Replace the Torque Converter Solenoid in
the transaxle

What you have is like coming to a stop with
a manual shift & not pushing in the clutch & it stalls
the motor

The converter clutch is staying locked & your
trans is connected to the motor

SOURCE: Trans shifts very hard after 5 minutes of stop and go traffic

A reason for hard shifting could be a problem with many things with various degrees of seriousness. It could be your ATF( automatic transmission fluid) is low or broken down and old. This would cause the hardness and the reason for stop and go traffic effecting it. Another possibility is your transmission is just shot, and the timing gears inside are worn and not properly shifting at the correct RPM causing a **** during shifting.

Some possibilties, not all!

SOURCE: continous surging and stalling

Per your description, I would suspect a fuel pump issue. When the fuel pump is running the pump impeller heats up. On an older pump the impeller can begin to seize up and momentarily stops and starts. Some times it just stops and has to cool down for a couple of minutes, then is ok for a while.
To test this theory, when the engine stalls and stops, your mechanic can use a rubber mallet and hit the bottom of the gas tank, this will free the pump impeller and the car will start again.
Or, have him install a fuel pressure gauge and go for a drive. If the pressure begins to fluctuate and drop, you know the pump is causing the issue.
Good luck, let me know.

SOURCE: VERY HARD SHIFTS AFTER ENGINE IS WARM.

Your going to have to get the car scanned for the DTC code. The Check engine light indicates that the ECM has detected an issue with the cars engine or transmission performance. Your hard shifting could be the failure to the Pressure control solenoid (PCS), that would be a DTC code P1811. The PCS is located under the trans axle side cover assembly. IF you go to Auto Zone, they can scan your car free of charge and can give you the step by step instruction to replacing the part that may have failed. Good luck and keep me posted, be glad to help.

Need new clutchplate & pressure plate for manua

Instructions
  1. Remove the Old Clutch
    • 1Verify that your vehicle's clutch is the source of your problems and not the pedal-arm bushings, activating cables or the slave-master cylinder.
    • 2Unhook the positive battery cable, the clutch cable or hydraulic slave cylinder to get the transaxle ready for easy removal. Eliminate anything that may hinder your efforts, including exhaust pipes and the speedometer.
    • 3
    • Secure your car in a safe position before jacking up the front end.
    • 4Stabilize the engine with a jack below the oil pan. Remove the transaxle by undoing at least one engine mount.
    • 5Separate the engine from the transaxle by removing the bolts that surround the flywheel bell housing.
    • 6Push the transaxle away from the engine until the input shift clears the pressure plate.
    • 7Disengage the bolts surrounding the pressure plate and take it and the clutch disc out. Check to see if the flywheel's friction surface is scored, checked or has hot spots. Remove, machine and reinstall the flywheel, if needed.
    • 8Examine the pilot bearing (bushing) located at the flywheel's center to be sure the needle bearings are lubricated and that there's no galling. Also look for any oil leaking around the rear main engine seal.
    Replace the Clutch
    • 9Follow the instructions for replacing your car's clutch carefully to avoid having to remove the transaxle.
    • 10Check that the transaxle's input shaft isn't leaking; replace if needed.
    • 11Take out the flywheel and the old seal and install a new seal.
    Install a New Clutch
    • 12Clean the crankshaft flange before putting in the flywheel. With the flywheel on top of the flange, secure the bolts in a star formation to the specified torque for your vehicle.
    • 13Install the clutch disc and pressure plate. Prior to putting in the transaxle, attach the new release bearing to the release fork. The fork should move freely.
    • 14Hoist the transaxle into position and move it forward until the input shaft glides into the clutch disc's spindled hole. Do not apply force.
    • 15Reinstall any bolts or mounts that were removed to replace your car's clutch. Grab the transaxle, release the jack and lower your vehicle.
    • 16Consider replacing your car's clutch cable. If you don't replace the cable at least adjust it for the right amount of free-play.
    • 17Confirm that your clutch's self-adjusting action is performing correctly by depressing the slave cylinder's piston into its bore.
    • 18Drive your car to be sure your clutch is working properly.

When slowing down, everything is fine, until its almost time to fully stop, then the car acts like it is going to die. if I put the car in nuetral, then stop, its fine, it only does this in drive and at a...

Are there codes in the transmission computer? Likely the torque converter clutch is not disengaging or a holding member with the transmission could not be releasing. this could be caused by a faulty shift solenoid or a mechanical failure with the transmission. Check to ensure the transmission shift properly under all conditions. Also, stall test the torque converter, put it in gear hold the brakes firm and throttle the engine. Generally the torque converter will stall out around or above 2,000 rpm. If it stalls out much lower, check the torque converter clutch solenoid for proper operation.

Again, check the transmission computer for codes. You will need an advanced OBD1 scan tool which can communicate like a hikock scan tool ( ford factory for that era)

Tourque converter not locking up

DESCRIPTION:
The torque converter clutch (TCC) inside the torque converter, also referred to as the "damper clutch" or "lockup clutch", functions to lock the input and output sections of the torque converter together to provide improved fuel economy.
If you are servicing a transaxle with either of the following conditions, follow the repair procedure shown below:
^ Torque converter clutch does not engage when driving at steady speed on the highway. ^ Engine stalls when coming to a stop or when shifting into Drive or Reverse

REPAIR PROCEDURE:
1. Check the ATF level when the engine is idling in "N" according to TSB 01-40-013. Adjust the ATF level as needed.


dak408_17.gif
. Attach the Hi-Scan Pro and check for Diagnostic Trouble Codes (DTC) in both the "ENGINE" and "AUTOMATIC TRANSAXLE" menus. If the DTC shown are found, follow the repair procedure shown. If no DTC are found, go to Step 3.
3. Using the Hi-Scan Pro, select "HYUNDAI VEHICLE DIAGNOSIS", "AUTOMATIC TRANSAXLE" and "CURRENT DATA" menus, then "OIL TEMPERATURE" or "FLUID TEMPERATURE". Confirm the oil temperature readout is correct as shown. If not, replace the oil temperature sensor.dak408_10.jpg
4. Using the Hi-Scan Pro, select: ^ "HYUNDAI VEHICLE DIAGNOSIS" menu ^ "AUTOMATIC TRANSAXLE" menu ^ "CURRENT DATA" menu ^ THROTTLE P. SENSOR, "TCC SOLENOID DUTY", "TCC SLIP" and "OIL TEMPERATURE" ^ F2 - "SCRN". This will isolate the top four data to allow a quicker refresh rate for the data. dak408_18.gif
Check the TCC data under the conditions shown in the table. If the TCC data indicate as shown, the torque converter and damper clutch are operating correctly. If not, go to Step 5.

dak408_19.gif
5. If the TCC data does not indicate as shown or the engine stalls, follow the repair procedure shown.
dak408_11.jpg
6. If the engine stalls when shifting into Reverse or Drive, the oil cooler may be restricted. Disconnect the oil cooler hoses to the oil cooler in the radiator. Bypass the oil cooler as shown. It the condition: ^ Does not recur, replace the radiatorRecommend finding a certified Transmission mechanic if you are unable to complete these test using a scanner.

2001 ESPACE 2.0L AUTO NO REVERSE HELP PLEASE

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.
