Is the 4R70W Transmission Electronic?

The 4R70W transmission is an electronically controlled transmission that was introduced in the early 1990s. It is a four-speed automatic transmission that is widely used in a variety of Ford vehicles. The 4R70W has been succeeded by the 6R80 six-speed automatic transmission, but it remains in production for certain applications.

What Does 4R70W Stand For?

4R70W stands for 4-speed automatic transmission with a Lockup torque converter and Wide ratio gears. The 4R70W was introduced in the 1995 model year vehicles and is still in production today. It is used in a wide variety of Ford, Lincoln and Mercury vehicles.

How Heavy is a 4R70W Transmission?

The 4R70W transmission is a four-speed automatic transmission that was introduced in the early 1990s. It is a heavy duty version of the 4R70E transmission and was used in a variety of Ford vehicles, including the Mustang, F-150, Crown Victoria and Explorer. The 4R70W has a maximum torque capacity of 440 lb-ft and can handle up to 600 hp.

It is a reliable transmission but can be susceptible to overheating if not properly cooled.

What Cars Have a 4R70W Transmission?

The 4R70W is a Ford automatic transmission that was introduced in the early 1990s. It was used in a wide variety of vehicles, including the Mustang, Crown Victoria, and Explorer. The 4R70W is very similar to the AOD-E transmission, which was also used by Ford.

Both transmissions are four-speed automatics with overdrive. One major difference between the two transmissions is that the 4R70W has an electronically controlled valve body, while the AOD-E does not. This allows the transmission to be controlled by a computer, which can make shifts smoother and more precise.

The 4R70W was updated to the 4R75W in 2003. The only significant change was that the new transmission had an improved torque converter. The maximum torque capacity increased from 450 lb-ft to 500 lb-ft.

If you’re looking for a car with a 4R70W transmission, any late model Ford vehicle should have it. This includes Mustangs from 1994-2004 and Explorers from 1995-2001.

Does 4R70W Have Overdrive?

The 4R70W is a four-speed automatic transmission designed for longitudinal engine configurations. It is widely used in trucks and SUVs but also find its way into performance cars. The “4” denotes the number of forward gears, while the “70” refers to the torque capacity in lb-ft.

The W means it has wide gear ratios. The 4R70W has overdrive in fourth gear with a 0.70:1 ratio. That’s why it’s often called a “wide-ratio” transmission.

First gear is 3.0:1, second gear is 1.62:1, third gear is 1.0:1, and fourth gear is 0.70:1 .

4R70W Transmission Upgrades

4R70W Transmission Upgrades The 4R70W is a great transmission for anyone looking to upgrade their vehicle. There are many different ways to upgrade this transmission, and each has its own benefits.

Here are some of the most popular upgrades for the 4R70W: 1. Shift Kits: A shift kit is one of the most popular upgrades for the 4R70W. Shift kits improve shifting performance by reducing friction and improving fluid pressure.

This results in smoother, more consistent shifts that can help your vehicle perform better overall. 2. Torque Converters: Another popular upgrade for the 4R70W is a new torque converter. A higher quality converter can improve shifting performance and durability, and may even offer better fuel economy.

If you’re looking to get the most out of your 4R70W, a new torque converter is definitely worth considering. 3. Valve Body Upgrades: The valve body controls the flow of hydraulic fluid in the transmission, and upgrading it can result in significant improvements in shifting quality. Many aftermarket companies offer upgraded valve bodies for the 4R70W, so finding one shouldn’t be too difficult.

4. Trans Brakes: A trans brake is a device that helps to hold your car stationary when launching from a stop light or roll racing start line .

4R70W Problems

If you’re driving a Ford with a 4R70W transmission, you may eventually have some problems with it. Here’s what you need to know about the most common 4R70W problems and how to fix them. 1. Slipping Gears

One of the most common 4R70W problems is slipping gears. This can happen for a variety of reasons, but the most common is low fluid levels. When your transmission fluid gets low, it can cause the gears to slip and not engage properly.

You may also have this problem if your transmission filter is dirty or clogged. Either way, the fix is relatively simple: just add more fluid or change the filter. 2. Hard Shifts

Another common issue with the 4R70W is hard shifting. This can be caused by a few different things, but again, low fluid levels are often to blame. If your transmission fluid is low, it won’t be able to lubricate the gears properly, causing them to grind against each other when they shift.

This can also be caused by dirty fluids or a clogged filter. The solution here is the same as for slipping gears: add more fluid or change the filter. 3. Leaking Fluid

Leaking transmission fluid is another problem that can plague the 4R70W. There are a number of seals and gaskets in the transmission that can wear out over time and allow fluid to leak out. If you notice any leaks, it’s important to get them fixed as soon as possible so that your transmission doesn’t run dry and cause even more damage.

4R70W Performance Transmission

The 4R70W is a performance transmission that was introduced in the early 1990s. It was designed to be a replacement for the older 4R60 transmission. The 4R70W is a four-speed automatic transmission that is capable of handling up to 700 ft-lbs of torque.

It has been used in a variety of vehicles, including the Ford Mustang, F-150, Explorer, and Crown Victoria. One of the main benefits of the 4R70W transmission is its ability to handle increased levels of torque. This makes it an ideal choice for performance applications where extra power is needed.

Additionally, the 4R70W features a wide variety of aftermarket parts and upgrades that can further improve its performance and capabilities.

4R70W Upgrade Kit

If you’re looking to upgrade your 4R70W transmission, there are a few things you’ll need to consider. A quality upgrade kit will include a new torque converter, valve body, and shift kit. You may also want to consider upgrading the transmission cooler and lines.

The most important part of any 4R70W upgrade is the torque converter. A higher quality converter will offer better performance and durability. The valve body is also an important consideration.

A good valve body will improve shifting quality and help prevent transmission problems down the road. A shift kit can be a great addition to any 4R70W upgrade. A shift kit helps improve shifting quality and can make your transmission shifts smoother and more precise.

Transmission coolers and lines are also worth considering if you’re looking for the best possible performance from your upgraded transmission.

Conclusion

In order to build a bulletproof 4R70W, there are several things that need to be done. First, the transmission must be completely disassembled and all of the old parts must be replaced with new ones. Next, the transmission must be properly serviced and all of the fluid levels must be checked.

Finally, the transmission must be properly reinstalled and tested to ensure that it is working correctly.
