Let’s be real, electronic overdrive transmissions are the way to go. Between the improved fuel economy and turning less rpm at speed, it’s easy to see how they’re becoming increasingly popular. And for those of you who want to take full advantage of them, the manufacturers listed below offer stand-alone controllers, allowing you to modify a number of parameters to suit your driving style. Whether it’s a 4L60E, 4L65E, 4L70E, 4L80E, 4L85E, 5L40E, or a 5L50E, these controllers give you the ability to adjust everything from shift firmness to shift points, including a full manual mode for paddle-style shifters.
