Transmittance Pathway

The transfer case to transport power from the engine to the driveshaft is similar to a bicycle, which uses a chain on sprockets. The driving style can alter by swapping out the sprockets. The chains may stretch or break due to the extreme stress they are under.

The chain can come loose from the sprocket, resulting in a total loss of transmission function. If you notice any stuttering or hesitation when shifting gears, you may have a weak chain. A broken chain can fix by purchasing a new one.
