How do you connect a solenoid to a TCC transmission?

To connect your solenoid to the TCI® wiring harness, use the splice connectors provided. Connect the positive solenoid wire to the wire going to Terminal A on the wiring harness then connect the negative solenoid wire to the harness wire going to Terminal B. Install wiring harness and solenoid into the transmission.

Can a solenoid be wired into a TCI 376600?

A:The TCI® wiring setup does all of the switching on the ground side of the circuit. A one wire solenoid is self-grounded and therefore not able to be wired into the TCI® 376600. Q: How do I know if my solenoid is good? A:The first step in determining if your solenoid is serviceable is to test the electric coil.

Where do I get the TCC harness number?

To correct this problem, obtain case connector number 8634383 from a GM dealer. This will allow the TCI harness to snap into place. Using 18-gauge wire, run a 12-volt source to the red wire on the harness (Terminal A). Connect the vacuum switch to a ported vacuum source on the carburetor or throttle body.

Where is the transmission connector on a lockup TCC?

The final photo shows the underside of the transmission case connector – the white plastic piece is clipped into the transmission housing and there are plus that go into it from the top and bottom – it’s quite a complicated little piece!

Where is the lock up solenoid on a trans?

The trans are built to handle the stop and go so turning it off is not a problem. DO NOT just disconnect it and leave it at that. The Lockup solenoid is under the side cover. Sometimes the engine cradle needs to be lowered to get the side pan off. The solenoid is around $50.

What should I do if my solenoid lock up?

NEVER run the vehicle in gear when supported only with a jack. Chock the drive wheels and apply the parking brake. Before you begin this test, use a test light or multimeter to check for 12 volts to terminal A at the transmission. Once you’ve done so successfully, you can proceed with the following steps:

How to install a transmission lock up harness?

INSTALLATION INSTRUCTIONS (TRANSMISSION) 1. Remove the transmission oil pan bolts, carefully drain the transmission fluid and remove the pan. 2. Next, remove the transmission fluid filter by gently twisting and pulling down on the filter.

When does TCC lock up solenoid energize?

TCC lock-up solenoid is normally only energized in 4th gear, if the transmission temperature is above 250°F it will energize it in 2nd and 3rd as well. Duty cycle on the Pressure Control solenoid is inversely proportional to the throttle angle (as throttle angle increases, duty is decreased).

How to check if transmission lockup solenoid is working?

First we will verify if the transmissions lockup solenoid is functioning and if it’s a 2 wire or a 1 wire solenoid. 1. Connect the transmission connector plug to the transmission plug on the driver side and be sure it is plugged in securely. 2. Apply a 12V+ voltage to the loose pigtail of the connector plug. 3.

How many wiring harness connectors are in stock?

With over 350,000 wiring harness connectors in stock, you’ll never have to search anywhere else. Friendly, instant technical support How-to repair guides and OEM position statements Most connectors ship with terminals and 10″ of professional grade wire; ready to install.

When do I need to unlock the TCC on my car?

Since it’s hooked to a ported vacuum source, this means the switch is open at idle and when the engine is under heavy load – exactly when you want the TCC to be unlocked.

How is the torque converter clutch solenoid controlled?

The fluid pressure that applies and releases the torque converter lockup clutch is controlled by the torque converter clutch solenoid. The opening and closing of the TCC solenoid valve is controlled by the transmission control module (TCM) or powertrain control module (PCM), depending on the vehicle.

What is the signal switch on a TCC system?

The “TCC Signal Switch” appears to be a self-grounding normally open pressure switch that makes contact to ground whenever the TCC hydraulic system has pressure. If so, this is a much more interesting way to hook up the TCC Lockup Indicator.

What causes a TCC solenoid to disengage?

Power to the TCC Solenoid is provided through a switch on the brake pedal that interrupts power when the brakes are applied. This is what causes the lock-up to disengage in the test above. When the brakes are applied, the TCC should not be locked up, because power to the solenoid is removed.

What does the TCC solenoid do on a toque converter?

What Does The TCC Solenoid Do? The main function of the toque converter clutch or TCC solenoid is to send pressurized fluid to the torque converter’s clutch allowing it to achieve lock up in 4th gear based on a signal from the engine control module (ECM).

Where is the TCC solenoid located on a 4L60E?

In essence, the TCC solenoid is like a computer controlled on and off switch for your 4l60e’s torque converter lock up. Where Is The TCC Solenoid Located The 4l60e TCC Solenoid is located on the front passenger side of the transmission near the valve body. The image below shows the locations of various solenoids.

How is the solenoid connected to the transmission?

The TCC solenoid is connected to the valve body of the transmission. Disconnect the negative and positive terminals of the battery. Locate a body ground under the vehicle and attach one end of the 16-gauge wire to the body ground. Run the ground wire through the transmission wiring grommet, and attach it to the negative side of the TCC solenoid.
