The sound of an automatic transmission red-lining because it can't or won't up-shift is about as painful as listening to jagged fingernails being dragged across a blackboard. Often times, the problem with sticky shifting is not mechanical but electrical, including a faulty gearbox switch. Luckily, repairing your gearbox shift is far more affordable than a complete transmission overhaul, especially when you shop at AutoAnything. That's because AutoAnything guarantees the lowest price for your gearbox switch, and gives you free shipping with your order.
