Detailed Description

TC Remanufacturing SU13 is an automatic transmission torque converter specified for 1999 Subaru Impreza and 1999 Subaru Legacy vehicles. The converter uses a lock-up design, which supports efficient drivetrain coupling during highway cruising, while the low stall calibration helps match the transmission behavior expected for these Subaru applications. Its 11.250-inch diameter, 11.750-inch bolt circle, slotted hub, 4-pad mounting, and 22-spline configuration are important identifiers when matching the correct replacement unit. The integrated 115-tooth ring gear and listed converter code, Orange Paint, provide additional identification for service verification. If you are sourcing a 1999 Subaru Impreza torque converter or a 1999 Subaru Legacy automatic transmission torque converter, SU13 is the part number to confirm.

What This Part Helps Address

• Torque converter shudder or inconsistent lock-up operation
• Slipping or delayed drivetrain engagement related to converter wear
• Incorrect replacement selection when diameter, spline count, or pilot dimensions do not match
• Transmission service needs on 1999 Subaru Impreza and 1999 Subaru Legacy automatic models
• Noise or drivability concerns tied to a worn or mismatched converter assembly

Installation Notes and Tips

Verify the converter code, spline count, pilot diameter, pilot length, and ring gear tooth count before installation. Confirm transmission compatibility against the vehicle’s original unit and inspect the flexplate, pump engagement surfaces, and related transmission components during replacement. Proper alignment during installation is important to avoid pump damage and ensure correct converter seating. Part number SU13 should be matched to the listed Subaru applications before final assembly.

Quality Assurance

TC Remanufacturing supplies remanufactured transmission components for service replacement use. This torque converter is identified by the listed OE-style dimensions and application data for 1999 Subaru Impreza and 1999 Subaru Legacy models. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
