4L80E Output Speed Sensor Reluctor fits GM

Stellar Automotive Group 4L80E Output Speed Sensor Reluctor (On Rear Planet) – Compatible for GM 1991-Up

Restore accurate output speed readings in your 4L80E or 4L85E with this high-quality reluctor wheel from Stellar Automotive Group.

This reluctor mounts on the rear planet carrier and provides the speed signal to the transmission control module (TCM). The factory reluctor can wear, crack, or lose teeth over time, causing inaccurate speed readings — resulting in delayed shifts, harsh engagement, no upshifts, or P0500/P0722 codes. This upgraded steel reluctor restores accurate signal output, delivers smooth and precise shifting, and prevents costly TCM or wiring issues in these heavy-duty transmissions.

Perfect fit for popular models including:

• Chevrolet/GMC Silverado/Sierra 2500HD/3500HD (1997-up)

• Suburban/Yukon XL (1997-up)

• Express/Savana vans (1997-up)

• Cadillac Escalade (1999-up) — all with 4L80E/4L85E
• All 4L80E & 4L85E applications (1991-Current)

Common Problems This Fixes:

• Erratic or harsh shifting
• Transmission stuck in limp mode
• P0500 (VSS) or P0722 (ISS) codes
• Delayed upshifts or no 3rd/4th gear

Easy installation – remove rear planet carrier, replace reluctor, reassemble. Professional installation recommended for best results.
