It sounds like the convertor in the exhaust system is partly blocked. You will need to have this checked at a shop. Frankster016

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.

Two codes coming up on car even after fixing alot on car now need to figure out low cost ways to fix P0744 & P0722 code issues spent 1,800 on car & have spent 1,400 already in parts & labor.


you need a better mechanic that traces ALL of the possibilities of each code, not just read the code and trow in a part hoping that it's fixed ~ it can be wiring as well, not just plug in a new part as mentioned on the 2nd trouble code to the vehicle speed sensor

P0744 Torque Converter Clutch Circuit Intermittent


P0722 Output Speed Sensor No Signal

the first of the 2 looks to be more intensive to trace and find out the problem & the 0722 is the easier job for an intermediate mechanic to trace the wiring for continuity

Code 743 means the computer did a volt drop test on the circuit and found the solenoid to be open or shorted to ground. It could be the solenoid valve, or the wiring.

What code po741


P0741 "Torque Converter Clutch Solenoid stuck off"
If the PCM detects high torque converter slip when the TCC is commanded ON, then DTC P0741 sets. The Powertrain Control Module (PCM) controls the Torque Converter Clutch Solenoid Valve (TCC Sol. Valve) Pulse Width Modulation (PWM). The solenoid controls the hydraulic fluid for TCC apply and release. When the TCC is applied, the engine is coupled directly to the transmission through the TCC. The TCC slip speed should be near 0.
Thank you for using Fixya and good luck

Auto transmission will not shift gears


Get diagnostics done and if you will get code P0741 - This trouble code is about damper clutch, which improves fuel economy by matching power transmission effectiveness of automatic transmission Damper clutch consists of control valve and solenoid valve which converts electric signal to hydraulic signal by the TCU signal. Corresponding code will be displayed under following conditions when damper clutch is operated form TCU lock-up output time. -when the difference between engine revolution and input shaft revolution has been below 160 RPM. Torque converter solenoid (TCU) is the last thing you should look at to replace, the cause of its failure might be in a different area like worn seals. Nevertheless it is a serious malfunction of a gearbox as further usage may end in a complete gearbox failure and the only solution you will be left with is to rebuild the gearbox or get a new one. Before you start buying parts you should closlely inspect the inner cover seals for uneven wear or possible damage, short cicuit will be caused by fluid passed onto electric connection,
