A person can determine if their transmission is slipping by watching the revolutions per minute, or RPM, gauge. If the gauge reads more than 3,500, it can indicate a slipping transmission.
Another sign of a slipping transmission is if the vehicle it taking longer than normal to coast when the brake is pressed or taking more time to shift into another gear. Taking longer than normal to accelerate when the gas pedal is pressed is another symptom of a transmission issue. All of these symptoms can be indicative of an issue other than the transmission, however.
When a transmission begins slipping, the car owner must first determine the cause in order to have it properly repaired. The first step is to ensure the transmission fluids are at the correct level as this can cause the component to malfunction. Sometimes, the transmission might slip due to a defective gear shift, a worn gear or bad transmission bands. These problems are more difficult to fix and a mechanic with experience is often required for repair.
A thin or weak clutch can cause transmission slips in both automatic and manual vehicles. If this is the reason for the problem, the clutch needs to be replaced as soon as possible.
