Ram 850RE Vs 8HP75 (In-Depth Comparison)
Transmission is an integral part of your vehicle. There are very few components in your car that is more important than the transmission system.
It is responsible for controlling the force and the speeds your engine disperses to the vehicle.
It is essential to have a top-functioning transmission system that helps smoothen your journey.
Two common transmission types are the 850RE and the 8HP75. How do they fare in comparison?
8HP75 is the better model compared to 850RE when you consider several factors. First, they both have a similar production source; however, the mode of operation of the two transmissions is different. So they may both serve their purposes depending on your preference and road use.
What is the Difference Between 850RE and 8HP75 Transmission?
The systemic and focus of each transmission type are different.
However, comparing the overall input of the transmission can help to make decisions on which one is best.
When using two other cars with both types of transmission, you often find that they are identical in output.
However, the apparent differences between these two in manufacture, hardware, operation, and many other aspects.
#1. The 850RE Transmission
850RE is a transmission with the trademark name Torqueflite, a product from the Chrysler Group LLC.
This transmission type is 8-speed automatic transmission. You will only find 850RE in cars with such standard features.
Another point to note about 850RE is the production format. The Chrysler Group designed and built the transmission in the US.
However, the design and license for this transmission are from the ZF 8HP transmission, a transmission from Germany.
#2. The 8HP75 Transmission
The 8HP75 is one of the many transmissions in the ZF 8HP series. It is a transmission from the German company, ZF Friedrichshafen.
Yes, the same company that provided the design and license for the 850RE. That explains the similarities between the two.
The HP in the 8HP75 stands for “Hydraulic converter” and “Planetary gearsets.” The HP explains the mode of operation of this transmission system.
One primary focus of this transmission type is to improve the engine’s fuel efficiency.
Both transmissions have a very close source of origin. However, irrespective of their basis of origin, they have significant differences worthy of note.
Which Transmission Type Produces more Power?
The main aim of your transmission system is to aid power production in the engine.
The power converts to the movement and functionality of your car. The modes of power production in the two transmissions are different.
While they both push to achieve the maximum power output of your engine, the transmissions go about it using different methods.
#1. Power Production in 850RE
The 850RE uses the redline system to produce more power in your car. The redline system is a way to keep the vehicle’s engine from overperforming.
The red line refers to the car’s revolution per minute (RPMs).
A higher RPM means your car continues to increase power production without meeting the redline.
The 850RE transmission has a higher redline, hence, a higher peak of performance for your engine. Several factors contribute to power production in your car.
A higher redline that the 850RE provides is one of those factors.
Admittedly, over time, a higher redline puts a strain on your engine because it continues to output power at a higher rate.
However, newer engine models have a failsafe system that cuts the fuel supply to the machine when it is running on the redline.
#2. Power Production in 8HP75
Maximizing power in the 8HP75 transmission is a different process. This transmission uses a compression ratio, unlike the higher revolution system in 850RE.
The compression ratio is a calculation of the movement of the piston in the engine.
The ratio compares the volume in the cylinder when this piston is at the bottom and the top.
A higher compression ratio means the engine compresses the air and fuel mixture inside the cylinder to a higher degree. What does this achieve?
It promotes more effective combustion of fuel. The compression ensures more fuel undergoes complete combustion.
Complete combustion ensures higher power output and reduced exhaust waste. In addition, this combustion method means fuel usage is at maximum capacity.
Therefore, one reason why many prefer 8HP75 is because of its higher fuel economy while producing maximum power.
Another advantage of this power production mode is that it gives you higher horsepower and torque, resulting in more power production for your car.
850RE vs. 8HP75: Which Transmission Type offers more Longevity?
The longevity of engines depends entirely on several reasons. Sometimes, it depends on how carefully you handle the transmission.
However, different transmission types have differing longevity under similar conditions and use.
#1. The 850RE Longevity
According to reports from many users, this 850RE is a reliable transmission type.
You know that an engine or compartment is only valid as long as it is reliable.
So, reliability is a significant factor in longevity. However, there have been issues with this transmission after use.
Transmission jerk during gear shifts is the most common complaint from any user. Problems with transmission fluids often cause these issues.
#2. The 8HP75 Longevity
The 8HP75 mode of operation means it has better transmission mechanics than 850 RE.
This operation module also ensures that it has more longevity and reliability.
You can continue to use this transmission as long as the proper component receives adequate fluid.
It also gives smoother control and better power distribution. Another reason why this engine promises better reliability is its smoothness during gear shifts.
Also, the components are more durable, meaning you can continue to use them for years, another reason why it is long-lasting.
Conclusion
The 8HP75 is an upgrade to the 850RE when you consider all factors. Both transmission types aim to increase power output.
However, the 8HP75 transmission increases fuel efficiency while maximizing power output.
It ultimately saves you the cost of running and maintenance. 8HP75 also offers durability and longevity. It is everything you need.
