Question about 2001 Ford Escort ZX2

1 Answer

2001 escort zx2 auto trans shifts immediately upon standing start

Is the shifting controlled by vacumn or electronic? Is there a throttle pressure adjustment? Ford dealer says it needs a new transmission. But, other than this problem, the trans operates quite well. My experience dates back to cars of the 1970's, so I am at a bit of a loss. If shifting is electronically controlled, then it seems to me the problem could be a sensor or even a computer problem perhaps. Is this a problem that will get progressively worse, or should we just put up with it? Thank you.

    Not always, but often, immediately upon acceleration from a standing start, perhaps in the first 10 feet, the auto trans shifts. Thanks for your assistance.

I have a 2007 chevy aveo ls has a vacumn leak sometimes changes gears rough then other times changes just right. cant find vacumn leak. please help.


Most of your vac lines are located close to the throttle body or on top of the motor. The sucking sound you hear when the hood is closed may be the air going through the intake hose and box (smaller cars tend to make more air flow noise than others). If the trans is missing or not shifting properly you may want to look at the neutral safety switch. If your car seems to go and shift fine between 1st and 2nd gear and then it seems like it is guessing then this will be your best bet. You can always install it and if the problem persist then you can take it back, just bee sure to keep your receipt. If it is not that then you may be looking at an internal issue (most newer transmissions are computer controlled and do not use vacuum pressure to shift or downshift like older transmissions).

Let me know if there is any new information or if the fix works.

Electronic pressure control solenoid circuit p1745. Check engine light on 2000 ford escort, 4cl, automatic. Advance auto told me it was a dealer part but I can't find it on any of the ford websites?...


Here is what the service manual says about the EPC solenoid, the processor looks at allot of different inputs to command the solenoids, such as Throttle Position Sensor, Vehicle Speed Sensors, Transmission Range Sensor and RPM signal, The PCM controls the shift patterns for the transmission. Electronic Pressure Control (EPC) Solenoid
The electronic pressure control (EPC) solenoid is located on the main control valve body and is controlled by the PCM. The EPC controls line pressure used to apply and release clutches and bands in the transmission.
The 2-3 shift solenoid is located on the main control valve body and is switched on and off by electrical signals from the PCM. The 2-3 shift solenoid activates the 2-3 shift valve which controls the automatic shifting between second and third gear. Second gear is established when the 2-3 shift solenoid is switched on. The 2-3 shift solenoid is switched off when vehicle speed increases and requires a second to third gear upshift.
The 3-4 shift solenoid is located on the main control valve body and is switched on and off by electrical signals from the PCM. The 3-4 shift solenoid activates the 3-4 shift valve which controls the automatic shifting between third and fourth gear. Third gear is established when the 3-4 solenoid is switched off. The 3-4 shift solenoid is switched on when vehicle speed increases and requires a third to fourth gear upshift.

Why does my 93 olds intrique shift hard


It sounds like you have to much throttle pressure. If your trans. is electronically controlled it could be the speed sensor, if not then check the throttle cable adjustment.

1998 zx2 automatic trans won't shift past 2'nd gear


Governor may be stuck. a solenoid may be stuck open, or stuck closed, or the transmission throttle cable has come undone at one end or the other or has come loose at the ajustment point.

Is the fluid level correct? Is the tranmission fluid correct? (foaming issue) Does the fluid smell burned significantly?

Will it shift if you let up on the accelerator for an instant and then step on it again? If it will shift while doing that, add some seal conditioner as you have a leaking servo seal or clutch apply seal. If that does not correct it after a period of time, the only real fix will be to pull the transmission and do a rebuild.

Hi, I have a 1999 Ford Escort ZX2 with a service engine soon light on and it won't shift into overdrive... Any suggestions? Thanks!!!


I would got to autozone or advance auto parts and have the codes read, they will do it for free, it will give you an idea of where to start looking, could be as simple as just changing a sensor.

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.

96 Ford Contour CD4E Auto Trans.


The item referred to needing adjustment in the previous reply is called the MLP (manual lever position sensor). It tells the computer electronically that the car is in P, R, N, D, 2,1 (depending on the gear selector) It also allows the car to only be started in P and N for safety.
If it is out of adjustment, the sensor is misaligned with it's reference point on the gear selector rod, which goes into the trans case and pushes/pulls a rod that moves the selector piston/valve. The valve will be in the right place but the computer will say other wise and it controls the shifting with the solenoids.
SOURCE INFO:
{MLP transaxle function: determion desired gear and electronic pressure control (EPC) pressure:
Symptoms: Harsh engagements and firm shift feel, engine may not crank, may downshift to a lower gear, 2nd or 3rd gear operation, transaxle not inicating the proper gear, no 4th gear operation. no manual first gear.}
Another point of interest is the EPC (electronic pressure control)solenoid inside the black side cover.
Failed OFF-maximum EPC pressure, harsh engagements and harsh shifts.

Another possible issue may just worn out clutches if the unit has high mileage or maybe verify fluid level and recent change of fluid. The filter is inside unit and trans has to be removed to change, some Hondas are like this too.
