The 4L60E transmission typically uses Dexron VI automatic transmission fluid. The fluid capacity is approximately 12 quarts, though this can vary depending on whether the torque converter is also being drained.
DIY Maintenance for the 4L60E Transmission
For those who enjoy working on their vehicles, basic maintenance tasks like fluid replacement or filter changes can be done at home with the right tools and knowledge. Always consult your vehicle’s manual for specific instructions.
Cost of Rebuilding or Replacing the 4L60E Transmission
If your 4L60E transmission fails, you have two main options:
- Rebuild: A rebuild typically costs between $1,500 and $2,500, depending on the extent of the damage.
- Replacement: A replacement can cost upwards of $3,000, especially for new or high-performance units.
When to Seek Professional Help
While DIY maintenance can save money, certain issues require professional attention. If you’re dealing with severe transmission problems, consult a certified mechanic to ensure the job is done right.
Conclusion
The 4L60E transmission remains a popular choice for GM vehicles, thanks to its reliability, performance, and versatility. Whether you’re driving a family SUV or a high-performance muscle car, maintaining this transmission is key to ensuring a smooth and trouble-free driving experience.

Climate-Friendly Strategies to Cool the Atmosphere

It is known that air conditioning technology needs lots of energy. Cooling buildings account for 10% of our global electricity consumption. That’s bad news for global warming. Cooling the indoors contributes to the heat in the outdoors. This vicious cycle has contributed to the precipice of doom we are heading towards.
There are, however, energy-efficient solutions, both traditional and modern. In much of the world, energy-guzzling technology is powered by fossil fuels. These emit lots of greenhouse gases, which make the atmosphere hotter.
Better Air Conditioning Technologies
Nowadays, ACs have refrigerants running through their coils to absorb heat from the warm air. Some of them are literal greenhouse gases. You don’t want those leaking out of your unit. On top of that, air conditioners cool indoor spaces by pushing out the heat that refrigerants absorb. That means they make the immediate surroundings hotter, too.
There is no technological reason for ACs to use as much energy as many commercial models do now. In humid countries like India, Singapore, or parts of the US, about a third of the energy is used for managing humidity. While some modern models have a so-called dry mode to target humidity, air conditioners are still pretty bad at measuring how much moisture is in the air and determining how much needs to be expelled to maintain a comfortable temperature.
As a result, many people simply blast their ACs to over-cool the room and get the humidity down to the desired level. If ACs had better controls and sensing capabilities, they would be able to sense both the temperature and the humidity. By doing so, they would be able to optimize the performance of an air conditioner.
Pro-Tip: If you want to save up on electricity (specifically air conditioning) integrating energy-saving strategies in your Smart Home Automation system is a good idea. Xfinity offers a great smart home system with a feature that turns your electrical appliances off timely when they are not in use. They also have a more intelligent thermostat that tends to control the air conditioning more economically. Unlocking the features that save energy can be a challenge you can resolve by calling support on Xfinity phone number.
While the more efficient air conditioners are costlier upfront, you will save much more energy over the ten-year lifetime of that air conditioner. And therefore, the total cost of ownership is about half of the standard products. But that’s where the challenge lies. Either consumers don’t have the financial ability to spend that money upfront, or they are just not aware of it.
Construction of Cooler Buildings
Traditional architecture is the main solution to this problem. We see the manifestation of this in some modern buildings such as Qatar University, which uses wind towers to keep its buildings cool. Other Middle Eastern countries like Iran have been using this technology for centuries. These wind catchers are designed to trap fresh air and direct it indoors.
Additionally, noticing the sun’s orientation throughout the day and accommodating that in your façade design is imperative. Wind direction is a key parameter to design a good cross-ventilated building. Other solutions include shading devices and insulation. They keep the façade to a lower temperature and prevent heat from traveling through your roof.
You may also have noticed that houses in tropical zones are often white. Some countries like India paint roofs with lime-based whitewash, which absorbs less heat. This can reduce indoor temperatures by 2°C to 5°C.
How Different City Governments are Combating Urban Heat Island Effect?
The urban heat island effect is when urban areas like these get warmer than their surroundings because all this concrete absorbs and retains heat. There is also lots of waste heat from human activities like transport and, of course, air conditioning. Creating more spaces with shady trees and other plants lessens this effect.
The Colombian city of Medellin reduced average temperatures by 2°C only three years after planting green corridors. The interconnected network of greenery spans dozens of waterways and busy, polluted streets.
Minimizing heat expelled by cars also makes a difference. In Spain, Barcelona’s superblocks prioritize pedestrians and cyclists. But scale matters. The city’s Institute for Global Health estimates that 117 heat-related deaths could be avoided every year if hundreds more blocks were introduced.
Singapore is using a large-scale underground air conditioner, touted as the largest in the world, that cools residential buildings, banks, malls, and this iconic hotel. The technology is called district cooling, and it can save up to 50% on energy and emissions. That’s because having one big plant cooling an entire district makes it super-efficient. The water is chilled 25 meters below the ground before it is piped across different buildings.
Cities like Toronto, Paris, and Hong Kong are shifting rapidly to the model where they cool dozens of buildings with one central cooling system. In some cases, district cooling makes use of networks that already exist. Most of the system in Paris runs through the city’s sewage network.
District cooling is better suited for new constructions. For example, Gujarat International Finance Tec-City—also known as GIFT City.
Climate Action: A Responsibility, Not a Choice!
All of this may sound utopian, but like all other solutions, it requires lots of upfront capital, know-how, and of course, awareness. Still, experts say this type of investment is urgently needed—whether on a city-wide or neighborhood-scale or broader technological innovation. The good news is cooling doesn’t always have to look like this. But if we don’t move in a more sustainable direction fast enough, we risk staying trapped in a solution that is part of the problem.
