Can I use 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 4×4.
Does a 4L80E have a neutral safety switch?
The GM 4L60E and 4L80E series of transmissions have been extremely popular transmissions due to their wide availability and access to performance upgrades. This also makes them one of the easiest to add a proper neutral safety switch (NSS).
What do I need for a 4L80E swap?
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.
How much HP does a 4L80E have?
In short, Performance Automatic yields a 4L80E engineered to handle 700+ horsepower and comparable torque.
How much power will a 4L80E hold?
How much power can the 4L80E handle? A totally stock unit or rebuild will typically live well with up to 450 flywheel HP/TQ.
Will a 4L60E wiring harness work with a 4L80E?
This MRK GM 4L60e to 4L80e Transmission Conversion Harness kit allows you to convert your existing 4l60e transmission to a 4l80e transmission.

How much HP can stock 4L80E handle?
Is a 4L80 stronger than a TH400?
Though 4L80E race transmissions are quite similar to TH400 in terms of strength and parts used, however, there are differences, such as the added overdrive gear, advanced electronic controls, and a lock-up torque converter. 4L80E transmissions have nearly 25% overdrive and are 4 inches longer than the TH400.
What does the E stand for in 4L80E?
electronically controlled transmission
The term 4L80E denotes 4-Speed (4), Longitudinally mounted (L), 8000 lbs. vehicle weights for (80), and electronically controlled transmission (E). The ‘E’ means it requires an Electronic Control Unit (ECU) for control and firmness to enable its functionality.
Is 4L80 better than TH400?
The 4L80E is just a longer, heavier, overdrive version of the TH-400. It uses the same first three gear ratios but adds a 0.75:1 overdrive. This means that with a 3.55:1 rear gear, the overdrive drops the effective rear gear ratio to 2.66:1. This makes the first question more about torque converter selection.
