The transmission fluid could be in need of a change, certain parts in the transmission depend upon clean fluid to move properly, this could cause the pressure sensor to fail and engage the torque converter to lock up at the right time. Timing is counted with the computer and it will flash lights when there is a problem.

Hello there my name is Clara I have a 2001 acura TL 3.2 liters thats reading the code P0740

P0740 is the torque converter malfunction code. The converter is in between the engine and transmission. The fluid that you are seeing is transmission fluid. It needs to go to a mechanic to narrow it down from there.

I have been getting the code p0740 it says something about the torque converter clutch circuit. it doesn't seem to be going into over drive. dose anyone have any suggestions I can try.

On some cars, there is a TCC solenoid in the transmission which can be replaced by removing the bottom pan. In some cars this solenoid can't be accessed without major disassembly.
