Buying Guide for a Second-hand Gearbox

If you wish to save on costs while purchasing a gearbox, we guarantee a high-quality option at an affordable price. Additionally, we provide guidelines to help you choose the best transmission that perfectly suits your machine model. First, ensure that you check the mileage by running a verification analysis from the donor machine or ask for the records that show the year of purchase. Choose the newest model or one with low mileage as evidence of how much life is left in it. Do a thorough check for leaks that could cost you on repairs. You can check on the transmission fluid levels to see if there any signs of drips after a given time. Also, do a visual inspection for any signs of cracks or damage to the gearbox. Go ahead and ask for the transmission history to determine any risk factors. You can also scrutinize the automobile’s body for any signs of collision or lots of bodywork that indicates involvement in a fatal accident.
To determine the perfect gearbox model for your machine, you need to establish its service factor based on the daily application periods, and vibrations involved during application. It will be best if you ask for the warranty details and determine whether it covers both labor and parts to know if it suits your needs. Also, perform a test on a transmission bench to confirm if it shifts seamlessly on all gears. In case you don’t have sufficient know-how about used gearboxes, you can ask for assistance from one of our experts to ensure that you choose a perfect option.
