The GMC Jimmy Transfer Case sends engine power to both front and rear axles, giving the SUV true four wheel traction when road or trail conditions require. This unit, which bolts to the transmission, splits torque between the differentials through driveshafts. Part-time and full-time versions appeared across the model years. The Transfer Case enables the driver to choose 2WD for dry pavement. Afterwards, mud, snow or crawling situations call for 4WD High or 4WD Low. Usually, this was accomplished through a lever in older trucks. Later on, a dash switch linked to an electric motor inside the Transfer Case did this. When four wheel drive is selected, the mechanical components send power to the front driveshaft which turns the front wheels. Likewise, the low range set multiplies torque to allow slow speed control. Full-time or all wheel drive systems incorporate a center differential or viscous coupling inside the Transfer Case. As a result, the front and rear shafts can rotate at different speeds without any binding or restriction. The critical failures manifest as a stretched chain, a chipped gear, or loose shaft connections. These typically show themselves as banging noises or refusal to shift modes. Any GMC Jimmy owner needs to respond to this before mobility is lost. Through the decades, GMC refined the drivetrain for the Jimmy. The basic function of the Transfer Case has remained the same. As such, the little gearbox is essential in every GMC Jimmy outing.
