Dodge Transmissions: Everything You Need to Know About Performance, Problems, and Maintenance
When it comes to American muscle and rugged utility vehicles, Dodge is a name that stands out. Whether it’s a Dodge Ram, Charger, Challenger, or Durango, these vehicles are known for their power and durability. But no matter how strong the engine is, it’s the transmission that ultimately delivers that power to the wheels. Dodge transmissions have evolved over the years, offering better performance, fuel efficiency, and driving comfort.
In this guide, we’ll take a detailed look at Dodge transmissions, including the types available, common problems, maintenance tips, replacement costs, and how to choose the best option for your vehicle.
What Is a Transmission and Why Is It Important?
A transmission is a critical component of your vehicle’s drivetrain. It transfers power from the engine to the wheels and allows you to change gears, whether automatically or manually. Without a properly functioning transmission, your Dodge vehicle won’t shift gears smoothly—if at all.
Types of Dodge Transmissions
Dodge has used various transmissions throughout its lineup, including:
1. Automatic Transmissions
Most modern Dodge vehicles are equipped with automatic transmissions, which change gears without driver input. Popular models include:
-
TorqueFlite 8-speed automatic (used in modern Chargers, Challengers, and Rams)
-
A518 / 46RE / 47RE (found in older Dodge Ram trucks)
-
545RFE / 68RFE (common in Dodge Durango and Ram 1500/2500 series)
2. Manual Transmissions
Though less common today, manual transmissions were once a staple in Dodge muscle cars like the:
-
Dodge Challenger SRT
-
Dodge Viper
-
Dodge Neon SRT-4
Popular models include the Tremec TR-6060 and NV4500 used in heavy-duty and performance vehicles.
3. Continuously Variable Transmissions (CVT)
Some smaller Dodge models, like the Dodge Caliber or Journey, have used CVTs. These offer improved fuel efficiency but are less preferred in performance settings.
Notable Dodge Transmission Models
Here are some of the most well-known Dodge transmission models and what vehicles they’re associated with:
| Transmission | Type | Vehicle Models | Notes |
|---|---|---|---|
| 545RFE | Automatic | Dodge Durango, Ram 1500 | 5-speed automatic |
| 68RFE | Automatic | Ram 2500, 3500 | Heavy-duty use |
| 8HP70 | Automatic | Dodge Charger, Challenger | 8-speed smooth-shifting |
| TR-6060 | Manual | Challenger SRT, Viper | High-performance |
| 42RLE | Automatic | Dakota, Nitro, Liberty | Mid-size SUV/pickup |
Common Dodge Transmission Problems
While Dodge vehicles are reliable, several transmission issues have been reported across different models and years. Here are the most common:
1. Rough or Slipping Gear Shifts
Many owners of Dodge Ram trucks (especially those with the 68RFE) report slipping gears, especially when towing heavy loads.
2. Transmission Overheating
This is a common issue in high-mileage or heavy-duty usage, particularly in trucks and SUVs.
3. Failure to Shift
Some models like the Charger and Durango experience a delay or failure to shift from park to drive.
4. Check Engine Light
Transmission-related error codes like P0700, P0731, and P0740 are common indicators of problems.
5. Fluid Leaks
A transmission fluid leak can cause low pressure, overheating, and ultimately failure if not addressed.
Signs Your Dodge Transmission Needs Attention
Recognizing early signs of transmission trouble can save you thousands in repair costs. Watch for:
-
Grinding or shaking when shifting
-
Burning smell (may indicate overheating)
-
Delay in acceleration
-
Transmission slipping out of gear
-
Warning lights on the dashboard
Dodge Transmission Maintenance Tips
Preventive maintenance is key to keeping your Dodge transmission running smoothly. Here are some essential tips:
1. Check Transmission Fluid Regularly
Ensure the fluid is clean (reddish in color) and at the proper level. Dirty or low fluid can cause performance issues.
2. Use OEM-Approved Fluid
Always use the manufacturer-recommended transmission fluid, especially for Dodge vehicles with specific requirements like ATF+4.
3. Flush Transmission at Recommended Intervals
Typically every 30,000 to 60,000 miles, depending on your driving conditions and model.
4. Avoid Aggressive Driving
Frequent hard acceleration and towing heavy loads without proper cooling can wear out your transmission faster.
5. Install a Transmission Cooler
This is especially important if you tow or drive in hot climates. It helps reduce overheating.
Dodge Transmission Rebuild vs Replacement
When your transmission fails, you have two main options: rebuild or replace. Here’s a quick comparison:
| Option | Description | Cost Range | Pros | Cons |
|---|---|---|---|---|
| Rebuild | Replaces only worn parts | $1,500 – $3,500 | Cost-effective, retains original unit | Labor-intensive, may not fix all issues |
| Replacement | Entire unit replaced (new or remanufactured) | $2,500 – $5,000+ | Reliable, often under warranty | More expensive |
How Much Does a Dodge Transmission Cost?
