
