SOURCE: 2002 Sunfire TCC Solenoid replacement

hi..the transaxle converter clutch . tcc. uses a solenoid -operated valve located in the automatic transaxle to mechanically couple the engine flywheel to the output shaft of the transmission through the torque converter.that reduces the slippage loss in the converter.reducing emissions.but check the vss first.which is called the vehicle speed sensor.they both work together .if the vss is not working right it wont call on the tcc.
check this out..
thank u..
rate me..

SOURCE: p1744 enginge code tcc solenoid circuit

DTC P1744 is "TCC - Excessive Slip Detected During Full TCC Engagement". Which means that the Torque Converter Clutch (TCC) is disengaged or the EPC pressure is at the minimum.

The most likely cause is a sticking or bad TCC solenoid inside the transmission. You can check the connector at the transmission to make sure it is clean and tight and that it is not damaged in any way.

If the TCC and wiring is okay, then pressure testing of the transmission will need to be done.

A new torque converter from Ford is about $265.00 and about 4 hours labor. Throw in a $40.00 TCC solenoid and I don't think it'll be more than $700.00 at worst.

If the pressure test is good then it's just going to be the $40.00 tcc solenoid and the cost of the transmission oil and filter changed which should be around $150.00

Good luck and hope it's just a loose wire harness to the solenoid which would cost $0.00 and just your time to locate the break in the wire. The other thing to, is to add a transmission fluid additive that would restore the clutch pack in the transmission and Torque Converter.

SOURCE: THE AW60-40LE TRANSMISSION DOES NOT HOLD TCC

The MAF is almost certainly not the issue, as it would tend to generate other codes and more severe drivability problems. If the rebuild did not include replacement of the TCC solenoid, then it may need to be replaced. It can be tested by applying battery voltage to one lead momentarily, while the other side is grounded. If the connector is a single lead, clip a ground to any metal part of the body of the solenoid, or leave it installed when testing, if possible. If it is a double lead, reverse polarity once when testing. If the solenoid does not click or move, regardless of polarity, it is bad. You can also test the resistance across the solenoid. Use a known-good unit to determine appropriate resistance. Your dealer may be willing/able to tell you the appropriate value. If the unit being tested is very low or much higher resistance compared to the reference unit, or if the meter shows no connection, it is a bad solenoid. The test unit resistance should be within about 10% of the value of the reference unit.

SOURCE: vehicle will not shift into overdrive after it

"The PCM controls the torque converter clutch (TCC) solenoid valve pulse width modulation (PWM). The solenoid controls the hydraulic fluid for TCC apply and release. When the TCC is applied, the engine is coupled directly to the transmission through the TCC. The TCC slip speed should be near 0.

If the PCM detects high torque converter slip when the TCC is commanded ON, then DTC P0741 sets. DTC P0741 is a type B DTC.

Conditions for Running the DTC
• No TP DTCs P0121, P0122 or P0123.

• No VSS DTCs P0502 or P0503.

• No AT ISS DTCs P0716 or P0717.

• No TCC stuck ON DTC P0742.

• No IMS DTCs P1820, P1822, P1823 or P1825.

No TCC PWM solenoid valve DTC P1860.

• The engine run time is greater than 5 seconds.

• The time since the gear select lever change is greater than 6 seconds.

• The IMS indicates D2, D3 or D4.

• The transmission gear ratio indicates 2nd, 3rd or 4th gear.

• The transmission fluid temperature is 20-133°C (68-271°F).

• The TP angle is 10-50 percent.

• The engine torque is 43-215 N·m (32-159 lb ft).

• The TCC solenoid valve is commanded ON.

Conditions for Setting the DTC
TCC slip speed exceeds its limit for a given torque for 5 seconds.

Refer to Torque Converter Clutch Slip Speed .

Action Taken When the DTC Sets
• The PCM illuminates the malfunction indicator lamp (MIL) during the second consecutive trip in which the Conditions for Setting the DTC are met.

• The PCM inhibits 4th gear if the transmission is in hot mode.

• The PCM records the operating conditions when the Conditions for Setting the DTC are met. The PCM stores this information as Freeze Frame and Failure Records.

• The PCM stores DTC P0741 in PCM history during the second consecutive trip in which the Conditions for Setting the DTC are met.

Conditions for Clearing the MIL/DTC
• The PCM turns OFF the MIL during the third consecutive trip in which the diagnostic test runs and passes.

• A scan tool can clear the MIL/DTC.

• The PCM clears the DTC from PCM history if the vehicle completes 40 warm-up cycles without an emission-related diagnostic fault occurring.

• The PCM cancels the DTC default actions when the ignition switch is OFF long enough in order to power down the PCM.

