Beginning in the late 90s and the early 2000s, GM began to phase in a new variant on the 4L60E, the 4L65E. This transmission introduced a new set of 5-pinion planetary gears as well as a newly improved and stronger output shaft. This video breaks down how to transform a 4L60E, 4L65E or 4L70E into a top-tier performance transmission with Sonnax Level 3 build components. Many parts also are found in Sonnax heavy-duty and Level 1 and Level 2 performance builds, so no matter what power level you're running at, it's a great way to understand the options when upgrading 4L60.

Introduced in 1993 for trucks, vans, and SUVs, then in 1994 for rear-wheel-drive passenger cars, the 4L60E from General Motors is an evolution of the Turbo-Hydramatic 700R4 and replaced the tried and true TH350. Advantages over the TH350 include lower gear ratios, improved valve body, the addition of 4th gear (overdrive), and a lockup torque converter. Popular choice for street performance and retro fitting. They are readily available on the used market and can handle 400-700 HP, depending on year and internal modifications.

Important Years

1995

• Received a pulse width modulated torque converter clutch solenoid

1996 received the most significant updates, including..

• Began receiving a bolt-on bellhousing in certain models (all models by 1998)
• Six-bolt tail shaft
• Modified 3-2 downshift solenoid

Important Note:
1996 and newer 4L60Es are not interchangeable with previous models due to these upgrades

2001

• Name designation changed to 4L65E
• Torque capacity increased as a result of the four pinion planetary carrier being replaced by a five pinion unit
• Better 3-4 clutch
• Improved input shaft
• Deeper pan for more fluid

Due to these improvements and added strength, the 2001 and later 4L65E is the most desirable for performance applications.

In case you don’t know about the 4L60E transmission, it was seen in the majority of the General Motors rear-wheel drive vehicles which is about 20 years now.

The question is, are 4L60E transmissions all the same? And the answer is a simple no. you must also note that, not all 4L60E transmissions are compatible with each other.

Later I will show you some of the big differences between 4l60e vs 4l65e which will help you better to understand and identify each when it comes to 4l60e vs 4l65e identification.

My advice here is, you shouldn’t change your 4L60E with any random 4L60E. This can cause you a lot of headaches along the line. Also, read this article What Are 4l60e Transmission Fluid Capacity

Are all 4l60e transmissions interchangeable?

If you are wondering if all 4l60e transmissions are interchangeable, I will No.

Not all 4I60e transmissions are interchangeable and that is because the output for 2WD and 4WD are not the same and likewise the input shafts for a 298mm and 300mm 4I60e units.

So basically, not all 4L60E transmissions are compatible with one another.

How can you tell the difference between a 4l60e and a 4l65e?

Strength is one-word I can use to answer the question, how can you tell the difference between a 4l60e and a 4l65e?

This 4L65E transmission was produced to handle more torque than 4l60e or any other transmission in the market.

Although their case is identical, the 4L60E later became the 4L65E when General Motors upgraded some key internal parts of the model.

You don't need waste all your time figuring out which brand to buy, the best brands handpicked for you.

So if you are searching to get an older 4L60E that is up to the 4L65E’s specifications, then you will find it.

Best os apps. They multiplied the transmission torque capacity to about 380-foot pounds. Please note that this change happened in 2001.

This 4L65E transmission was developed with the LS V8 engines in mind. Though they are not compatible directly with the 4L60E due to they make use of various torque converter and input shaft.

And the input shaft is about 300mm vs. 298mm on the 4L60E transmission.

This means if you are using a 4L65E, ensure you take the 300mm torque converter with it.

But if you don’t get this converter, then no that they are not interchangeable.

Can I replace my 4l60e with a 4l65e?

If you are wondering whether you can replace your 4l60e with a 4l65e in your vehicle, well the answer is yes and you will need a 4l60e to 4l65e swap kit to do this. Changing from the 4L60E to the 4l65e is not too difficult to do in a vehicle that was equipped with both transmissions.

But you should know that it won’t be an easy swap to do, and moreover, the 4L60E can actually handle a lot of power on its own.

Note that the 4L60E transmission is an automated shift, and also a four-speed overdrive transmission which is well known to be one of the best-automated transmissions ever produced.

Remember that before the 4L60E transmission was manufactured, there was another transmission known as the Turbo 700R4.

However, 4L60E has an impressive strength, and it can be used in both trucks and cars.

What transmission can replace a 4l60e?

it is possible to replace the 4L60E, as 4L65-E can directly replace a 300mm TC version of the 4L60-E. Note that all 4L65-E transmissions are produced with the bell housing, TC, and input shaft for all Gen-III/IV engines.

Torrent engine torrent. So if it’s a 4L65-E you really want, then the only thing that will stand against you is the cost.

What years does 4l60e transmission fit?

Note that the older 4L60-E transmission has a 3 piece case of casted aluminum alloy;

1. The bell housing
2. The main case
3. The tail housing.

However, General Motors shortened the package to about 21.9 inches long which is equivalent to a manual transmission of about 15.4 inches.

This transmission input shaft has about 30 splines. It typically comes with a pinned flare and O-ring fittings on the passenger side which cools the circuit. Also, it has a square oil pan.

The six-bolt hex rear output is key differences of the Later 4L60-E (1996-2010) from the Early 4L60-E (1992-1997), and tail housing/adapter pattern is another 4L60 (1990-1992), from the 700R4 (1982-1989).

Their former versions come with a four-bolt square bolt pattern on the adapter or tail housing. Also, the removable bell housing is also another exceptional feature.

The two-wheel-drive model has tail housings and normally a long output shafts than the four-wheel-drive model, which has a different adapter put together and a shorter output shaft.

4l60e transmission identification

Here is the 4l60e transmission identification you need to know:

1. Comes with four bolts connected to the tail shaft (or transfer case) to the transmission.
2. Another thing is the vehicle speed sensor which locations were changed during the production.
3. It comes with an info sticker on top of the bell housing on top of the transmission.

Below are what you should know about each of the transmissions.

4l65e Transmission Fluid

• Their Dimensions: This 4L65E transmission comes with the same case dimensions and size as the 4L60E. Although they also bolt their cross member in the same exact spot.
• Their Wiring: The current vehicles in the market can be a little difficult to deal with than older models. Please always remember that you need to ensure that any component you intend to install should be compatible with the one you want to replace. Remember that the LS series engines have both their transmissions and engines controlled by their ECM. So in case, you swap a component for another year or size, note that you must reprogram the ECM.
• Their Gearing: Both of the transmissions are geared exactly the same way. Both of them are overdrive transmission with a final drive of about .70 to 1
