Lockup Solenoids refer to electronic gadgets in automatic transmissions that lock the torque converter in certain circumstances, such as at highway speeds.

Where is the lock up solenoid on a axn4 transmission it is not getting a signal and it will not shift in to over drive?

The lockup solenoid does not control OD shift. The lockup solenoid controls torque convertor lockup. Torque converter lockup isn't a gear at all, but a fuel saving function that kicks in when you are cruising, which is a clutch in the torque converter that locks down and overrides the fluid coupling so you dont loose engine engine torque due to the normal fluid coupling of the torque converter. In effect, it overrides the torque converter completely, and provides a direct drive from the engine to the input shaft of the transmission. TC lockup does occur in OD, but it is a separate function. OD is achieved in the AX4N when the OD band holds the front planetary sun gear stationary. This is done by the OD servo and piston assembly, when fluid is directed there through a valve in the valve body. You could have a problem in any of those areas causing you not to have OD.

How do you change the torque converter solenoid on a 1997 sunfire and where is it?

Remove the transaxle side cover (behind left front wheel). You will see some wires coming from a plug at the top forward facing bit of the transaxle running (inside tranny) down, then rearward to a solenoid. Remove the one mounting screw from the solenoid and remove the solenoid and wires. Install new unit in reverse order. Always replace transmission filter when replacing lockup solenoid.

What is a TCC Solenoid circuit on a 2001 Nissan Frontier?

Torque Converter Control Solenoid. It controls the lockup clutch in the torque converter, when it malfunctions the clutch can fail to engage or disengage properly causing shuddering at speed and stalling at idle. It is found inside the transmission as part of the valve body.
