Check engine light code p0755 shift solenoid B fault

Have you check fluid level ? Is your check engine light on ? You have a bad shift solenoid inside the transmission ,more then likely . Have codes checked ,you mite have P0700 + code

P0750 - Shift Solenoid A

P0751 - Shift Solenoid A Performance or Stuck Off

P0752 - Shift Solenoid A Stuck On

P0753 - Shift Solenoid A Electrical

P0754 - 1-2 Shift Solenoid Intermittent

P0755 - Shift Solenoid B

P0756 - Shift Solenoid B Performance or Stuck Off

P0757 - Shift Solenoid B Stuck On

P0758 - Shift Solenoid B Electrical

P0761 - Shift Solenoid C Performance or Stuck Off

According to RepairPal.com: " Common Problems That Trigger the P0755 Code

• Defective Shift Solenoid
• Defective Shift Solenoid wiring or connector
• Defective Valve Body
• Dirty transmission fluid that restricts the hydraulic passages"

P0755 Shift Solenoid B Malfunction
cam not find the P1529 you can call auto zone maybe they can help

This is a fault with auto trans shift solenoid B. It could be low or dirty fluid, the electrical connector, or the solenoid itself. First try draining and refilling the trans fluid, even twice over.

P1782 DODGE - 2/4-OD Pressure Switch Circuithttp://engine-codes.com/p1782_dodge.htmlForum CodePossible causes- Low transmission fluid level
- Dirty transmission fluid
- Faulty 2/4-OD Pressure Switch
- 2/4-OD Pressure switch poor electrical connection
- 2/4-OD Pressure switch circuit is open or shorted
Symptoms- Engine Light ON (or Service Engine Soon Warning Light)
- Transmission shift shockP1782 DODGE Description The pressure 2/4-OD Pressure Switch is part of the pressure switch of the transmission. The pressure switch are located in the solenoid assembly. The switch provide input information to the Transmission Control Module (TCM). The switch will inform to the TCM is pressure exist in a specified hydraulic circuit. the TCM uses this information to verified that the solenoids are working or not.
P0755 DODGE - 2/4 Solenoid Circuithttp://engine-codes.com/p0755_dodge.htmlForum CodePossible causes- Low transmission fluid level
- Dirty transmission fluid
- Faulty 2/4 solenoid valve
- 2/4 solenoid valve harness is open or shorted
- 2/4 solenoid valve circuit poor electrical connection
P0700 DODGE - Transaxle Control System Malfunctionhttp://engine-codes.com/p0700_dodge.htmlForum CodePossible causes- Shorted or open circuit within transmission control module (TCM)
- Failure of transaxle control module Tech notes Since the P0700 is just and informative code, check the TCM for more codes to resolve the problem.
Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Driveability problems
- Transaxle shifting problems

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

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.

Additional test details could find in this link about Repair/05/2011ne09/cip0755 (pdf)

Hope this helps (remember to rate and comment this answer).

inside the trans there are selonoids that control the shifting. they may need to be replaced or you have a wiring problem. another thing you might try having the trans serviced. have the codes cleared and drive the car to see if the codes come back. hope this helps.

P0700 (M)
Check Transmission DTC's
This code indicates that the EATX (Transmission controller) has an active fault and has illuminated the MIL via a BUS message. The specific fault must be acquired from the EATX via a DRBIII tool. (Input or Output Speed Sensor failures often cause this code and are a common failure part on WJ Grand Cherokees

P0750
Shift Solenoid circuit.
Note: If code P1767 (Transmission Relay Always On) is also present: Replace transmission solenoid assembly. See note provided. When transmission is in limp mode the relay that provides power to the solenoid group is switched off. This is normal and is designed to provide operation in one gear only. Engineering department suggests to replace transmission solenoid assembly anytime these two trouble codes occur together. See applicable service manual section (21) for solenoid assembly replacement directions. IMPORTANT: When performing this repair always check torque on all valvebody accumulator cover plate screws. Proper torque specification is 70 inch pounds. If any accumulator cover plate screws are damaged or missing replace the valvebody assembly. NOTE: If any other trouble codes are present do not replace solenoid assembly. See test in the applicable Transmission Diagnostic Procedures Manual

P0755
Shift Solenoid B

Dave, The P0700 code is a generic fault code indicating the the TCM (transmission control module) has recognized a problem and the P0755 is the indicated problem. I'd recommend you check your transmission external electrical connector for water intrusion and corrosion at the terminals by disconnecting the connector. If nothing appears wrong, I'd then recommend you drop the lower transmission pan and take a look at the residue deposit that is laying on the bottom of the pan. You should only see a relativily minor amount of grayish, black clutch material residing there. Pay particular attention for a gross amount of this or any large particular material, including any metal, either filings or chunks, or any brass or aluminum. If this checks out to be fairly clean, then I'd recommend you replace that "B" solenoid (2-3 shift solenoid) and have the trans. pan and filter replaced.; I'd also highly recommend you have the trans flushed for anyother particular matter that may reside internally inside the transmission. You'll have to have the codes cleared and the transmission relearned for shift feel, at that point.
