Gearbox - Peugeot 307 - 20CN20
GPA specializes in selling warrantied used gearboxes online, so please follow the few recommendations hereafter upon receiving and replacing your gearbox.
Make sure the gearbox we delivered matches with the defective one. If you do so before the installation, you might avoid some serious difficulties.
Our gearboxes are often delivered with peripheral parts provided for free (sensors, clutch release bearing, control unit, motors, etc.) which are not under warranty.
The 24 months warranty for this gearbox covers only the “naked” part.
To avoid damaging our gearbox, please start by finding the cause of the failure that resulted in your gearbox to break and solve it, so it doesn’t repeat.
Most of the openings of our gearboxes are sealed with plastic plugs. Make sure to remove them upon assembly.
Make sure every bolt and nut are tightened to the torque recommended by manufacturer, and keep in mind that some are not reusable.
The clutch guide tube and lip seals must be replaced by new ones. Always use a gear oil respecting the recommendations of manufacturer.
We advise you to take the opportunity and replace the clutch kit with a new one while your gearbox is disassembled.
Once your GPA gearbox is fitted, and before starting up the engine, make sure your check the oil level, that the bolts and nuts have been tightened using a torque wrench and that the gears shift well.