Engine code 894


DTC P0894 Transmission Component Slipping
DTC P0894Circuit Description with 4L80-E / 4L85-E Automatic Transmission The powertrain control module monitors the engine speed and the transmission output shaft speed. The PCM calculates turbine shaft speed and torque converter clutch (TCC) slip speed by using inputs from the automatic transmission input shaft speed sensor, automatic transmission output shaft speed sensor, and other transmission components. The forward clutch housing is used as the AT ISS rotor. Whenever the TCC is engaged, engine speed and turbine speed will closely match, indicating low TCC slip speed. In D3, with the TCC engaged, calculated transmission component slip can only occur in the torque converter. In D4 OVERDRIVE, with the TCC engaged, transmission component slip can occur in the TCC or the fourth clutch assembly. If the PCM detects an excessive TCC slip speed in D4 OVERDRIVE, when the TCC should be engaged, then DTC P0894 sets. DTC P0894 is a type C DTC. For California emissions vehicles, DTC P0894 is a type B DTC.DTC Descriptor This diagnostic procedure supports the following DTC: DTC No MAF sensor DTC P0101, P0102 or P0103. No MAP sensor DTC P0106, P0107 or P0108. No TP sensor DTC P0120 or P0220. No VSS DTC P0502 or P0503. No ISS DTC P0716 or P0717. No TCC Stuck Off DTC P0741. No TCC Stuck On DTC P0742. No 1-2 SS valve DTC P0751, P0752 or P0753. No 2-3 SS valve DTC P0756, P0757 or P0758. No TFP manual valve position switch DTC P1810. No TCC PWM solenoid valve DTC P2761. The throttle angle is 10-100 percent. Engine speed is 1,250-5,000 RPM. The TFT is Vehicle speed is TFP manual valve position switch indicates D4. The TCC is commanded ON for 0.04 second or greater. TCC is locked ON for greater than 0.1 second. Commanded The PCM detects slip in the torque converter clutch and/or the fourth gear clutch pack with the TCC in an apply or locked mode. DTC P0894 sets during the second consecutive trip when one of the following conditions occur: The TCC slip speed is 100-550 for 10 seconds for three occurrences.The TCC slip speed is 100-550 for 10 seconds, the PCM commands maximum line pressure. The TCC slip speed is 100-550 for 12.5 seconds, the PCM commands the TCC Off for 2 seconds. The TCC slip speed is 100-550 for 15 sec For California emission equipped vehicles, the PCM illuminates the malfunction indicator lamp during the second consecutive trip in which the Conditions for Setting the DTC are met. For Federal emission equipped vehicles, the MIL is not illuminated. The PCM commands maximum line pressure. The PCM inhibits the TCC engagement. The PCM freezes transmission adaptive functions. The PCM records the operating conditions when the Conditions for Setting the DTC are met. The PCM stores this information as Freeze Frame, California only, and Failure Records, California and Federal. The PCM stores the DTC P0894 in PCM history during the second consecutive trip, California, or the first trip, Federal, in which the Conditions for Setting the DTC are met. For California emissions, the PCM turns OFF the MIL during the third consecutive trip in which the diagnostic test runs and passes. A scan tool can clear the MIL/DTC. For California emissions, the PCM clears the DTC from PCM history if the vehicle completes 40 warm-up cycles without an emission related diagnostic fault occurring. For Federal emissions, the PCM clears the DTC from PCM history if the vehicle completes 40 warm-up cycles without a non-emission related diagnostic fault occurring. The PCM cancels the DTC default actions when the fault no longer exists and the ignition switch is OFF long enough in order to power down the PCM. A TFP manual valve position switch malfunction can set DTC P0894. A mechanical failure of the shift solenoids or TCC PWM solenoid valve can set DTC P0894. Internal transmission failures can result in a DTC P0894. Sticking or contaminated shift valves may cause intermittent slipping in D4. DTC P0894 defaults to an elevated line pressure condition which may result in partial TCC apply. This may produce an idle surge that could stall the engine. The numbers below refer to the step numbers on the diagnostic table. 3. This step tests the indicated range signal to the actual selected range. A faulty TFP manual valve position switch can set a DTC P0894. 4. This step tests for excessive TCC slip speed while in a commanded TCC lock-up state and in fourth gear; and confirms that the fault is present. 5. This step tests for excessive TCC slip speed while in a commanded TCC lock-up state and in third gear. 6. This step tests for a sticking TCC shift valve. 7. This step tests for proper transmission line pressure.

The TCC solenoid is located inside the transmission. Replacing the solenoid usually does not fix the problem when it comes to a P0741 code. It is usually due to debris getting caught in the TCC regulator valve or the tubine shaft seals being worn out. This usually results in a transmission overhaul.

Theory of Operation
The Torque Converter Clutch (TCC) Solenoid is used to engage the TCC which improves fuel economy.
When Monitored
The Torque Convertor Clutch (TCC) and Overdrive Clutch (OD) will be tested each time the PCM requests TCC engagement in 3rd gear and OD.
Set Condition
The DTC will set if the expected RPM drop is not achieved while attempting to engage TCC or OD. This indicates a malfunctioning torque convertor or overdrive clutch.
Possible Causes
* ENGINE DTCS PRESENT
* TRANSMISSION DTCS PRESENT
* TRANSMISSION TEMPERATURE TOO COLD
* OIL PAN CONTAINS EXCESSIVE DEBRIS
* 3-4 SHIFT SOLENOID
* SHAFT OR SEAL DAMAGE
* TCC SOLENOID
* TORQUE CONVERTER
