Requires a transmission output shaft with 32 splines and NO o-ring. If your TH-400 or 4L80 has an o-ring on the output shaft, you need a short-barrel counterbored slip yoke instead. Spline count includes a blind spot (one or two missing internal splines) that does not affect fit.

It slides onto the transmission output shaft and connects to a 3R universal joint, allowing the driveshaft to change length as the suspension moves. This full-spline, non-vented yoke includes a dampener and uses an inside snap-ring style. It is commonly replaced when the original yoke is worn, splines are damaged, or a driveline upgrade is performed on transmissions like the 6L50, 6L80E, TH-400 (without o-ring), or 4L80 (without o-ring).
