Identify the used gearbox
Choosing a used gearbox starts with the code on the original unit. The brand, model and engine capacity help with a search but are not enough on their own. Gear ratios, mountings and control systems can differ within the same vehicle range. Photograph the transmission label or engraving and confirm its reference with your workshop.
Manual or automatic: confirm the configuration
Check the transmission type, engine code and drivetrain configuration. Compare driveshaft outputs, mounting points and electrical connections. For automatic units, ask whether the torque converter, control unit or other accessories are included. These details should appear in the description; do not infer their inclusion from photographs alone.
Condition and installation preparation
Read the listed condition and examine the housing, plugs and brackets in the photographs. An external inspection does not establish the internal condition of a transmission. Confirm what documented information or test results are available for that particular unit. Your workshop should specify the correct fluid, required consumables and any vehicle-specific adaptation procedures.
A final checklist to avoid mistakes
Before ordering the used gearbox, check the full reference, vehicle configuration and included components. Verify the listed price and review delivery and return terms. Keep the original component details available to resolve questions. Installation should be carried out by a qualified professional following the applicable technical documentation.
