Why this part
A worn governor bore bleeds pressure and turns crisp shifts into guesswork. Sonnax sleeves are machined to tighter tolerances than the original bore, restoring hydraulic integrity without pulling the whole valve body. At $40, it's the repair that makes sense before you spend ten times that chasing a transmission problem that was never going away on its own.
