the p0750 is a shift solenoid A malfunton,whice in turn will set the p0700 code,if you change the shift solenoid that should get rid of both codes.

It's an exhaust valve inside the transmission, when the solenoid isn't working right, the pressurized fluid can't exhaust through the passages, which can cause rough shifting. It has to be taken to a transmission shop, the transmission pan has to be dropped and possibly the valve body to get at the solenoid. Hope this helped.

SOURCE: p1744 enginge code tcc solenoid circuit

DTC P1744 is "TCC - Excessive Slip Detected During Full TCC Engagement". Which means that the Torque Converter Clutch (TCC) is disengaged or the EPC pressure is at the minimum.

The most likely cause is a sticking or bad TCC solenoid inside the transmission. You can check the connector at the transmission to make sure it is clean and tight and that it is not damaged in any way.

If the TCC and wiring is okay, then pressure testing of the transmission will need to be done.

A new torque converter from Ford is about $265.00 and about 4 hours labor. Throw in a $40.00 TCC solenoid and I don't think it'll be more than $700.00 at worst.

If the pressure test is good then it's just going to be the $40.00 tcc solenoid and the cost of the transmission oil and filter changed which should be around $150.00

Good luck and hope it's just a loose wire harness to the solenoid which would cost $0.00 and just your time to locate the break in the wire. The other thing to, is to add a transmission fluid additive that would restore the clutch pack in the transmission and Torque Converter.

SOURCE: I HAVE CODE P0075 P0026

Hi

the most likely cause of this code is the MAF sensor or air mass sensor "same thing" this regulates the air to fuel mixture, worth a mention you can try and clean this sensor with carb cleaner and this often cures the fault.

1999 blazer code po785 ?


When the Powertrain Control Module (PCM) detects a continuous open, short to ground or short to power in the 3-2 SS valve assembly circuit, then DTC P0785 sets.

Possible cause are
- Low transmission fluid level
- Dirty transmission fluid
- Faulty shifting solenoid valve
- Shifting solenoid valve harness is open or shorted
- Shifting solenoid valve circuit poor electrical connection

2-3 shift solenoid circuit


P0758 Chevrolet P0758 Chevrolet - 2-3 Shift Solenoid Circuit Electrical
Possible causes
- Low transmission fluid level
- Dirty transmission fluid
- Faulty 2-3 Shift Solenoid Valve
- 2-3 Shift Solenoid Valve harness or connectors
- 2-3 Shift Solenoid Valve circuit is open or shorted
What does this mean? When is the code detected?
When the Powertrain Control Module (PCM) detects a continuous open, short to ground or short to power in the 2-3 Shift Solenoid (SS) valve circuit, then DTC P0758 sets.
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Transmission will not shift gears
P0758 Chevrolet Description
The 2-3 Shift Solenoid (SS) valve controls the fluid flow acting on the 2-3 shift valves. The 2-3 SS valve is a normally-open exhaust valve that is used with the 1-2 SS valve in order to allow four different shifting combinations. The solenoid attaches to the control valve body within the transmission. The Powertrain Control Module (PCM) controls the solenoid by providing the ground path.

2005 nissan frontier problem code 1757 and 1759


ObdII Code 1757 means the transmission oil could be burned or the oil pan has excessive dirt in it. There could be internal transmission damage. However, other things that throw that code include a faulty Governor Pressure Sensor, a Faulty Governor Pressure Solenoid, a Faulty Valve Body, an engine Control Module (ECM) 5 volt supply, a 5 volt supply circuit could be open, a 5 volt supply circuit could be open inside the transmission, or a - Faulty Engine Control Module (ECM).

On the other hand, a Code 1759 means a possible faulty Front Brake Solenoid Valve, or a front Brake Solenoid Valve harness is open or shorted, or a Front Brake Solenoid Valve circuit with a poor electrical connection.

What kind of trouble code is this and how i want to solve it.. help me!!


Hi, these are taken from the data sheets

P1523 - electronic throttle system (ETS) - throttle valve sticking - probable cause = mechanical fault, ECM

P0204 - injector 4 - circuit malfunction - probable cause = wiring, injector, ECM

P0206 - injector 6 - circuit malfunction - probable cause = wiring, injector, ECM

hope that helps

It also has code po743 and po755


P0743 - Torque Converter Clutch Circuit Electrical
Possible causes- Faulty torque converter clutch solenoid valve
- Torque converter clutch solenoid valve harness or connectors
- Torque converter clutch solenoid valve circuit is open or shorted
- Low transmission fluid level
- Dirty transmission fluid
Tech notes This is an electrical problem code. Could be a problem to the harness to the TCC solenoid, the TCC solenoid connector or the TCC solenoid it self.
P0755 - Shift Solenoid B Malfunction
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 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.

Check engine light came on


What do you mean "can't find code"? If the check engine light is on, there is a fault code stored in your onboard computer - that's the way it works. If you are using a generic OBD code reader, that is most likely the reason you cannot find any codes. You need to use a scanner that has the correct software to access your ENTIRE computer network, not just the "continuous memory" or "generic" side of your computer system.

The window problem is a seperate problem and must be diagnosed accordingly.

I have a 2001 lincoln contintental the code that pops up is 1744, can somone tell me what that is and how to fix it?


P1774 - Link Gear Shift Module / TCM

This means the computer has detected a slippiage. First thing you can do is a transmission pressure test, it should be 62-81 psi while in park or drive and 110-120psi while in revese. If pressure is low the problem could be the pump, a external or internal leak, pressure regulator valve, or epc soenoid/circuit. Otherwise you could start by replacing the EPC solenoid and the pressure regulator valve. If that does not fix the problem you would probably want to bring the vehicle into a transmission shop to have them diagnose the problem.

The EPC solednoid is the most common cause of this from what I'm aware but the torque converter itself could be the problem also but you would want to have every other possible cause checked before replacing the converter since that is expensive and time consuming.

Hope this helps (remember to rate this).
