Overview

The Speedfactory SF-Modified Shift Change Holder Assembly (SCHA) is a heavy-duty upgrade for B-Series FWD hydraulic transmissions, suitable for both dogbox and synchronized gearboxes. It features a CNC-machined, heat-treated tool steel arm to replace the stock component, enhancing shifting reliability and preventing damage to expensive transmission parts like dogs and syncro teeth. This assembly is designed to eliminate common mis-shift issues, such as 1-2-1 or 2-3-2, and provides smoother, more consistent shifts.

The base of the SCHA is TIG welded and braced for increased strength and fatigue resistance, while the interlock is also braced to prevent bending. Buyers can choose between an HD spring for a more authoritative return to center and improved 2-3 shifts, or a stock spring option for a more familiar feel.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
