If you’ve ever found yourself stranded on the side of the road, cursing at your vehicle’s transmission, you’re not alone. Especially if that transmission happens to be the infamous 46RE. This transmission is a bit like that mischievous cousin who’s always getting into trouble — it has a reputation for quirks and issues, but with a little love and care, it can go the distance. In this post, we’re going to dive deep into the world of the 46RE transmission. We’ll explore its common problems, and how to handle long-distance towing, and even dip our toes into the realm of DIY repair. By the end, you’ll be speaking 46RE like a pro!
1. Understanding the 46RE Transmission: A Quick Overview
The 46RE transmission, used in Dodge vehicles from the mid-90s through the early 2000s, is part of Chrysler’s line of electronically controlled automatic transmissions. Built to handle the torque from V8 engines, the 46RE has seen its fair share of both praise and criticism. The “RE” in its name stands for “Rear-wheel drive, Electronically controlled,” which hints at its electronic control module, a feature that’s both a blessing and a curse.
2. Common 46RE Transmission Issues: What to Look Out For
If you own a vehicle with a 46RE transmission, there are a few common problems that you should keep an eye on. Some of the most frequently reported issues include:
– Harsh Engagement: One of the first signs of trouble is a harsh engagement from Neutral to Drive (N to D) or Reverse (N to R). This could be an early indication that your transmission is wearing out.
– Slipping Gears: If your 46RE is slipping in and out of gears, particularly in reverse, it’s time to take action. Slipping is often a sign of worn-out clutches or a failing torque converter.
– Buzzing Sounds: A buzzing sound coming from the transmission is never a good sign. It could indicate anything from low fluid levels to more severe internal damage.
– Metal Shavings in the Fluid: Finding metal shavings in the transmission fluid is a red flag. This usually points to internal wear and tear, possibly from the clutch packs or other components.
These issues are not just minor annoyances; they are indicators that your transmission might be on its last legs. If you’re experiencing any of these problems, especially if you’re planning a long-distance tow, it might be time to consider a rebuild or replacement.
3. Towing with a 46RE Transmission: Proceed with Caution
Planning a long-distance towing trip with a 46RE transmission? It’s time to be cautious. The 46RE wasn’t exactly built with heavy-duty towing in mind, and if your transmission is already showing signs of wear, towing can push it over the edge. Before embarking on a 6,000-mile journey with a trailer in tow, consider the following:
– Transmission Cooler: Adding an aftermarket transmission cooler can help manage the extra heat generated during towing. Overheating is one of the leading causes of transmission failure, especially in the 46RE.
– Band Adjustment: Properly adjusting the transmission bands can help prevent slipping and improve overall performance. However, if you’re already noticing significant issues, this might be a temporary fix.
– Total Rebuild: If you’re hearing noises, experiencing harsh shifts, or finding metal shavings in your fluid, a rebuild might be your best option before hitting the road. Consider upgrading with heavy-duty parts if you plan to tow regularly.
4. To Rebuild or Not to Rebuild: That is the Question
So, you’ve diagnosed the issues, and now you’re faced with a decision: Should you rebuild your 46RE or simply replace it? Rebuilding might seem daunting, but it’s not as scary as it sounds. If you’ve got some mechanical aptitude and the right tools, it’s entirely possible to tackle a rebuild yourself.
Advantages of Rebuilding:
– Cost-Effective: A rebuild is usually cheaper than a full replacement, especially if you do it yourself.
– Customization: When rebuilding, you can opt for upgraded parts, such as a stronger torque converter or heavy-duty clutches, to make your transmission more robust.
– Learning Experience: If you’re a DIY enthusiast, rebuilding your 46RE can be a rewarding project. Plus, you’ll gain valuable knowledge for future repairs.
When to Consider a Replacement:
– Severe Damage: If your transmission is heavily damaged, with large chunks of metal or severe wear, a replacement might be the safer bet.
– Time Constraints: Rebuilding a transmission takes time. If you need your vehicle back on the road quickly, a replacement might be the better option.
5. The Importance of the Overdrive Unit in a 46RE
The overdrive unit in a 46RE transmission is often a point of debate. Some people consider skipping the rebuild of the overdrive unit, especially if they don’t plan on using it frequently. However, this can be a risky move. The overdrive unit is integral to the overall function of the transmission, and neglecting it could lead to future breakdowns.
If your overdrive is slipping, particularly when towing or going uphill, it’s best to rebuild this component along with the rest of the transmission. Remember, a chain is only as strong as its weakest link!
6. DIY Rebuilding Tips: Tools, Tricks, and Tutorials
Decided to take on the challenge of rebuilding your 46RE transmission? Awesome! Here are some tips to help you get started:
– Transmission Bench Videos: If you’re a visual learner, the videos on Transmission Bench are an invaluable resource. They offer step-by-step instructions for tearing down and rebuilding a 46RE transmission.
– Specialty Tools: While you won’t need an engineering degree to rebuild a 46RE, you will need some specific tools, like a shop press for compressing springs and a feeler gauge for checking clearances.
– Take Your Time: Rushing through a rebuild is a recipe for disaster. Make sure you have a clean, organized workspace and take your time with each step.
7. The Future of Your 46RE: Keeping it Running Smoothly
Once you’ve rebuilt or replaced your 46RE transmission, the key to longevity is maintenance. Regularly check the transmission fluid, avoid overheating, and be mindful of the weight you’re towing. With proper care, your 46RE can keep on trucking for many more miles.
In conclusion, the 46RE transmission may have its quirks, but with a little knowledge and the right approach, you can keep it running smoothly for years to come. Whether you’re towing a heavy load across the country or just cruising around town, understanding your transmission and addressing issues early on will save you from headaches down the road. Remember, when in doubt, rebuild — and don’t forget the overdrive!
So, the next time someone asks you about your 46RE transmission, you can confidently reply, “I’ve got it covered!”
Final Word: Don’t Fear the 46RE, Embrace It
The 46RE transmission might have a reputation, but with the right care and attention, it can be a reliable part of your vehicle. Whether you’re tackling a rebuild yourself or just looking to understand your transmission better, remember that knowledge is power. And when it comes to the 46RE, a little knowledge goes a long way. So, gear up, get your tools, and don’t be afraid to dive into the world of the 46RE transmission. You’ve got this!
