Full Description
Q: What is the 3R-3-6081X and how does it differ from the 2-3-6081X?
A: The "3R" prefix indicates inside snap-ring retention, while the "2-3" prefix on the 2-3-6081X indicates outside snap-ring retention. Spline spec (26/27 x 1.176"), hub diameter (1.500"), and general application (GM TH350 family) are the same, but the retention groove location is different. Verify your output shaft retention style before ordering -- a mismatch means no axial retention on the yoke.
Q: What does "Full Spline" mean?
A: "Full Spline" means the spline engagement runs the full length of the hub bore -- there are no partial-spline lead-in sections that reduce engagement length. Full-spline designs provide more tooth engagement area and better torque distribution across the interface compared to partial-spline versions.
Q: Which GM transmissions use the 3R-3-6081X?
A: The 26/27-spline, 1.176" PD interface was standard on TH350, TH700R4, T56, and related GM transmissions across several decades. Cross-reference GM part number 7812557 for OEM confirmation. This transmission yoke is the inside-snap-ring replacement for all of these when the output shaft uses the 3R retention style.
