However, it soon found its way into cars such as the Aston Martin DB7, V12 Vanquish, Ford Cobra, and Cobra R. Moreover, in 1992, GM engineered the T56 for use in the Dodge Viper and other Generation II motors. Its strength, simplicity, availability, and aftermarket support make it the perfect solution for those looking for a six-speed manual transmission. For the most part, a Generation III LS motor works best with GM’s T56 manual transmission. On the other hand, for some enthusiasts, automatic transmissions are a compromise not worth accepting.

However, mixing and matching Transmission Control Modules and Engine Control Modules, can quickly make things confusing. However, although these transmissions have their benefits, the addition of electronics adds an extra step during a transmission swap.Īn example solution for a 4L60E or 4L80E transmission swap is to use the factory ECU and harness, motor, and transmission to simplify installation.

And, with the addition of an overdrive gear plus electronics the 4L80E is both more fuel-efficient and easier to tune. Sharing the same gear set as the TH400 ensures top performance. And, like the 4L60E, the 4L80E is a continuation of a legacy transmission-the TH400. That's why the 4L80E is the perfect middle ground for enthusiasts. At the same time, it's intended for use in heavy-duty applications that require something more substantial than the 700R4 or 4L60. It's a great alternative to bulky solutions such as an Allision transmission. 4L80EĪlternatively, those looking for a more robust bolt-on automatic transmission for GMs generation III V8 motors are not without options.

Also, as an aftermarket part, the 4L60E transmission is a popular automatic transmission for Generation III LS motors like the LS1. Because the cost of a performance 4l60E transmission is significantly lower, it makes sense for enthusiasts to stick with this time-tested transmission. Unfortunately for the enthusiast, neither of these transmission is worth the premium price tag. Subsequent updates in 2001 led to the 4L65E, which featured strengthen planetary gears, clutches, input shaft, and a deeper pan giving it a maximum torque rating of 380 ft lbs.Īfter that, updates to the 4L65E led to the 4L70. It was capable of handling around 360 ft lbs. Offered between 19, the 4L60E proved reliable for those making close to factory power. As a result, it became a popular choice despite sharing most of its internal components with its predecessor, the 700R4.
