GM GENUINE PARTS Automatic Transmission Clutch Kit 24259848 — 1-2-3-4 & 3-5‑R OE-quality replacement

GM Genuine Parts 24259848 is an OE-quality automatic transmission clutch kit covering the 1-2-3-4 and 3-5-Reverse clutch assemblies for compatible GM transmissions.

This clutch kit is engineered and tested to General Motors specifications to replace the original factory components in compatible GM vehicles. Built in the United States and backed by GM, the kit delivers the fit, materials, and dimensions designed for the same form and function as the parts installed at the factory. It’s intended for technicians and do-it-yourselfers who need a direct-replacement clutch pack to restore transmission shifting performance to OEM intent.

What exactly does this clutch kit replace and why does that matter?

This kit replaces the 1-2-3-4 clutch pack and the 3-5-Reverse clutch pack inside the specified automatic transmission. Replacing these clutch packs is essential when plates wear, lining materials degrade, or engagement becomes inconsistent.

• Includes friction plates and steel plates sized to GM OE specifications
• Fits the same bore and spline dimensions as factory parts
• Restores clutch engagement timing and torque transfer consistency
• Manufactured and validated to GM quality standards

How does GM Genuine Parts quality differ from aftermarket alternatives?

GM Genuine Parts are created or validated by General Motors to match the original components used on assembly lines. That guarantees dimensional tolerances, materials, and performance characteristics intended for the vehicle’s transmission design.

• Engineered to the OEM drawing and material specifications
• Tested for fit and function within GM vehicle applications
• Backed by GM for compatibility and traceability of origin

What should a technician check when installing this clutch kit?

Proper installation requires inspection of the clutch drum, piston, snap rings, and bore for wear or damage. Small deviations in mating surfaces or worn components can cause rapid re-failure even with new clutches.

• Measure drum and bore tolerances for out-of-round or scoring
• Inspect pistons, seals, and snap rings for correct clearance
• Replace any worn hubs, bushings, or valve body components as needed
• Use GM-recommended lubricant and follow torque and assembly specs

When should you choose this kit over a rebuild or remanufactured transmission?

If diagnostics isolate slipping, delayed engagement, or inconsistent shift feel to worn clutch packs, replacing these specific packs is a targeted, cost-effective repair. A full rebuild or reman may be required if there are broader internal failures.

• Ideal for clutch-plate wear without catastrophic housing or gear damage
• Saves cost and time when valve body and pump are serviceable
• Provides OEM-fit replacement for focused clutch pack repairs

Who is this for: This GM Genuine Parts 24259848 clutch kit is for professional technicians, transmission specialists, and informed DIYers working on compatible GM automatic transmissions who want the security of OEM-validated parts. Choose this kit when you need factory-fit friction and steel plates to restore the intended shift performance and longevity of the transmission.
