FAG SR3913 Automatic Transmission Output Shaft Repair Sleeve - Rear, Rear Outer or Right

Automatic Transmission Output Shaft Repair Sleeve

The FAG SR3913 repair sleeve restores a worn or damaged transmission shaft sealing surface without removing the shaft or machining the part. Made from heat-treated stainless steel, it provides a precise sealing surface that helps extend shaft life and reduce premature wear.

Use this output shaft repair sleeve for transmission hardware repairs on applications such as Chevrolet Camaro, Corvette, Silverado, Tahoe, GMC Sierra, and Cadillac Escalade models where the shaft surface has been scored or worn.

• Precision repair sleeve for automatic transmission output shaft sealing surfaces
• Heat-treated stainless steel construction for durability
• Helps improve sealing on damaged shafts
• No shaft removal or machining required for installation
• Cost-effective repair solution for worn transmission surfaces
• Part number: SR3913

Detailed Product Overview

The FAG SR3913 is a transmission output shaft repair sleeve engineered to add a new sealing surface over damaged shaft areas. Its stainless steel construction is heat treated for strength and wear resistance, making it a practical solution when the original shaft surface has been compromised. This repair sleeve is commonly selected for fitments across Chevrolet Camaro, Corvette, Silverado 1500, Tahoe, GMC Sierra 1500, and Cadillac Escalade applications, as well as other listed vehicles from 1989-2019.

This part cross-references National 99215 for the same application. The SR3913 also cross-references 4133913100 and KWK99215.

What It Helps Repair

• Transmission fluid seepage caused by a worn output shaft sealing surface
• Grooves or scoring on the shaft where the seal rides
• Premature seal wear from surface damage
• Costly shaft replacement when the shaft can still be repaired
• Downtime from machining-based repair procedures

Installation Notes and Tips

Install the sleeve over the damaged shaft area and position it to cover the worn sealing surface. Because no shaft removal or machining is required, the repair process is faster than a full shaft replacement or machine-shop repair. Verify shaft diameter and installation depth before installation: shaft diameter 2.165 in (54.991 mm), flange diameter 2.441 in (62.001 mm), width on shaft 0.787 in (19.99 mm), width 0.905 in (22.987 mm), and installation depth 1.25 in (31.75 mm).

Confirm vehicle-specific fitment by year, make, model, and position before ordering. This part is listed for positions including N/A, Rear Outer, Right, and Rear across the supported applications.

Quality Assurance

FAG is known for precision bearing and sealing components, and this repair sleeve follows that engineering approach with a stainless steel, heat-treated design built for sealing repair work. Part number SR3913 is specified for direct-fit applications listed in the fitment data.
