Introduction
The 700r4 lockup kit wiring diagram is an essential tool for anyone who wants to install a lockup kit in their transmission. The lockup kit helps to improve the performance of the transmission by locking up the torque converter when the car is cruising, which reduces slippage and heat buildup. In this article, we will guide you through the process of wiring a lockup kit to your 700r4 transmission.
We will cover everything from the tools you need to the step-by-step instructions on how to install the lockup kit. We have also included frequently asked questions and tables that will help you understand the process better.
Tools Required
Before you start wiring your lockup kit, you need to have the right tools. Below are the tools you will need:
| Tools | Description |
|---|---|
| Soldering iron | Used to join wires together |
| Wire stripper | Used to remove insulation from wires |
| Crimping tool | Used to crimp connectors onto wires |
| Electrical tape | Used to insulate exposed wires |
| Heat shrink tubing | Used to protect the wiring from the elements |
| Multimeter | Used to test the electrical connections |
Safety Tips
It is important to take safety precautions when working with electrical components. Here are a few safety tips:
- Make sure the car is turned off and the keys are removed from the ignition before starting work.
- Wear safety goggles to protect your eyes from debris.
- Work in a well-ventilated area to avoid inhaling toxic fumes.
- Do not touch any metal parts of the car while working to avoid electrical shock.
Step-by-Step Instructions
Follow these step-by-step instructions to wire your 700r4 lockup kit:
Step 1: Locate the Lockup Solenoid Connector
The first step is to locate the lockup solenoid connector. This connector is located on the passenger side of the transmission case, just above the pan rail. It is usually a four-pin connector, but some models may have a two-pin connector.
Use a multimeter to check the resistance between the two pins. The resistance should be between 10 and 15 ohms. If the resistance is outside of this range, you may need to replace the solenoid.
Step 2: Splice into the Lockup Solenoid Wiring
Use a wire stripper to remove 1 inch of insulation from the lockup solenoid wiring. Then, splice the wires from the lockup kit into these wires using a soldering iron or crimp connectors. Make sure to connect the wires according to the wiring diagram provided with the kit.
Step 3: Route the Wiring Harness
Route the wiring harness through the transmission tunnel and into the engine bay. Make sure to secure the wiring using cable ties or electrical tape to prevent it from rubbing against any other components.
Step 4: Connect the Wiring to the Switch
Connect the wiring from the lockup kit to the switch provided with the kit. The switch should be mounted in a location that is easily accessible from the driver’s seat.
Step 5: Test the System
Test the lockup kit wiring by starting the car and driving it around. The lockup kit should engage when you reach a speed of around 45 mph. Use the switch to turn the kit on and off to ensure that it is working properly.
Frequently Asked Questions
What is a Lockup Kit?
A lockup kit is a device that locks the torque converter in place when the car is cruising, which reduces slippage and heat buildup. This improves the performance of the transmission and can also result in better fuel economy.
Do I Need a Lockup Kit?
