2. **Limited Availability and Long Lead Times**

Unlike mass-produced aftermarket parts, OEM gear motors may not be readily available in stock. Ordering from Mercedes-Benz or authorized dealers can result in **weeks or even months of wait time**, delaying repairs.

3. **Potential for Overkill**

If the gear motor fails due to a **transmission fluid issue, worn synchronizers, or a failing torque converter**, replacing only the gear motor may not address the root cause. A full transmission rebuild or replacement might still be necessary.
