Detect transmission problems by observing leaking fluid, listening for whining or clunking noises, noticing gears slipping, smelling burning odors, feeling grinding or shaking and recognizing a lack of response. Other ways to detect transmission problems include noticing a dragging clutch or check engine light.
Detecting transmission problems requires the use of four out of five senses. When leaking red fluid is present under the vehicle, there are issues with the transmission. If you notice a burning smell, this may also relate to problems with the transmission. This distinct smell can occur as a result of overheating transmission fluid. Drivers who hear a whining, clunking or humming noise after shifting gears can easily diagnose these noises as a problem related to the transmission.
Whenever a vehicle refuses to enter gear or slips out of gear, there is a problem with the transmission. Vehicles that experience gears slipping while driving are at risk of a dangerous driving condition. In some cases, drivers notice the vehicle will not shift from park to drive.
Another common issue associated with the transmission is a lack of response. This happens when the driver attempts to shift gears and a delay or hesitation occurs before the gear is fully engaged.
