On a 4L60E it is Inside the transmission. Remove the oil pan and it is bolted to the bottom of the front pump, (near the front edge of the pan). Lockup clutch problems are usually not the fault of the solenoid. Failure rate is real low.

It's in the transmission. Remove the trans pan and it is on the solenoid package. But the solenoid may not be the problem. Could be the wiring, plugs(inside and outside the trans), torque converter, or the computer. where is the TCC solenoid located - 7b32d407-41bb-449c-8dd9-0a5f7effbf7f.gif

SOURCE: Where is the Torque Converter clutch solenoid

Actually, the Torque Converter Clutch Solenoid is located within the transmission housing that is easily accessible through the transmission oil pan. The TCC solenoid may vary in location dependent upon manufacture but generally it is located as aforementioned. It can cause your vehicle to stall if stuck open or close because it controls loads to the engine via your torque converter which is located between the vehicle's engine and transmission. Also, make certain that you attempt to change the transmission fluid and filter before changing the TCC solenoid because that may be your underlying issue. If not, simply reuse your fresh oil and change the TCC soleniod.

I have a 2001 aurora and code p1860 p1860 came up what is this and how much to fix


P1860 All GM - TCC (transmission Torque Converter Clutch) PWM Solenoid Circuit Electrical.
P1860 Description The Torque Converter Clutch Pulse Width Modulation (TCC PWM) solenoid valve controls the fluid acting on the converter clutch valve. The converter clutch valve controls the TCC application and release. The solenoid attaches to the control valve body within the transmission. The solenoid receives ignition voltage through circuit 239. The Powertrain Control Module (PCM) controls the solenoid by providing a ground path on circuit 418. Current flows through the solenoid coil according to the duty cycle (percentage of ON and OFF time). The TCC PWM solenoid valve provides a smooth engagement of the torque converter clutch by operating during a duty cycle percent of ON time.
When is the code detected? When the PCM detects a continuous open, short to ground or short to power in the TCC PWM solenoid valve circuit, then DTC P1860 sets. DTC P1860 is a type B DTC.

Possible causes - Faulty Torque Converter Clutch Pulse Width Modulation (TCC PWM) Solenoid
- Torque Converter Clutch Pulse Width Modulation (TCC PWM) Solenoid harness is open or shorted
- Torque Converter Clutch Pulse Width Modulation (TCC PWM) Solenoid circuit poor electrical connection. Unless you have a factory manual and very good auto repair skills this is best left to an expert. It is a messy dirty job that requires removing the parts inside the transmission for testing..

What does the TCC code mean for chevy s10


The Torque Converter Clutch (TCC) solenoid valve is an electrical device that is used with the torque converter clutch pulse width modulation (TCC PWM) solenoid valve in order to control TCC apply and release. The TCC solenoid valve attaches to the transmission case assembly extending into the pump cover. The Powertrain Control Module (PCM) controls the solenoid by providing the ground path. The PCM monitors the throttle position (TP) voltage, the vehicle speed and other inputs in order to determine when to energize the TCC solenoid valve.

replace the relay.....its common for it to go out.

I have a 2004 Chevy Trailblazer and when it gets in high gear it keeps shifting down like it is locking or something. We have had it in shop for 5 weeks and thermostat and coolent sensor have been re


I am afraid you have mis-diagnosed it NOT being the Transmission or I should say Torque Converter, TCC Solenoid. I would strongly recommend that you replace the TCC Solenoid in the 4L60E Transmission. Then see what happens. If you drive it with the TORQUE CONVERTER Button in the OFF Position on the Shifter, does it fix the problem?

P0743 - Torque Converter Clutch Circuit Electrical
Symptoms - Engine Light ON (or Service Engine Soon Warning Light) Possible causes - Faulty torque converter clutch solenoid valve
- Torque converter clutch solenoid valve harness or connectors
- Torque converter clutch solenoid valve circuit is open or shorted
- Low transmission fluid level
- Dirty transmission fluid
Tech notes This is an electrical problem code. Could be a problem to the harness to the TCC solenoid, the TCC solenoid connector or the TCC solenoid it self.

Dashboard message - service engine soon ?? my local service station said it said - torque converter


That is located in the transmission and can be very expensive to repair/replace - Do NOT take to Amco! Did he also tell you the exact electronic code? Uusally, the code will say more than just torque converter.

Have you noticed any hesitation when you are starting to move; in reverse on on a hill - any noticeable slipping?

EOBD Code: P0741
Faiult location: Torque converter clutch (TCC) solenoid - performance or stuck off
Probable cause: Wiring, TCC solenoid

First time check the wires and connection plug & socket of TCC solenoid. If everything will be OK then replace TCC solenoid.

CODE P0741


P0741 "Torque Converter Clutch Solenoid stuck off"
If the PCM detects high torque converter slip when the TCC is commanded ON, then DTC P0741 sets. The Powertrain Control Module (PCM) controls the Torque Converter Clutch Solenoid Valve (TCC Sol. 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.
Thank you for using Fixya and good luck

While in park truck studders and stop running. then starts up again.


u may have a problem with the TCC (Torque Converter clutch) control solenoid, this causes the torque converter clutch to stay locked up and the engine will shudder and stall, I am 99% sure that is the problem.

Error codes


Her is the definition and a list of possiable causes.


Code P1740-Torque converter clutch did not lock up when the PCM sent the command. Enabling conditions: No engine or transmissions codes are present, vehicle speed was under 70 MPH, TPS was under 33% open. When the PCM commanded the torque converter to lock, no change was detected in engine speed. Blocking action: This code can block the following monitors: none.
Testing: Check torque converter solenoid for proper operation.
P1740 TCC O/D SOL PERFORMANCE (GAS)
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
