Description
6-3-2671KX slip yoke, 1710 series, 16 splines at 2.500″ bore diameter, 9.594″ center-to-end. Direct replacement for transmission output shaft interface.
Full Description
Driveline clunk, vibration at a specific speed, and unexplained transmission fluid leaks share a common culprit: a worn slip yoke. The 6-3-2671KX delivers a ready-to-install 1710 series replacement with 16 splines at 2.500" diameter, purpose-built to solve these symptoms and restore smooth, quiet driveshaft operation.
Diagnosing Slip Yoke Failure
A healthy slip yoke moves smoothly on the output shaft with minimal radial play and no perceptible spline backlash. When the splines wear, the yoke develops side-to-side movement that creates the characteristic low-frequency thud heard during tip-in acceleration. Simultaneously, the scored sliding surface begins to damage the transmission seal, eventually producing a fluid trail on the driveshaft. Replacing the 6-3-2671KX at the first sign of spline wear prevents cascading damage to the seal and output shaft.

Confirming the Right Part
The 16-spline, 2.500" bore is the critical match criterion for your transmission. Count the splines on your output shaft, then measure pitch diameter with a micrometer or vernier caliper across the pitch circle. If the numbers match 16 and 2.500", the 6-3-2671KX is your correct replacement.
Replacement Procedure Summary
- Mark the rear driveshaft orientation at the differential companion flange
- Slide the driveshaft rearward to disengage the slip yoke from the transmission
- Replace the transmission extension housing seal while you have access
- Slide new 6-3-2671KX onto output shaft -- feel for full spline engagement
- Reconnect rear of driveshaft in marked orientation
- Top off transmission fluid; road test and confirm no leaks
