If there is a torx plug in the middle of your transmission drain plug, you put the car level on stands, start the engine, remove that torx plug, insert a small hose up into the trans, and squirt fluid into the hose until it starts coming back out. Then remove the hose, replace the torx plug, and kill the engine.

P0745 Ford Pressure Control Solenoid Malfunction Your best bet is to take your vehicle to AAMCO

P1491 Rad Fan Control Relay Circuit An open or shorted condition detected in the radiator fan control relay control circuit. This includes PWM solid state relays.P1495 Leak Detection Pump Solenoid Circuit An open or shorted condition detected in the Leak Detection Pump (LDP) solenoid circuit.P0753 (M) Trans 3-4 Shift Sol/Trans Relay Circuits An open or shorted condition detected in the overdrive solenoid control circuit or Trans Relay Circuit in JTEC RE transmissions. Was MIL code 45. P0753 (M) Trans 3-4 Shift Sol/Trans Relay Circuits An open or shorted condition detected in the transmission 2-4 shift solenoid circuit (4-speed auto. trans. only).P0136 (M) 1/2 O2 Sensor Heater Circuit Malfunction Oxygen sensor heater element malfunction.

Aside from getting into an accident and having your wiring harness severely damaged, the other likely suspect is your PCM. These codes are not related to each other and indicate a much larger problem.

Hi.............P0748 being a pressure control solinoid ,elecrical, to me a means that there is an electical problem in the solinoid circuit or the solinoid it self maybe burnt out. The pressure control solinoid is in the trans.On chrysler the solinoids are duty-cycle and controlled by the P.C.M. power train control module which is the same as E.C.M. . A test has to be performed to determine the problem. .

Symptom:

P-0748 GOV PRESSURE SOL CONTROL/TRANS RELAY CIRCUITS

When Monitored and Set Condition:

P-0748 GOV PRESSURE SOL CONTROL/TRANS RELAY CIRCUITS

When Monitored: Continuously with the key on.

Set Condition: This code is set if the voltage detected on the Governor Pressure Solenoid

Control Circuit at the PCM is different than the expected voltage for 4.8 seconds.

POSSIBLE CAUSES

NO POSSIBLE CAUSES REMAINING

FUSED B(+) CIRCUIT OPEN

SOLENOID AND HARNESS ASSEMBLY DEFECTIVE

GOVERNOR PRESSURE SOLENOID DEFECTIVE

TRANSMISSION CONTROL RELAY DEFECTIVE

GOV PRESSURE SOLENOID CONTROL CKT SHORT TO GROUND

GOVERNOR PRESSURE SOLENOID CONTROL CIRCUIT OPEN

GOVERNOR PRESSURE SOLENOID WIRING HARNESS OBSERVABLE DEFECT

TRANSMISSION RELAY OUTPUT CIRCUIT OPEN

TRANSMISSION RELAY OUTPUT CIRCUIT SHORTED TO GROUND

PCM DEFECTIVE (GOV PRESSURE SOLENOID SHORT TO VOLTAGE)

PCM DEFECTIVE (RES IN RANGE)

PCM DEFECTIVE (CONTROL CIRCUIT SHORTED)
PCM DEFECTIVE (SOLENOID & HARNESS ASSEMBLY DEFECTIVE)

P0411 means there is no flow during test. either the vacume hose to purge solinoid is leaking or the vent valve is stuck closed. More than likly a faulty vacume tocontrol sol. in engine compartment, black hose with green cap on itis from tank folow it to purge control sol,and check the rest of its hoses. good luck!

When is ASC button - press to off traction , end warning control of traction lighting.
When is DSC button - pres and hold 5seconds. warning control of traction lighting.

replace the solenoid & flush the trans fluid & replace with fresh/new fluid.

It is in the bottom pan. In order to replace it you have to replace all the solenoids. They are all built into a solenoid pack. What does it do when it shifts to 2nd? Not at all or slips?
