How do I know what stall converter I have?

The only way to know the true stall speed of a converter is with a transbrake however a flash stall can give a rough idea of what it is. From a dead stop, mash the throttle and watch the tach. The tach will jump up to an rpm before the car really starts to move.

Are all 4L60E Bellhousings the same?

4L60E transmission bellhousings are not the same One of the main differences in the earlier and later 4L60E transmissions is the bellhousing area. In the later versions of it had a removable bellhousing. This makes it a bit easier to put behind an engine that it wasn’t originally intended for.

How do I know if my torque converter has a stall?

“Flash stall” is when you, from a dead stop, press the gas pedal to wide open throttle (wot). Watch your tach needle, you will see the needle jump to a certain rpm, that is “flash stall”. A drag racing-style trans brake will give you closer to the true stall speed of a torque converter.

What does a shift kit do for a 4L60E?

Adding a shift kit to your 4l60e equipped car, truck, or SUV will help correct and improve the lazy shifting that the 4l60e is somewhat known for in factory form. Properly installed shift kits will make all shifts more firm and quick without making it feel like you got hit by a train.

Does a 4L60E have a lock up torque converter?

Re: Explanation of gears 4L60E 3rd gear is 1:1 ratio and 4th gear is an over-drive ratio of . 67:1 if I recall correctly. It also has a lock-up torque converter (TCC) which is a separate function and engages in 3rd and 4th gears under light throttle.

What is the difference between a low stall and a high stall torque converter?

For many street trucks that are used for towing, daily driving, and performance, owners choose a lower-than-stock stall converter. While high-stall converters are the ticket for racing, they generate lots of heat due to high slip percentages and can create a huge rpm drop when lockup is engaged.

What is a 2500 stall converter?

A 2,500 stall speed doesn’t mean you need to rev the motor to 2,500 rpm for the vehicle to move.” What it does mean in this case is 2,500 rpm is the limit at which the converter will hold back the engine speed if transmission output is prohibited. Stall speed will be the maximum rpm shown on the tach.

Can I put a 4L80E in place of a 4L60E?

Swapping from the 4L60E to the 4L80E is not difficult to do in vehicles that were equipped with both transmissions. Here are the main parts that you are going to need in order to make your own 4L60E to 4L80E swap kit. It’s not the easiest swap to do, and a 4L60E can handle a lot of power on its own.

Can I put a 4L60E in place of a 4L60?

If you were to try to put a 4L60E where a 4L60 once was you’d have to buy an aftermarket transmission controller for it. On the other hand, a 4L60 would need a custom bracket to hook into the TV cable properly. They also don’t have the same geometry for engaging the torque converter, so you’d need adapters for that.

What’s the difference between a stall converter and a torque converter?

Stall speed is the speed at which the converter holds back or limits the engine speed if the transmission output is prohibited. When your torque converter prevents the power transfer from your engine to your transmission, it increases the engine’s RPM stalls.

How much horsepower can a 4L60E handle?

So, to keep things cooler they run a deep pan with a filter extension. The heavy-gauge cast-aluminum pan allows for an additional two quarts of transmission fluid, which enhances cooling under extreme conditions. 22. See, that’s all it takes to build a 4L60E trans that’s rated to handle over 1,000 horsepower.

When did the 4L60E transmission come out?

4L60E Transmission Specs. The 4L60E transmission was first introduced in 1992 as an upgrade or replacement to the 700R4 transmission, also known as the 4L60 transmission. The two transmissions were mostly similar, with a major difference being the upgrade from hydraulically to electronically controlled transmissions.

How much fluid does a GM 4L60E need?

The 4L60E transmission weighs 146 pounds dry, and 162 wet. It requires 8.4 quarts (9.64″ torque converter) or 11.4 quarts (11.81″ torque converter) of transmission fluid, Below is a list of common transmission problems with the GM 4L60E Transmission and possible solutions to repair.

What’s the difference between a 4L60E and a 96-99?

These have the classic 6 bolt bellhousing like the other classic transmissions that came before it. This version, as well as the 96-99 4L60E use a 298mm input shaft /torque converter. The major difference between the two-piece case 4L60E versions, is that the bellhousing bolts have slightly different patterns.

Can a 4L60E bellhousing be used on a Gen i engine?

The 4L60E bellhousing can bolt to either engine, although you may need an adapter to get a Gen III transmission to bolt to Gens I and II and vice versa. For the purposes of easy identification, we have broken the 4L60E into 4 distinct eras. These eras are easy to identify from the outside of the transmission.

When did the 4L60E series of transmissions come out?

1998- LS series of engines was introduced. 300mm torque converters and 30-spline input shafts were added. 1999- Many refinements to the transmission are made, until they start calling it 4L65E and 4L70E.

How much torque does a 4L60E small block have?

Beginning in 1998 a new 300mm torque converter with improved higher-capacity internals, 300mm style input shaft, and 300mm style pump was also introduced on models coupled to a Gen III Small Block. The 4L60E is rated to handle up to 360 ft·lbf (488 N·m) of torque.

What kind of input shaft does GM 4L60E use?

They also have different input shafts and torque converters. 4L60E’s uses a 298mm input shaft for non LS and a 300mm input shaft for LS applications. 4L65E/4L70E uses a 300mm input shaft and converter designed for LS applications only.
