Some 2004 - 2005 model year Corolla vehicles may exhibit M.I.L. "ON" with DTC P0741 (Torque Converter Clutch Solenoid Performance). Production changes have occurred to correct this condition. Follow the repair procedure to address those vehicles that exhibit the condition.
NOTE :The repair procedure must be followed closely to assure that only the affected part is replaced, as multiple possible causes are listed.
^ 2004 - 2005 model year Corolla vehicles equipped with 1ZZ-FE engine produced BEFORE the Production Change Effective VIN shown below.
SO THAT MEANS BEFORE VIN # 1NXBR3#E#52369427

R & R of the Speed Sensor, Transaxle, and Torque Converter Clutch Assembly are covered under the Toyota Powertrain Warranty. This warranty is in effect for 60 months or 60,000 miles, whichever occurs first, from the vehicle's in-service date.
R & R of the Engine Control Module is covered under the Toyota Federal Emissions Warranty. This warranty is in effect for 96 months or 80,000 miles, whichever occurs first, from the vehicle's in-service date.
See if you can get anything resolved through Toyota first. Hope this helps, good luck.
I own a transmision shop common problem with these transmissions. The stator bushings wear out. Generally recommend soft part overhaul torque converter and sl solenoid most of the time this takes care of the concern however sometimes there are computer issues along with the previous mentioned. Hope this helps
I being a master auto mechanic for 27+ yrs have taken on this issue w a recent customer. The corolla is a 2007 (12/06) w 90k on it. I checked the code - (p0741) was present. I drove car on a highway road test (9.4 miles) to check TCC lock up solenoid operation. All worked perfectly. Checked vin if ECU was a recall candidate; No, it's not. Checked fluid; on a white rag it left grayish color. (Trans fluid should be red.. as it wears, brownish it becomes not grayish-Brown.) Removed trans cooler lines and flushed out cooler till it was clean. Hooked up inlet line into a 5gallon jug of fresh trans fluid, while the outlet line into an empty 5 gallon hug. Started car on lift and ran car thru it's gears until fluid was cleared of grayish fluid. Reinstalled cooler hoses. Drove car again w a pressure gauge teed into cooler lines. Also used my Verus, watched TCC solenoid operation w a lab scope that I backprobed into the ECU too see if EcU is working properly. Drove this for a (9.4 mile ) on part highway & local roads. All was good. Rechecked fluid - clean. As this point, being fair to customer, I told him too PAY ONLY FOR FLUID used and get back to me after he puts 200 miles on it. If light comes on again, then I will take another approach. Customer was pleased beyond belief with all that time spent but only paying for fluid. If after 200 miles goes by without light reappearing, then I would charge him the labor ($265)... He agreed. I will keep everybody posted if light reappears.
Just a update for anyone dealing with a code p0741 (have a 2008 kia sportage 149,000 miles) ... Start off by checking your fluid level, color, smell and if all checks out It's probably your TCC Solenoid (torque clutch converter solenoid) I had thought the worse case scenario and told myself I would just drive the car until the transmission fails completely but then I asked for a quote and the independent transmission shop owner said he would check it for free and run a diagnostic test on it. I got a call about a hour after dropping it off saying it was exactly what I thought it was the TCC solenoid and it would be a $475 fix! Find a local transmission shop and read through every single one of their reviews! Your transmission is important and one simple fix could make it last for many more years!
I started having this issue a couple years ago with my 96 Camry with 300k miles on it. Due to the age of the car I decided to just leave it and it has been driving great. I have put probably 20k miles on it while this code was on. As far as I can tell the only consequence is slightly reduced highway mpg (about 2 mpg less). I think the ECM does not even attempt to lock the torque converter when you have this code, so if you have an older car that you just need to get you around it probably isn't worth fixing.
On my V6 Camry the solenoid is located on top of the valve body inside the transmission, so you would have to drop the pan and remove the valve body to access it. The solenoid is not cheap either, so I don't think I am going to spend that much time just to gamble and see if it might fix the issue.
This code alone shouldn't make any difference on your emissions besides the slight mpg drop, but if you live in state that automatically fails you for a check engine light then you can usually just reset it by disconnecting the battery. Mine doesn't usually come back on for a couple hundred miles.
This is a super annoying thing.. hadn't had the code come on for a year.. got oil change at same place it went on the first time at and it came on almost immediately.. didn't get trans fluid changed.. but they did test the levels....cel turned off and on for a couple weeks and only problem was I needed inspection and it came on the day I made my appt.. :\ sheesh.. passed inspection after he reset and I came back.. but! The light came back on my drive home.. lmao.. but that was the last I've seen of it for a few months again.
This code is dumb. My new used car shifts jumpier than the Toyota matrix that this code pops up on now and again... & major reason why I got a new car cause wondering if the matrix gonna crap out soon.. if your car isn't shifting weird and you have over 150,000 miles prob not worth investing loads into this issue as from what I've seen usually comes back on anyways even sometimes after people get trans completely rebuilt! pain in butt if cel goes on when you are going to get an inspection.. but otherwise something seems fishy with this code honestly..
I have a 2007 Toyota Corolla CE with only 80,000 miles.
The Check Engine Light come on with error code P0741. I reset code by disconnect Battery.
1) I changed the Trans. oil with OEM toyota Type iv 3 times and the CEL still on once a while.
2) I dropped the pan and replace the transmission filter and replace the TCC lock up solenoid made by Rostra.
3) I check the old TCC solenoid and it is working except it has little dirt on the screen.
4) The CEL still on after all the above works.
5) Today, I reset again and then I use LubeGard and CEL come on again after freeway driving 50-60 mph.
I don’t think it is the dirty fluid and solenoid because Trans. Fluid is very clean now and old solenoid actually working (test with click sound); however, I replaced with new one. I test the new solenoid before I replace it.
I check recall on ECU software but only recall is for 2004 and 2005 Toyota Corolla (not 2007).
Anyone knows what’s going on?
Same problem I had 2007 Toyota Corolla traded it in
Rebuilt transmission replaced computer wiring messed up wasted 5 grand 180 k on car traded it you can rent car for month cheaper give them time to find problem
