What Is a Transmission Tune-Up?

A basic automotive transmission tune-up involves inspecting and replacing the gasket, filter and transmission fluid. The transmission bands may also be tightened and adjusted during a routine tune-up. CarTalk recommends a transmission tune-up every two years or 30,000 miles.

Frequent stop-and-go driving and hauling heavy loads can accelerate the deterioration and contamination of transmission fluid. Engine surging, delayed engine response and slipping gears are symptoms of contaminated transmission fluid. Spots of red fluid on the ground beneath a parked car may indicate a transmission gasket leak.

Periodic transmission service is a crucial part of automotive maintenance. Inspection on a car lift may diagnose serious transmission problems. Regular transmission tune-ups can prevent serious damage that requires major transmission repair down the road.
