All You Need to Know the 47RE Transmission and the Way it Affects the Performance of Your Car
The 47RE transmission is a very important transmission to numerous owners of trucks and SUVs particularly to owners of Dodge Ram and others like them. The 47RE transmission was preferred with heavy duty vehicles because it was highly durable and versatile and was especially desired by those consumers who want a strong performance and towing capacity. No matter whether you are a novice in car performance tuning or a veteran mechanic, it is of great importance to be aware of the power of the 47RE transmission, its drawbacks, and possible improvement means.
This article will go through the functionality of the 47RE transmission, the performance considerations of the transmission and the typical upgrades to the transmission to help make you more educated to get the most out of your 47 RE transmission. So what is special about this type of transmission system and how can we best maximize its performance.
What is the 47RE Transmission?
47RE transmission is an automatic transmission (4 speeds) which was launched by Chrysler to be a replacement of 46RE. It is built purposely to deliver heavy duty performance like in Dodge Ram heavy duty towing capacities. The 47RE comes with the features of a higher torque capacity and the reliability that comes in handy to a strong engine.
The 47RE differs with the manual transmissions in that it has auto shift system, facilitating ease of operation to the driver by the fact that the changes are smooth. The main degree factors that render the 47RE functional are its hydraulic control system, torque converter and gear ratios, which together create a symbiosis to regulate the engine power of the vehicle and provide the vehicle with maximum efficiency.
The 47RE Transmission Performance and Durability.
The 47RE transmission has been one of the most preferred transmissions when it comes to truck persons because of the robust performance that the transmission boasts of. It can transmit a maximum of 440 lb-ft torque and is therefore suited in vehicles that need high towing and hauling abilities.
Durability and Problematic areas
Although the 47RE transmission has been an efficient equipment regarding durability, it is not invulnerable. The frequently occurring problems are slipping, rough shifting, and overheating. Slipping is common in cases of aging or contaminated transmission fluid whereas rough shifting may indicate the wear of the parts. Another shortcoming experienced by the owners of cars using this transmission is overheating which normally occurs due to overloading in towing large loads without cooling before loading.
Overall, many of these problems can be avoided by performing routine maintenance including fluid replacement and cooling system verification which will add years onto the life of the 47RE transmission.
Enhancements and Improvements towards Betterization Enhancements and Improvements towards Betterization
Other owners prefer making an improvement on the 47RE transmission to improve its performance generally and most especially among high-performance and heavy-duty vehicles.
The common upgrades are:
Upgraded Torque Converters: A new improved torque converter is able to make significant gains in terms of towing capacity and overall acceleration in the vehicle. Such converters minimize slip and transfer more power through the assembly to the transmission.
Shift Kits: The shift kit is the modification that lets the driver to set his own shift points which can result in quicker shift response and shift performance particularly at the load.
Transmission Coolers: It is strongly advised to add an extra transmission cooler and it is especially important in the case an individual tows frequently or carries heavy items. The cooler assists with the appropriate operating temperature making the 47RE transmission to last longer with the risk of overheating being minimized.
Harder Valve Bodies: The valves body is responsible of regulating the weight of fluids and pressures in the transmission. High-performance valve body enhances responsiveness of transmission and its shifts to make it smoother, quicker and harder under load that conditions.
Specifications 47RE Transmission Relating Engine Specs
The 47RE transmission mostly goes with power plants, which are of high-torque nature, and thus this combination makes it the right fit in heavy duty engines. Typical engine combinations match with the 47RE transmission as below:
5.9L Cummins Turbo Diesel: This is one of the most sought engines that is coupled with the 47RE transmission mainly on the Dodge Ram 2500 and 3500. The 5.9 L Cummins engine has great torque and 47RE transmission is effectively able to deliver it.
5.2L and 5.9L Gas Engines: These are the engines that are not powerful compared to the diesel-powered one; however, they can provide high torque that suits 47RE transmission in small trucks or SUVs.
The transmission system has been designed to facilitate the heavy load and torque produced by these engines providing power and control during operation.
Comfort & Interior designWhat the impact of the 47RE on driving experience?
Although the 47RE transmission is rather concentrated on mechanical results, the influence on the interior design of the car and driving comfort thereof cannot be underrated. The 47RE can create a smoother experience in shifting and will deliver such experiences as compared to the older and more rigid transmission systems.
Besides, the automatic 47RE makes sure that drivers no longer have to worry about manually adjusting the gears as they can focus on the drive, and on controlling the vehicle. This proves very helpful especially in cases where there is heavy-towing or city-driving as manual control when it comes to gearing can be tiresome and distracting.
Typical Maintenance Recommendations to Cause 47RE Transmission to Live Longer
The best way to make your 47RE transmission last as long as possible is by observing a regularly maintenance schedule. The following are some of the tips:
Transmission Fluid: Look at the level frequently. Low or dirty fluid will make it slip in and shift roughly. The level of transmission fluid and its quality should be monitored.
Filter and Fluid: The fluid must also be changed on an interval basis so as to operate smoothly. Be sure to replace the oil and filter at every change interval recommended by the manufacturer.
Add an Auxiliary Cooler: This would especially be effective if you need to tow regularly and this would keep the transmission within its operating limits by cooling it.
Slipping/Rough Shifting Conditions: When you suspect that there is a problem with shifting, or performance of any kind, then it is significant to make sure that they are addressed soon enough to advise against expensive reconstruction.
Expert opinion on the 47RE Transmission
Jim Lentz is a transmission expert and according to Lentz, 47RE transmission is usually underestimated in regards to performance and lifespan. In most cases it can last more than 200,000 miles when well taken care of. Its main strengths, however, are frequent service and suitable improvements to those who utilize it to the maximum.”
The suggestion of Lentz emphasizes the necessity of maintenance, which means that the 47RE transmission can be overloaded, though, this should be done with appropriate care and attention.
Results: The 47RE Transmission- It is a good option in performance and longevity.
The 47RE transmission is a superior and strong transmission that can be used by those drivers who expect high performance in the car and more so evident in the truck and SUV segments. Be it towing heavy loads, navigate through rough terrains or just having a good ride this transmission is designed to give it.
With just a little knowledge about its strengths and weaknesses and knowing what upgrades to make, you can make sure that your 47RE transmission keeps going strong and performing optimally in years to come. With proper care (combined with proper upgrades), your transmission can be kept running smoothly and spare you the grief of getting stranded somewhere.
