What moves transmissions & drivetrain prices
Transmission and engine prices depend on whether the unit is remanufactured, rebuilt, used low-mileage or a core, and on the exact application code stamped on the case. A remanufactured unit with a warranty is the top of the range; a used unit with unknown mileage sits at the bottom. Freight is often not included in the listing price and can add several hundred dollars. Core charges apply to many remanufactured units.
How to read this
The median is the middle asking price of live Buy It Now listings for this exact search, so it reflects what sellers are asking today, not what buyers paid last month. Use the 25th percentile as a realistic quick-sale price and the 75th as a patient-seller price. Anything listed well under the 25th percentile is worth checking for condition, completeness, and seller feedback before you buy.
