Flat towing a Jeep TJ automatic is a popular way to bring your vehicle along for adventures without needing a trailer. Many Jeep owners love flat towing because it saves money, is easier to set up, and lets you travel farther.
But it’s important to know exactly how to do it right. If you don’t follow the right steps, you can seriously damage your Jeep’s transmission, electrical system, or even create dangerous situations on the road.
Flat towing means pulling your Jeep with all four wheels on the ground. For the TJ model with an automatic transmission, there are extra steps compared to manual. This guide will cover every detail you need to safely flat tow your Jeep TJ automatic.
You’ll learn about the tools required, the correct setup, and some useful tips that many beginners overlook.
What You Need To Flat Tow A Jeep Tj Automatic
Flat towing isn’t just hooking up and driving off. You need some essential equipment to do it safely and legally.
- Tow bar: This connects the Jeep to the tow vehicle.
- Base plate kit: Attaches to your Jeep’s frame to secure the tow bar.
- Wiring harness: Allows your Jeep’s lights to work with the tow vehicle.
- Safety cables: Backup connection if the tow bar fails.
- Brake system: Required by law in many states; helps your Jeep stop when you brake.
- Transmission lube pump (for automatic): Prevents damage by keeping transmission fluid circulating.
- Tow mirrors: Extends your view around the Jeep.
Here’s a quick comparison of common equipment:
| Equipment | Purpose | Mandatory? |
|---|---|---|
| Tow bar | Connects Jeep to tow vehicle | Yes |
| Base plate kit | Mounting point for tow bar | Yes |
| Wiring harness | Syncs Jeep lights | Yes |
| Safety cables | Backup safety | Yes |
| Brake system | Assists braking | Varies by state |
| Transmission lube pump | Protects automatic transmission | Highly recommended |
| Tow mirrors | Improved visibility | Recommended |
Preparing Your Jeep Tj Automatic For Flat Towing
You can’t just jump in and go. Setting up your Jeep TJ automatic for flat towing requires careful attention, especially to protect the transmission.
Step-by-step Setup
- Install the base plate kit: Attach it securely to the Jeep’s frame.
- Connect the tow bar: Make sure all pins and locks are tight.
- Wire up the lights: Use a plug-and-play wiring harness for reliable lighting.
- Add safety cables: Cross them under the tow bar for extra protection.
- Set up the supplemental brake system: Follow instructions for your specific model.
Transmission Setup
Flat towing an automatic Jeep TJ is risky if you don’t use a transmission lube pump. Unlike manual transmissions, automatics need constant lubrication. If you tow without a lube pump, you risk burning out the transmission.
- Install the lube pump according to the manufacturer’s directions.
- Confirm it’s working before every tow.
Another option is to remove the driveshaft. However, this is not practical for most people, and it’s easy to make mistakes. The lube pump is safer and more convenient.
Jeep Transfer Case Settings
The Jeep TJ has a transfer case for 4WD. For flat towing:
- Set the transfer case to Neutral.
- Shift the automatic transmission to Park.
This keeps your wheels free to turn and prevents internal damage.
Checklist Before You Start
- All connections secured and checked
- Lube pump running
- Transfer case in Neutral, transmission in Park
- Brake system tested
- Lights working correctly
Common Mistakes When Flat Towing A Jeep Tj Automatic
Many people make simple mistakes that can cost thousands to fix. Here are the most common:
- Skipping the lube pump: This is the fastest way to destroy your transmission.
- Wrong transfer case setting: If you leave it in gear, you’ll damage the drivetrain.
- Loose tow bar pins: Can lead to separation on the highway.
- Forgetting safety cables: Legal trouble and unsafe towing.
- No brake system: Fines or accidents, especially in states where it’s required.
A surprising mistake is not checking the weight limits of your towing vehicle. The Jeep TJ weighs about 3,300 lbs. If your tow vehicle isn’t strong enough, you risk unsafe handling.
Here’s a comparison of common tow vehicle capacities:
| Tow Vehicle | Max Tow Capacity | Can Tow Jeep TJ? |
|---|---|---|
| Ford F-150 | 7,500 lbs | Yes |
| Honda CR-V | 1,500 lbs | No |
| Chevy Tahoe | 8,600 lbs | Yes |
| Toyota Corolla | 1,000 lbs | No |
Helpful Tips For Flat Towing
Flat towing can be easy if you follow these expert tips:
- Check tire pressure on your Jeep before every trip. Low pressure can cause wobbling.
- Use a tire pressure monitoring system for safety and quick checks.
- Practice turns and stops in a safe area before hitting the road.
- Take short breaks every 100 miles to inspect connections and fluid levels.
- Always carry spare pins, cables, and wiring adapters.
A non-obvious insight: If your Jeep has aftermarket bumpers, you might need special base plates or adapters. Always check compatibility before buying.
Another overlooked tip: Test your Jeep’s steering wheel lock. If it locks when the key is off, you must leave the key in the ignition (in the “off” position) while towing to avoid tire drag.
