Trans Bands
for your 1986 GMC C1500 Suburban
Within the transmission housing of your GMC C1500 Suburban are two steel trans bands that are actuated by two pistons and hydraulic cylinders. These automatic transmission components work to connect and lock the gear train to the housing unit. The transmission is the part of the engine responsible for shifting gears either during acceleration or deceleration.
Properly working trans bands help your GMC C1500 Suburban shift safely and consistently between gears. Hearing grinding noises or seeing the transmission indicator light come on might indicate trouble within the housing unit. Replacing worn or broken parts as soon as you notice a problem, which will save costly repairs from overwhelming your budget.
