P0741 on a 2017 Toyota Camry
Torque Converter Clutch Stuck Off
What does P0741 mean on a 2017 Toyota Camry?
P0741 is set when the ECM (or TCM) commands the torque converter clutch (TCC) to lock up under cruise conditions and does not see the expected drop in engine RPM relative to vehicle speed. Effectively, the lockup clutch is being commanded but not engaging — or it engages and immediately slips. Either way the converter is running in fluid-coupling mode at highway speed when it should be mechanically locked.
Symptoms on a 2017 Toyota Camry
- Check Engine Light is illuminated
- Engine RPM at highway cruise is 200–400 RPM higher than normal
- Noticeable fuel economy drop on the highway
- Possible transmission fluid overheating warning on towing
- Shudder or vibration at light-throttle cruise (slipping TCC)
- Often paired with P0700 from the TCM

How to diagnose this on a 2017 Toyota Camry
-
Check transmission fluid level and condition
Transmission service procedures vary widely — some vehicles require a special procedure to check fluid level at operating temperature with the engine running. Follow the vehicle's specific procedure. Fluid that smells burnt or shows clutch material indicates internal damage; no point chasing the solenoid until the fluid is right.
Tools: Vehicle-specific service procedure, Replacement fluid (if needed)
-
Verify TCC command vs. actual lockup with a scan tool
During highway cruise, watch the TCC duty cycle or commanded state, alongside engine RPM and vehicle speed. The TCC should command on around 45–55 mph and engine RPM should drop 100–300 RPM at the moment of lockup. No RPM drop confirms the TCC is not engaging mechanically.
Tools: Scan tool with TCC and live RPM PIDs
-
Test the TCC solenoid electrically
Locate the TCC solenoid in the wiring diagram (most are accessible through the transmission's external connector). Measure resistance — typical 10–30 Ω depending on the transmission. Confirm continuity and that the TCM commands voltage to the solenoid during the lockup attempt.
Tools: Multimeter, Wiring diagram
-
Inspect transmission external connector for fluid
Disconnect the external transmission connector. Fluid wicking up into the wiring harness from a failed case seal will contaminate the TCM-side connector and cause electrical faults that mimic a solenoid failure. The repair is the seal and often the harness; the solenoid itself may be fine.
Tools: Connector unlock tool, Flashlight
-
Drop the pan and inspect the magnet
A pan magnet covered in fine clutch material — especially brown or black gritty paste — indicates the torque converter clutch has been slipping and shedding material. At that point the converter must be replaced; cleaning is not a fix.
Tools: Drain pan, Socket set, New filter and gasket
Known Technical Service Bulletins for the 2015-2019 Toyota Camry
Manufacturers publish Technical Service Bulletins (TSBs) when a known issue affects a specific vehicle. These bulletins come from the NHTSA database for your Toyota Camry.
- ENGINE Feb 12, 2026
This bulletin includes basic procedures for performing a rescue charge on Ni-MH high voltage (HV) batteries. This bulletin should be used in conjunction with the applicable model and model year Repair Manual while performing a rescue charge. The GRX-5100 should be used wherever the Repair Manual references the Toyota Hybrid System (THS) charger.

Some 2005 – 2026 Toyota vehicles that have undergone water intrusion may exhibit a condition in which a musty odor is present. Follow the procedures in this bulletin to remediate the odor and address this condition. The purpose of this Service Bulletin is to provide general guidelines and procedures for odor remediation. This Service Bulletin provides a guide on how to prepare and treat the interior of the vehicle for odor remediation. Refer to the applicable model and model year Repair Manual and the EPA (Environmental Protection Agency) website for the most up-to-date safety and precautionary guidelines.
NHTSA #11028712 - ELECTRICAL SYSTEM Jun 12, 2025
The air conditioning dye injection tool kit has been developed to aid in identifying the location of air conditioning refrigerant leaks. The procedures outlined in this Service Bulletin aid in locating, inspecting, and repairing refrigerant leaks.
NHTSA #11020657 - STRUCTURE Dec 5, 2024
To prevent brake rotor rust from forming during transportation and storage, wheel film will be used instead of a cardboard type of anti-rust cover. The purpose of the wheel film is to shield the disc brake rotor from weather elements and initial rust before the vehicle is delivered to the customer. Consequently, the film should remain on the wheel for as long as possible.
NHTSA #11012743 - STRUCTURE Dec 5, 2024
The condition known as acid rain is caused by airborne chemicals or particles in the atmosphere, which mix with rainwater, nighttime dew, or high humidity to form acidic compounds. If these contaminants settle and remain on a painted vehicle surface, especially the horizonal areas of the hood, roof, and decklid, significant damage can occur. This damage is the result of actual etching of the paint and appears as pitting or water spots. As acid rain droplets on the vehicle surface evaporate, the concentration strength of the acid increases, causing deeper and more rapid damage. This evaporation and corrosive action also occur more rapidly on dark colored cars as direct sun heat increases. It is the dealer’s responsibility to protect and maintain the quality of the vehicle’s paint finish after receipt at the dealership prior to the first sale. In areas known for high frequency and/or concentration of acid rain, frequent vehicle washing during high heat or humidity periods will minimize the potential for paint damage caused by acid rain. It is further recommended that either reverse osmosis or deionized water be used to prevent water spotting.

About the 2015-2019 Toyota Camry
The 2015-2019 Toyota Camry was commonly sold with the following powertrains: 2.5L I4, 3.5L V6, 2.5L Hybrid I4. Common trims include LE, SE, XLE, XSE.
How to tell solenoid failure from converter failure
Both produce P0741, but the symptoms differ slightly:
- Solenoid failure — RPM at cruise is exactly normal-plus-converter-slip (around 200–300 RPM high). The transmission shifts cleanly otherwise. No shudder.
- Converter slipping — RPM at cruise is variable and rises under load. Light-throttle cruise produces a shudder you can feel through the seat and the steering wheel — described by owners as “feels like driving over rumble strips.”
The shudder pattern is diagnostic: solenoid issues don’t shudder; worn TCC friction material shudders during partial lockup.
P0741 with shudder is a transmission job
Once the TCC friction lining is worn to the point of slipping under light load, the converter shedding material accelerates downstream wear in the transmission itself. Driving a P0741 with shudder for months can convert a $1,800 torque-converter-only repair into a $5,000+ rebuild. Treat shuddering P0741 as urgent.
Trans fluid changes after P0741 — proceed with caution
For decades the rule was “if the transmission is starting to fail, do NOT change the fluid — the new clean fluid washes out gunked clutch material and the transmission fails immediately.” Modern fluid technology has changed that advice. A drain-and-fill (not a flush) with the correct OEM fluid is now generally safe and sometimes resolves P0741 if the fluid was degraded. A full machine-flush on a transmission with TCC slip is still risky.
