Toyota 4 runner 2004 model bad solenoids valve 1 and 2 on automatic transmission, engine check light on. Solenoid valves changed still same message.?

P0745 - Pressure Control Solenoid Malfunction 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 Help with this
Tech notes
When the a transmission solenoid is malfunction, 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.
Help with this
When is the code detected?
The P0745 is detected when TCM detects an improper voltage drop when it tries to operate the solenoid valve.
Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Transmission shift shock
P0745 Description
The line pressure solenoid valve regulates the oil pump discharge pressure to suit the driving condition in response to a signal sent from the Transmission Control Module (TCM).

inside the transmission
it is an electromagnetic to hydraulic valve. so needs to be
in the valve body to do the shifts,
all this and more is in the FSM, (shows the tests too)

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.

Possible causes of OBD code P0766
- Low transmission fluid level - Dirty transmission fluid - Faulty shift solenoid D valve - Shift solenoid D valve harness or connectors - Shift solenoid D valve circuit is open or shorted The Error code is generally activated on detection of the following conditions: The P0766 code is detected when the ECM has detected a mechanical fault with the solenoid energized, valve stuck off. I would pull the transmission pan and change the solenoid D valve

P0773 TOYOTA - Shift Solenoid E Electrical Malfunctionhttp://engine-codes.com/p0773_toyota.htmlForum CodePossible causes- Faulty shift solenoid E valve
- Shift solenoid E valve harness or connectors
- Shift solenoid E valve circuit is open or shorted
- Low transmission fluid level
- Dirty transmission fluid

- Low transmission fluid level
- Dirty transmission fluid
- Faulty shift solenoid B valve
- Shift solenoid B valve harness or connectors
- Shift solenoid B valve circuit is open or shorted
these are couple causes to turn on your check engine light

DTC P0755 - Shift solenoid valve B
This warning is turned ON or OFF by the Transmission Control Module (TCM) in response to signals sent from the park/neutral position (PNP) switch, vehicle speed and Engine Control Module (ECM) (throttle opening). Gears will then be shifted to the optimum position.

The P0755 code is detected when TCM detects an improper voltage drop when it tries to operate the solenoid valve.

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- Transmission will not shift gears.

Possible causes:
- Low transmission fluid level
- Dirty transmission fluid
- Faulty shift solenoid B valve
- Shift solenoid B valve harness or connectors
- Shift solenoid B valve circuit is open or shorted

Ok, I am about to solve the mistery on the transmission problems with these 2004 and 2005 Nissan Maxima.
I had 2 Maxima's 2004, let's call car A with a bad transmission and good motor, and car B with good transmission and bad motor.
1. I swap engines from car B to car A, after that, car A runned good with not a single issue.
2. Car B was with out and engine and a bad transmission,
3. I found a motor and transmission from a wrecked salvage 2005 Nissan Maxima with only 25,000 miles in it,
4. After the installation of the good engine and transmission on car B, I found a broken solenoid,
lets call the good engine and transmission (SET).
5. Remember car A is fixed, but car B had a bad transmission.
6. After removing the bad transmission from car B, the SET had a broken transmission solenoid called (pressure control valve solenoid) cause by the accident, the transmission valve cover had a small dent, right where the solenoid is, that how it got broke,
7. Since I still had the bad transmission from car B, the solenoid from that transmission were good in shape, so I thought I was lucky enough to swap the solenoid from car B to the SET,
after I did that I was good to go very confident that car B was going to run fine, but it did not.
8. Car B with a 25,000 miles SET end it up doing the exact same problem that it had before with the transmission, it is near impossible that the problem is the wear on the valve body since the SET only has 25,000 miles and I only swap the solenoid. 2 of them to be exact.
8. Now I am in the market to buy just the 2 brand new solenoids and cross my fingers, Nissan for some reason, they dont want to sell the solenoids by them self, you need to get the complete valve body assy. and shops are happy with that idea cause it is more money on the pocket for dealers and shops, so I hope is the solenoids, they are really easy to replace, just by removing the valve body cover and remove 2 bolts, 1 for each solenoid and that's it. I called one guy who owens a shop and I ask him if he sells the solenoids remanufactured and he started yelling cause he is thinking that we are stupids since he had many people asking about these solenoids and he is saying that the problem is the valve body it self, he make me mad because I only asked him for the solenoids not to try to make me buy the new valve body assy. I will follow up after I find the solenoids and replace these on my Maxima just to confirm, any questions e mail me back at [email protected] thanks
