4l80e Transmission Speed Sensor


Jun 8, 2022

Where is the speed sensor on a 4L80E transmission?

How it's done: Sensor is located on the driver's side of the transmission immediately behind the bell-shaped portion of the housing. via

What sensors are on a 4L80E?

The 4L80E transmission may feature two speed sensors, one for turbine input speed and one for output speed. It uses the Input Speed Sensor to monitor input speeds to compare against engine speed and output Shaft Sensor speed, using this data to adjust shift speeds under instantly detectable conditions. via

How do you test a input speed sensor? (video)


How much HP can a 4L80E handle?

In short, Performance Automatic yields a 4L80E engineered to handle 700+ horsepower and comparable torque. via

What happens when transmission sensor goes out?

A failing transmission position sensor may no longer send the right signals to the Powertrain Control Module, or PCM. Without signals from the position sensor, the PCM will no longer know when to shift the transmission's gears out of park into a moving gear. Transmission shifts into the wrong gear. via

Can you run a 4L80E without a computer?

However, the 4L80E can be easily converted to a manually shifted valvebody, which eliminates the need for the computer and much of the electronics and wiring. This conversion turns the 4L80E into a great heavy-duty analog overdrive transmission that can be easily swapped into almost any high-horsepower 4x4. via

What is the difference between 4L80 and 4L80E?

Like the 4L60 and 4L80 transmission models, the 4L80E is a 4-speed longitudinally-mounted automatic-shift transmission. The E in 4L80E denotes that the transmission comes with a powertrain control system instead of the mechanically-controlled TH400. via

How long will a 4L80E last?

Registered. IMHO, the 6.5's and 4L80E's are capable of 500,000 miles... via

Can a 4L80E handle 1000hp?

Our PERFORMANCE 4L80E series is ideal for street/strip driving and upgrades from a 4L60E/4L65E platform. It's rated at 1000 RWHP.... via

What is the strongest GM transmission?

The 10L90E is by far the biggest and heaviest modern automatic transmission in GM history, but it's also the strongest and offers amazing performance and economy when matched with a Gen V LT engine. This is part of the newest technology in the performance world. via

Is a 4L80E a 6 speed?

These TCI 6x 6-speed GM 4L80E automatic transmission packages are the first aftermarket 6-speed automatic transmissions capable of handling 850 hp. They give you six forward gears (2.97, 2.31, 1.57, 1.18, 1.00, and 0.75) for quicker acceleration and increased fuel economy at cruising speeds. via

Will a speed sensor stop a car from starting?

In fact, most sensors are responsible for actually making the changes to critical systems such as ignition and fuel systems. Since any engine requires the correct air to fuel ratio and ignition timing to start, having a faulty sensor that can't adjust these symptoms on the fly can cause the engine to not start. via

What is the purpose of a speed sensor?

The speed sensor, an essential component for the operation of several on-board systems, allows the magnetic rotation speed to be measured in order to provide a voltage corresponding to the rotation speed. It is widely used in the aeronautics, automotive and precision engineering sectors. via

How much power does a 4L80E Rob?

How much power can the 4L80E handle? A totally stock unit or rebuild will typically live well with up to 450 flywheel HP/TQ. via

Which is better 6L80E vs 4L80E?

"Stock versus stock, the 4L80E and 6L80E are very similar in terms of strength," explains Kyle House of Circle D. "The main difference is that the 6L80E has much more versatile gear ratios. With a ridiculously low 4.03:1 First gear, it's a stump puller. via

Are 4L80E transmissions good?

Great transmissions? Though often overlooked, GM 4L80E automatic trans have had a reputation of being some of the best options on the market. The high-performance automatic transmission is known for its power and reliability. via

How much does it cost to rebuild a 4L80E transmission?

A local transmission shop will rebuild a 4L60E for around $900 to $1,200 and a 4L80E for $1,300 to $1,800, with used units going for about $400 and $600 to $1,000, respectively. via

Will a 5.3 bolt up to a 4L80E?

In order to mate the 5.3 to the 4L80 transmission, we needed PN 551356X, which is a PRW dished flexplate that is SFI 29.1 certified and includes the bolts. via

Are all 4L80E transmission the same?

4L80E Differences:

'91 -'96: They are all pretty much the same. They were also known to have a crappy connector that passes through the case. Most have had them updated by now, but there are still some that haven't and might need replacing. via

How many forward gears does a 4L80E have?

The 4L80-E (and similar 4L85-E) is a series of automatic transmissions from General Motors. Designed for longitudinal engine configurations, the series included 4 forward gears. It was the 4-speed electronically commanded evolution of the 3-speed Turbo-Hydramatic 400, first produced in October 1963. via

Does the 4L80E have overdrive?

The 4L80E is a truck automatic transmission that was introduced by GM in the early '90s. It basically uses many of the same internal components as the TH400 but has an overdrive Fourth gear and uses electronics to control shift points, firmness and that sort of thing. via
