Quick answer

SERVICE BULLETIN M1611: MILWAUKEE-EIGHT TRANSMISSION SHIFT DRUM UPDATE. PURPOSE: This bulletin informs dealers of a transmission shift drum running change to all variants of the Milwaukee-Eight powertrain. Starting on October 4, 2023 all Milwaukee-Eight CVO, Police, Softail, Touring and Trike models will be assembled using a common shift drum. The new shift drum (Part No. 33900265) is replacing the old shift drum (Part No. 33900172). The new shift drum was developed to include the "D" shaft on the end to interface with the Gear Position Sensor on 2023 CVO Street Glide (FLHXSE) and Road Glide (FLTRXSE). For all other Milwaukee-Eight models, the bearing door has been modified by adding a pocket to accept the "D" shaft of the new shift drum.

What this bulletin may mean before buying

Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
