The genuine GM speed sensor that fits both the input and output positions on a 4L60E, 4L65E, 4L70E or 4L80E. If your truck threw a P0716, P0717, P0722 or P0723 and started slamming shifts, this is usually the part that fixes it. Comes with the seal, part number 24203876.
When a GM automatic starts shifting hard, banging into gear, or dropping the speedometer, the transmission speed sensor is the first thing an experienced tech checks. This is the real GM Genuine Parts unit, number 24203876, the same sensor GM installs and validates as Original Equipment. It has also been sold over the years under the ACDelco OE label, so if a listing shows one number or the other, it is the same part.
What makes this one handy is that it fits both the input speed sensor and the output speed sensor locations, so you can replace both at once and clear the whole set of speed related codes in a single job. It covers the 4L60E, 4L65E and 4L70E, and it is a proven fit on the 4L80E as well, across Chevrolet, GMC, Buick and Cadillac trucks, vans and SUVs. The seal is included, which matters, because reusing an old hardened seal is how you end up with a fresh leak right after the repair.
Installation is about as simple as transmission work gets: unplug the connector, pull the old sensor, drop the new one in with the supplied seal, and torque the hold down bolt. Most people are in and out in a few minutes, reset the computer, and the hard shift is gone. If you are chasing a P0716, P0717, P0722 or P0723, start here before you tear anything apart.
