Installation Notes and Tips

Confirm the transmission code, spline count, bolt circle, pilot diameter, and mounting style before installation. For best results, inspect the transmission fluid, cooler, and related hard parts during replacement, and verify that the 11.000-inch converter and 1630 RPM stall match the original application. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
