What This Part Helps Address

During a transmission rebuild, damaged, scored, worn, or incorrectly matched pump rotor components can contribute to pump-efficiency and hydraulic-pressure concerns. Depending on the condition of the transmission, these concerns may be associated with delayed engagement, harsh shifts, inconsistent shift quality, or other transmission performance issues.

This rotor kit is intended for qualified transmission repair and rebuilding. Inspect the pump body, slide, vanes, guide components, seals, and related pump parts carefully before assembly.

Please Note

This is a pump rotor kit without a slide. The pump slide is not included. Reuse the existing slide only if it passes inspection, or purchase the correct replacement slide separately.

For a complete transmission service, refill with the proper specified ATF and consider Lubegard ATF Protectant to help support smoother shifts and long-term transmission operation.
