700r4 Converter Lockup Wiring Diagram

The 700r4 transmission is an automatic transmission that was produced by the General Motors Company. It was used in several different vehicles over the years, including the Chevrolet Corvette and Chevrolet Camaro. One of the features of the 700r4 transmission is the ability to lock up the torque converter, which can improve fuel efficiency and reduce wear on the transmission. In this article, we will discuss the wiring diagram for the 700r4 converter lockup and provide helpful information to get you started.

What is a Torque Converter?

A torque converter is a fluid coupling that connects the engine to the transmission. It allows the engine to continue running when the vehicle is at a stop, and it also provides a mechanical advantage to the transmission. The torque converter multiplies torque and allows the engine to produce maximum torque even at low speeds. Torque converters can be locked or unlocked, depending on the design of the transmission.

Why Lock the Torque Converter?

Locking the torque converter can improve fuel efficiency and reduce wear on the transmission. When the torque converter is unlocked, the engine is still turning even though the vehicle is at a stop. This results in wasted energy and reduced fuel efficiency. When the torque converter is locked, the engine is connected directly to the transmission, which reduces the amount of slippage and improves fuel efficiency. Additionally, locking the torque converter reduces wear on the transmission, which can extend the life of the transmission.

Wiring Diagram for the 700r4 Converter Lockup

The wiring diagram for the 700r4 converter lockup is relatively simple. The lockup solenoid is controlled by a single wire that is connected to the fourth gear pressure switch. The fourth gear pressure switch is located on the valve body of the transmission and is responsible for detecting when the transmission is in fourth gear. When the switch detects that the transmission is in fourth gear, it sends a signal to the lockup solenoid to engage the converter lockup clutch.

How to Wire the 700r4 Converter Lockup

The wiring for the 700r4 converter lockup can be done by following these steps:

  1. Locate the fourth gear pressure switch on the valve body of the transmission.
  2. Disconnect the wire that is currently attached to the fourth gear pressure switch.
  3. Attach a new wire to the fourth gear pressure switch.
  4. Route the new wire to the lockup solenoid.
  5. Attach the new wire to the lockup solenoid.
  6. Connect the other end of the new wire to the positive side of a 12-volt power source.

Please note that the wiring for the 700r4 converter lockup may vary depending on the year and make of the vehicle. Always consult a wiring diagram specific to your vehicle before starting any wiring work.
