Ford focus 2005 2.0l auto i bought solenoid a, b and d. Autozone showed d nothing changed. Problem was shifting from 2 to 3. Had to help it shift. Changed d solenoid then nothing changed. E light on

no problem told at all, what caused you to act (DIY)
TELL WHERE THIS SOLENOID RESIDES
WE CAN'T SEE YOU HANDS
YOU WENT
INSIDE THE TRANSMISSION. DRAINED ATF , DROPPED PAN/
AND SAW 6 SOLENOIDS THERE?>
OR IS IT THE PARK LOCKOUT SOLENOID, under shift console

as in shifter stuck in park?

7 SOLENOIDS BY COUNT JUST FOR SHIFTING

if the vehicle is performing as intended , then use a scan tool to reset the ECM unit.

Don't know the make , model an year vehicle you have but there all pretty much in the same place ! Here he is changing shift solenoid A , he shows b solenoid ! The pan on the bottom of the transmission has to come off . Drain trans fluid ! Ford Focus Shift Solenoid Repair P0750 P0753 P0972

shift solenoid in transmission

IT DOESN'T SAY THE SOLENOID IS BAD, JUST THAT IT HAS A PROBLEM IN THE CIRCUIT TO THE SOLENOID, THIS CAN BE WIRING OR THE SOLENOID THAT IS AT ISSUE. THE SOLENOID IS PART OF A PACK OF SHIFT SOLENOIDS AND IT IS LOCATED INSIDE THE TRANSMISSION, YOU MUST REMOVE THE PAN FROM THE TRANSMISSION AND IT IS ATTACHED TO THE VALVE BODY. THIS IS A VERY MESSY JOB BECAUSE THERE IS NO FLUID DRAIN PLUG.

The code is for shift solenoid, this can include the fuse and relay which should be in the power distribution block under the hood. it may also be debris in one of the passages behind one of the solenoids. There may also be a ruptured/damaged seal to the overdrive clutch pack as well. Road test with pressure gauge and see what the pressure does at each shift point.

i have hard time shifting from 1st gear to 2nd gear please help me

Sounds like you need to cover basics first. The battery cables are clean and tight? Are all the wires in the battery cable at the battery making a good connection? Sounds like a common problem and is in the service bullitins is that the ground wire attached to the battery cable end that goes to the body and then to the transmission case bolt has failed to provide a good ground and the acuators and servos and even the switches have'nt a good path to ground ( their is one but it's though other controllers and the power isn't strongly grounded. I f you were following a dianostic tree of good and bad the ground is the number one cause of your problem. Don't fix the old grounds just add new ones. and then clear codes and test it again. Oil leaks near the transmission to engine connection were found by me everytime that I was assigned to this set of problems. Ground corrected and the car was fixed.

SHIFT solenoid

your trans has lectronic controls to operate the shifting of your trans. If there is a defect, a fault code will be stored in the computer, called a DTC. You need to have someone with a scan tool check for the fault code. It is likely a solenoid that is not working or stuck.

Get the codes first. Autozone can run the test for free on engines, maybe trans codes too. Call your local Autozone or big parts store and ask them.

SECTION 307-01: Automatic Transaxle/Transmission 2001 Escape Workshop Manual
DESCRIPTION AND OPERATION Transaxle Description The CD4E automatic transaxle is a four-speed, front wheel drive automatic transaxle with electronic controls for:

• Electronic pressure control (EPC) solenoid for shift quality.
• Shift scheduling.
• 3-2 shift timing.
• Coast braking.
• Torque converter clutch control.

The transaxle features a four element torque converter with a torque clutch and a geartrain that includes:

• Compound planetary gearset.
• Chain drive.
• Planetary gearset final drive.
• Pinion and side gear differential.

The hydraulic control system of the transaxle has five solenoids that control:

• Shift feel, through line pressure control.
• Shift scheduling, through shift valve positioning control.
• Modulated application of the torque converter clutch.
• Timing of 3-2 shifts.
• Engine braking during coast operation.

----------------------------
Solenoid Valve Body Assembly The solenoid valve body assembly contains the transmission fluid temperature sensor (TFT) sensor, as well as five PCM controlled output devices:

• Electronic pressure control (EPC) solenoid.
• Shift solenoid A (SSA).
• Shift solenoid B (SSB).
• 3-2 timing/coast clutch solenoid (3-2 T/CCS).
• Torque converter clutch (TCC) solenoid.

---------------------------------
You may need your PCM, Powertrain Control Module reflashed by a Ford Dealer.
Try disconnecting your battery for 1/2 hour and then reconnect and see what happens. It will run a little rough and shfit hard until it relearns your engine/trans characteristics.
Let us know results of tests and DTC codes if you get them.
