I sounds like the TCC solenoid has failed. The stalling problem confirms that the TCC is engaged.

As a mechanic myself testing, trouble shooting and repair was not that difficult. Shift solenoid was very difficult to get to. Located under the head lamp passenger side.

This page explains how to change the transmission fluid but about half way down the page it tells how to check for the proper amount of fluid:

There isn't a transmission dipstick for this car.

SOURCE: honda torque converter clutch solenoid circuit

P0740 is a Torque Converter Clutch Circuit Malfunction, you will need to have just this circuit tested, it is mostly just a defective Torque converter clutch solenoid in the trans or a defective connection to the trans, u do not need another overhaul.

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.

P0740 Honda - Transmission Lock-Up Control System Fault Possible causes
- Low transmission fluid level
- Dirty transmission fluid
- Faulty torque converter clutch solenoid valve
- Torque converter clutch solenoid valve harness is open or shorted
- Torque converter clutch solenoid valve circuit poor electrical connection

Tech notes
On some Honda vehicles the P0740 code may be set by an overheating torque converter problem which is caused by an insufficient flow to the torque converter release circuit.

P0740 Honda Description
The torque converter clutch solenoid valve is activated, with the gear in D4, by the Transmission Control Module (TCM) in response to signals sent from the vehicle speed and the Engine Control Module (ECM). Lock-up piston operation will then be controlled. When the torque converter clutch solenoid valve is activated, the torque converter lockup clutch will engage creating a 1 to 1 RPM ratio between the transmission input shaft and the rotational speed of the torque converter.
Lock-up operation, however, is prohibited when A/T fluid temperature is too low.
When the accelerator pedal is depressed (less than 2/8) in lock-up condition, the engine speed should not change abruptly. If there is a big jump in engine speed, there is no lock-up.

Got this code p0740, tcc circuit malfunction, I would like to replace a TCC Solenoid how do i go about it?


P0740 - Torque Converter Clutch Circuit Open

Possible Causes:
- Low transmission fluid level
- Dirty transmission fluid
- Faulty torque converter clutch solenoid valve
- Torque converter clutch solenoid valve harness or connectors
- Torque converter clutch solenoid valve circuit is open or shorted

Check your fluids 1st if they are low add fluid, and if they are dirty do a flush and a new filter. This usually will take care of it and save you money. TCCSV is a bit pricey try the cheaper route first. But it is located inside the transmission or on the side of the transmission. I dont recall exactly. Its something I would let a shop do though unless you have high mechanical skills.

P0740 Torque Converter Clutch Circuit/Open
This means that the internal wiring for the Torque Converter Clutch or the clutch itself is burnt out or 'open.'

Good luck on this repair which will require a transmission tech to perform by opening up the transmission.
