Slipping may feel like the engine revs without a matching increase in vehicle speed, or like power briefly drops during a shift. The cause can involve fluid level, hydraulic pressure, controls, or worn internal components.
Other vehicle problems can create similar sensations, and some transmission designs behave differently during normal acceleration. Diagnosis is needed to distinguish expected operation from a fault.
Contact Certified Transmission at 12908 S US Highway 71 in Grandview. Avoid repeated hard acceleration to reproduce the symptom because continued slipping can generate heat and worsen damage.
