P0745 Pressure control solenoid malfunction.

I took my car to the dealership and they have 2 options for the fix...

1. Is it worth it to just replace the solenoid itself. For $700

2. Or should I go for the tranny replacement as suggested by the dealership (as they said trans fluid seems to be burned)for $2700.

Any thoughts on this will be very much appreciated.

Thats a gamble. Whats the car worth? Maybe you are better off trading it in? 2700 is a lot of money for a trans on a 8 year old car. You can always go to a trans shop and get a second opinion, which I would do.

How many miles on the car?trans?
High miles =complete trans change.
Low miles= just the solenoid.

Did you check for a low mileage used trans?
All cars run on used parts.
Also a independent trans shop may do the job for less.
I would estimate....change pressure solenoid and fluid/filter change...about $400

    I Have A 2004 Mazda 6 With A 2.3L Same Code - The Pressure Control Solenoid Has High Reistance 13.1 ohms Specification Calls For 2.4 ohms. - Now You Can Replace The Solenoid Or The Valve Body Or The Transmission. It Takes M5 ATF. If You Change The Solenoid, It Takes About 6 Hours, So It Would Be Over $700.00 To Fix

I got a OBD car fault code po745.,on my Renault methane senic 2003., 106k ml.,what does it means?

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).

Error Code P0745
  • If the error code checker returns a P0745 code, it is indicative of a transmission issue. Error codes in the 700s refer to transmission problems. The P0745 error code refers specifically to a malfunctioning pressure control solenoid. This should be checked by a mechanic as soon as possible.

    ...my 2002 ford expl. showing

    Replace your Pressure Control Solenoid, or take it to a shop and have them replace it. This can cause both of the codes you are experiencing.

    It is not either simple or cheap.

    You will need a mechanic with knowledge of that tranny or a ntransmission shop to do the repairs.
