Does a 1996 ford explorer 4.0 eddie baurer have a lock out torque converter


do you mean a Lock-up torque converter ? if so yes ford made electrically lockable torque converters since 94 ( all torque converters are hydraulic activated ,lock-up is proformed using a electric solenoid ) , but only certain transmissions made by ford had them , decode your vin number on left corner of dash to determine if you have E4od transmission or 4a400 model these have solenoid
I ask this because to my knowledge only race cars use a LOck out converter (aka "transbrake") for very high hp startss

P0740 honda odyssey


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.

My 1997 Mercury Grand Marquis transmission location of the torque converter lock up sensor


There is no part called the lockup sensor, the lock up occurs when the Vehicle speed sensor sends a signal to the Transmission control module that the truck has reached the minimum speed and throttle angle for lock up to take place, it then activates a switch inside the transmission that locks up the torque converter clutch.

Starts & run when put in gear shuts off, will restart 3.8eng will not move as though the trans is locked


There is a good chance that your torque converter is locked due to a torque converter lock-up solenoid malfunction. (pretty common) The torque converter lock-up solenoid is what locks the torque converter to put the transmission into overdrive. When they malfunction, it will cause the transmission to be stuck in overdrive at all times (this is not supposed to happen until the vehicle speed gets over 45 Mph). You must remove the side cover from your transmission to replace the torque converter lock-up solenoid.
Please also be advised that many of the solenoid malfunctions - especially on older, high mileage vehicles, are caused by dirt and debris in the transmission. This debris is usually caused by wear or breakage of internal parts (like clutches or bearings) in the transmission. I would recommend also pulling the lower pan and filter off to see what kind of debris is in the pan and evaluate whether this may be caused by a more serious problem.
