They also come with a larger 300mm torque converter, much thicker than what was previously installed on older 4L60Es.
The latest versions of the 4L60E are built with the modern LS GM engine family in mind, which was introduced in 1998 more than five years after the introduction of the 4L60E. Take someone experienced, and the 4L60E can easily become the ideal starting transmission to work on a Chevy drag racer.Ĭhoosing the right 4L60E is the most important bit.

Its main advantage above other transmissions includes the inclusion of digital interfacing and control over the 700R4’s TV cable (which was often a fault rather than an advantage of any kind), and the fact that it’s generally cheaper at stock than a 4L80E or lower, yet still more than enough for any competent transmission expert to turn into a performance-friendly powerhouse. The 4L60E transmission remains a common choice for many Chevy enthusiasts looking for a stock transmission to begin with when working on a performance-friendly car.
It began as the non-electronic 4L60, installed in most GM trucks (like the Pontiac) before the introduction of the 4L60E, and other transmissions include its successors the 4L65E and 4L70E for large heavy-duty trucks, and stronger transmissions built with different gear ratios for even larger vehicles, such as the 4L80E. Yet the 4L60E isn’t the only transmission of its kind produced by GM at the time. The 4L60E is an automatic transmission with electronic control (E), 4 forward gears (and 1 reverse), longitudinal rear-wheel drive, and a 6,000 lbs. While there’s nothing wrong with refurbishing a classic muscle car with a new and improved Turbo 350, you’re more likely going to see cars from the 90s and beyond outfitted with the more modern set of 4L60s and 4L60Es – four-speed automatic transmissions that are basically descendants of the Turbo-Hydramatic 700R4, a powerhouse of a transmission.
Do we need speed? Power? Efficiency? Weight? Cost-effectiveness? Throughout the decades, automobile companies have come up with increasingly fine-tuned and advanced examples of this, working off older concepts and introducing new ones along the way, such as electronic control and fine-tuning.īut when it comes to matching cost with performance on a Chevy, you can’t go wrong with an older, customized transmission. A transmission is built to prioritize – and there are plenty of things to prioritize. Transmissions ultimately determine how the output of an engine’s power is translated throughout the rest of the vehicle. When adjusted with proper gear ratios and a set of the right aftermarket parts, the 4L60E can be just the high performance transmission you’re looking for.
