What is needed to swap a 4L60E to a 4L80E


What is needed to swap a 4L60E to a 4L80E?

In almost every case, you will need to build (or buy) a new transmission crossmember, a new torque converter, a set of transmission lines, a modified or swap harness, and a modified driveshaft with a larger yoke and crossover U-joint.

Will a 4L60E transfer case fit a 4L80E?

Swap your 4L60E transmission to the much stronger 4L80E transmission with our 4L60E to 4L80E adapter (adapter only). You can use the computer you have now on 1998 up models with the use of our #10X wiring harness. The transfer case you have now can be used as is and will be moved 1 3/4 to 3 1/2 inches to the rear.

Are all 4L60E plugs the same?

There are two different ECU connectors for the 4L60E. The green connector is from 1999-2005, while 2006… Chevy transmission, Ls engine, 4l60e transmission rebuild.

How do you wire a 4L80E?

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 4×4.

Can a 4L60E be used without a computer?

Externally, all it needs is a 12-volt source and an engine-vacuum reference. However, if your trans is, in fact, a 4L60E, running it off a computer is mandatory. On “E” transmissions, the computer controls everything: TCC lockup, gear changes, shift quality and firmness, and line pressure.

Will a 5.3 bolt up to a 4L80E?

Will A 4L80E Bolt Up To A Gen 5 Lt1? Our 4L80E Performance Transmission (up to 800 pounds of performance) work fine with all Gen 5 and 5/5 engines.

Is a 4L60E the same as a 4L80E?

The 4L60E and 4L80E have model numbers that are similar. However, these transmissions differ in the way they were manufactured. The 4L80E is an electronic overdrive successor to the Turbo 400, and the latter is a transmission that was used for drag racing and hot rodding applications.

What transfer case is behind 4L80E?

In addition to the Chevrolet 90 degree “Small Block” and “Big Block” patterned engines (image, left), the front face 4L60-E is natively compatible with the V6, V8 and I6 engines.

What year 4L60E are the same?

The key distinction of the Later 4L60-E (1996-2010) from the Early 4L60-E (1992-1997), 4L60 (1990-1992), or 700R4 (1982-1989) is the six-bolt “hex” rear output or tailhousing / adapter pattern. The previous versions featured a four-bolt square bolt pattern at the adapter or tailhousing.

Will a 4L80E bolt up to a 350?

The 4l80e will bolt up to your existing flywheel using 3 bolts instead of 6. The jury is still out on this one as the 4l80 came with 6 but 350 and 400 only ever used 3. I ran 3 in my turbo truck setup without issues. FYI, there were TH400 converters that DID come with 6 bolts.

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.

How do I know what year my 4L80E is?

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

What does a 4L80E need to work?

The 4L80E needs to have an electronically controlled speed sensor, for the 4L80E transmission controller to work properly. Mechanical speedometer tail-shaft conversions can be used in older vehicles.

What’s the difference between 4L60 and 4L60E?

The 4L60E is very similar to the 4L60 in almost every way, including having a 4-gear automatic shift transmission. Also, both 4L60 and 4L60E feature gears positioned or placed longitudinally (in a north-south direction). However, the 4L60E can handle a GVWR of 8,600 lb, which is more than 4L60’s.

Does a 4L60E have a kickdown cable?

It looks very much like the 700R4 that it replaced, but don’t be fooled. They are so close that the 700R4 was also known as a 4L60 after just a few minor changes. The 4L60E has no kickdown or TV cable, and all of that work is done through solenoids that are run thanks to a VSS at the back of the transmission.

How much power can a 4L60E handle?

Their Stage 2 Pro Race transmission can handle gobs of power while their Invincible Black Edition 4L60E trans can support over 1,000 ponies.

What causes a 4L60E transmission not to shift?

The 1-2 shift failure on the 4L60E is often due to a faulty throttle position sensor (TPS). Test the sensor (there should be a smooth, linear electrical response over the range of motion) or substitute a known good unit.

Will a 4L60E Flexplate work with a 4L80E?

4L60E to 4L80E conversion flexplate. This Flexplate works on all 98 up LS based engines with the exception of the LQ4 6.0. The LQ4 LS engine can be identified by the dished pistons. This new flexplate would be used when taking the 4L60E out and replacing it with the 4L80E.

Will a 4L80E bolt up to an LS?

Re: Can any 4l60 work with a 5.3? Most 5.3’s came with a 4l60e behind them, so YES, they fit. Look for one from the “LS years” meaning 2000 which will have all the correct bell housing bolt holes. You need to find a 2wd tranny as well, otherwise the tail shaft will have to be swapped out to work.

Which is better 4L60 or 4L80?

Without a doubt the 4L80E is the more powerful of the two transmissions. Vehicles with powerful engines, such as big trucks for towing or high speed cars for racing, require a 4L80E rather than a 4L60E as the power of the engine is likely to break smaller, less powerful transmissions.

Is there 2 different 4L60E transmissions?

The two transmissions cannot be differentiated from the outside. The 4L65E shares the same exterior parts but have stronger internals such as 5 pinion planets compared to 4 in the 4L60E. 4L60E uses a 6.5″ depth bell with 6 bolts for non gen 3 LS applications and a 7″ depth bell with 7 bolts for LS applications.

How many miles will a 4L80E last?

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

What transmission can replace a 4L60E?

However, if you use your truck hard, it can be a weak point that can fail-in some cases, repeatedly. The owner of this rig could’ve kept paying to have the 4L60E rebuilt, but instead chose to replace it with the much beefier 4L80E four-speed automatic transmission.

Whats the difference between a 4L60E and a 4L65E?

More pinion gears help to spread the load, allowing 4L65E transmissions to handle more torque than their 4L60E brethren. Additionally, a better 3-4 clutch, improved input shaft, and a deeper pan for more fluid were added.

Will a 2wd 4L60E work in a 4wd?

These are externally interchangeable. The 4wd version reduces NVH induced by the transfer case hanging way behind the trans mount. When I did my 4L80 swap, I started with a 2wd trans that I converted and rebuilt.

Will a 4L60E bolt up to a 454?

In the long run a 700R4/4L60 or 4L60E/4L65E/4L70E transmission will not hold up behind a big block, Or atleast not a good running one . You can build them to take power, Its the low-end grunt from a BBC & a heavy truck with big tires that WILL kill it.

Will a 6.2 bolt up to a 4L60E?

Registered. Yeah, it will bolt up fine, but you won’t be able to make it shift. The 4L60E was electronically controlled and if you don’t have the controller it won’t work.

Will a 4L60E bolt up to a 350?

Will A 4l60 Bolt Up To A 350? You will be able to bolt straight up to your 350 with the 4L60E. Yes, but you will need some sort of control over the tranny. As the OD is electronically controlled, the “E” at the end of the 4L60 is a sign of this.

Will a 4L80E bolt up to a SBC?

It will bolt up. But why have that super heavy trans behind a 283.

What transmission is best for a 454?

Does a 4L80E need both speed sensors?

Yep, NO front sensor is needed with our harness.

How many speed sensors does a 4L80E have?

The 4L80E transmission may feature two speed sensors, one for turbine input speed and one for output speed.

Can speed sensor cause shifting problems?

Transmission problems

One of the most common signs of a bad speed sensor is abnormal automatic transmission operation. If the VSS is faulty, the transmission may exhibit symptoms such as delayed shifts, hard shifts, and limited gear operation.

What is the difference between a 4L80E and a 4l85e?

The primary difference between the two is the 4L80-E planetary gear sets have four pinion gears as opposed to the 4L85-E gear sets that have five pinion gears.
