Maybe. Someone would need to check the circuit and the torque converter solenoid to see what the problem is.
There is a possibility the torque converter is faulty, but usually its the solenoid or the wiring harness from the computer.

Changing trans fluid only gives you

disapates heat better with new fluid

The codes are for torque converter clutch,so why not
diagnose the TCC Solenoid

My check engine on and code p0741 is coming up and dealer says i need a whole new transmission.


DTC P0741 TORQUE CONVERTER CLUTCH SOLENOID PERFORMANCE (SHIFT SOLENOID VALVE SL)

There are several possible causes for this code. Yes, it COULD be that there is damage inside the transmission that will require transmission removal and overhaul. However, I have fixed this code a number of times by simply replacing the shift SL solenoid which is mounted externally on the transmission housing.

I would recommend taking your car to a shop that specializes in transmission repair and get a second opinion.

P0741 is internal transmission failure the clutches fail along with the torque converter and the transmission will need to be replaced.

Check and follow this procedure from Honda Service News November 2003 TITLE:
A/T DTC P0740, P0741 Repair Tips: Another Look APPLIES TO: All Models

SERVICE TIP: If you're doing a repair for DTC P0740 or P0741 (lock-up control system) on any Honda models with A/T, except Passport, refer to this table first:

zjlimited_455.gif

If there is no S/B posted on ISIS for the vehicle you're working on, go to the DTC P0740 or P0741 troubleshooting procedure in the Automatic Transmission section of the appropriate S/M or under DTC Troubleshooting in ISIS. If the procedure recommends replacing the A/T, make sure you have a reman A/T on hand. Remove the original A/T, and look at the condition of the torque converter O-ring. Then follow these tips to ensure a lasting repair.

Missing or cut O-ring . If the O-ring is missing or cut, the ATF can leak internally, causing DTC P0740 or P0741 to set. Replace the O-ring, and reuse the original A/T. Make sure the problem has been fixed by connecting the HDS and testdriving the vehicle using the previous DTC P0740 or P0741 freeze data parameters (match the TPS and VSS values for at least 25 seconds ). If the DTC comes back, install the reman A/T. If the DTC doesn't come back, return the reman A/T to the reman center.

Flattened or deformed O-ring . If the O-ring is flattened or deformed, replace the A/T. The O-ring can get damaged if the ATF pump seizes up and overheats. Make sure the problem has been fixed by connecting the HDS and testdriving the vehicle using the previous DTC P0740 or P0741 freeze data parameters (match the TPS and VSS values for at least 25 seconds ).

O-ring is OK . If the O-ring is round and in good condition, the most likely cause for DTC P0740 or P0741 to set is the A/T, the torque converter, or both. Install the reman A/T. Make sure the problem has been fixed by connecting the HDS and test-driving the vehicle using the previous DTC P0740 or P0741 freeze data parameters (match the TPS and VSS values for 25 seconds ). Before you install the reman A/T, make sure the O-ring on the torque converter is properly installed.


Hope helps.

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.

P0741 torque converter stuck off code - 2004 Toyota corolla


P0741 deals with internal transmission torque converter slip. A proper scan tool that is capable of reading the sensor's data inside the transmission would show the slipping torque converter and the fluid temperature.
It is critical to know exactly what conditions are present when the code stores. If the codes were not erased, they could be old codes in it's history.

Go back to the transmission shop or where you had the work done on replacing the TCC solenoid and have them read and clear the codes history. As mentioned, they could be old codes that is being read prior to your repairs.
Thank you for using Fixya and good luck, Have a shop verify line pressure, and provided no valves in the TCC hydraulic circuit are worn, replace the torque converter. Also, Lubegard Shudder Fix will at least fix this for awhile. Or try a transmission flush by a shop that uses BG brand products.

These codes comes out P0741


Your torque converter is not locking up.
The solution is to have the torque converter replaced and the transmission serviced.
Hopefully, you are still under warranty and can get it repaired it for free.
If not, it can get pretty expensive.
