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 still not go away after freeway driving.

I don’t think it is the dirty fluid and solenoid because Trans. Fluid is very clean and old solenoid actually working (test with click sound); however, I replaced with new one. I test the new solenoid before I replace it, that solenoid also have the click sound when tested.

I check recall on ECU software but only recall is for 2004 and 2005 Toyota Corolla (not 2007).

Anyone knows what’s going on?
