4L80E Valve Body Torque Specs

The valve body torque specs for a 4l80e transmission is 30-40 ft/lbs.

4l80e valve body torque specs

The 4L80E is a four-speed automatic transmission from General Motors. It is designed for rear-wheel drive vehicles and is the successor to the Turbo Hydramatic 400 transmission. The 4L80E features a lock-up clutch in the torque converter and is electronically controlled.

The 4L80E transmission has a cast aluminum valve body with a separator plate between the transmission fluid and the solenoids. The valve body bolts to the transmission case and has passages that direct transmission fluid to the various valves and solenoids. The 4L80E transmission has six valves and four solenoids.

The four main control valves in the 4L80E are the Pressure Control Valve (PCV), the Forward Clutch Apply Valve, the Reverse Clutch Apply Valve, and the Modulator Valve. The PCV regulates the pressure of the transmission fluid. The Forward Clutch Apply Valve controls the apply of the forward clutch. The Reverse Clutch Apply Valve controls the apply of the reverse clutch. The Modulator Valve controls the line pressure and modulates the shift feel.

The 4L80E transmission has a variety of sensors that provide input to the transmission control module (TCM). These sensors include the vehicle speed sensor, the turbine speed sensor, the output shaft speed sensor, the fluid temperature sensor, and the pressure switches.

What Are The Torque Specs For The 4l80e Valve Body?

There are no torque specs for the 4l80e valve body.

If you’re rebuilding a 4l80e transmission, or simply replacing the valve body, it’s important to know the torque specs for the various parts. This guide will give you the torque specs for the 4l80e valve body, as well as a few tips on installing it.

The first step is to remove the old valve body. You’ll need a few tools for this, including a ratchet and socket set. Once the old valve body is out, you’ll need to clean the surface of the transmission where the new valve body will be installed.

Next, you’ll need to install the new valve body. Be sure to use a new gasket, and apply a generous amount of transmission fluid to the gasket before installing it. Once the new valve body is in place, you’ll need to torque the bolts to the following specs:

-M6 bolts: 8-10 Nm
-M8 bolts: 15-18 Nm

After the new valve body is installed, be sure to check for any leaks. If there are no leaks, you’re ready to reinstall the transmission and test it out.

What Are The Torque Specs For The 4l80e Valve Body Bolts?

There are no torque specs for the 4l80e valve body bolts.

If you’re working on a 4l80e transmission, you’ll need to know the torque specs for the valve body bolts. These bolts hold the valve body in place, and they need to be tight enough to keep the valve body from moving around.

The torque specs for the 4l80e valve body bolts are:

-Tighten the bolts to 18 ft-lbs in a cross pattern
-Tighten the bolts to 40 ft-lbs in a cross pattern
-Tighten the bolts to 60 ft-lbs in a cross pattern

For example, if you’re working on a 4l80e transmission that has 18 bolts holding the valve body in place, you would start by tightening all of the bolts to 18 ft-lbs in a cross pattern. Then, you would move on to tightening the bolts to 40 ft-lbs in a cross pattern. Finally, you would tighten the bolts to 60 ft-lbs in a cross pattern.

Using the proper torque specs is important when working on a 4l80e transmission. If the bolts are too loose, the valve body could move around and cause damage to the transmission. If the bolts are too tight, the bolts could break and cause damage to the transmission. Either way, it’s important to use the proper torque specs when working on a 4l80e transmission.

What Are The Torque Specs For The 4l80e Valve Body Gasket?

There are no torque specs for the 4l80e valve body gasket.
The 4l80e valve body gasket is a very important gasket in your transmission. It helps to keep the transmission fluid in and the contaminants out. If this gasket were to fail, it would cause a very messy transmission fluid leak. The torque specs for this gasket are very important to follow. If you do not follow the torque specs, you could end up stripping the threads on the gasket or not sealing it properly. This could cause your transmission to fail.

The torque specs for the 4l80e valve body gasket are:

M8 bolts: 18-22 Nm

M10 bolts: 34-39 Nm

Make sure to use a torque wrench when installing this gasket. Do not overtighten the bolts as this could damage the gasket. Follow the torque specs carefully and you should have no problems installing this gasket.

What Are The Torque Specs For The 4l80e Valve Body Check Balls?

There are eleven check balls in the 4l80e valve body- six are 3/8″ and five are 5/16″.
If you’re working on a 4l80e transmission, you’ll need to know the torque specs for the valve body check balls. This is a simple process that can be done at home with a few tools.

First, you’ll need a torque wrench and a socket that fits the check balls. The torque spec for the check balls is 10-15 ft/lbs.

Next, you’ll need to remove the valve body. There are four bolts that hold the valve body to the transmission. Remove these bolts and set the valve body aside.

Now, you’ll see the check balls. There are two different sizes of check balls, so make sure you use the correct socket for each size.

Using the torque wrench, tighten each check ball to the specified torque.

Reinstall the valve body and you’re done!

This process is simple and only takes a few minutes. By doing this yourself, you can save time and money.

What Are The Torque Specs For The 4l80e Valve Body Springs?

The torque specs for the 4l80e valve body springs are 15 in-lbs.
When it comes to torque specifications, it is always best to consult your vehicle’s owner’s manual or a professional mechanic. With that said, the torque specs for the 4l80e valve body springs is 40 in-lbs. For a real life example, let’s say you are trying to install new valve body springs in your 4l80e transmission. You would first need to remove the old springs, which you can do by using a spring compressor tool. Once the old springs are out, you would then take your new springs and insert them into the transmission. To secure the new springs in place, you would need to apply 40 in-lbs of torque.
