close up of a transmission

Though transmissions are generally reliable, there are a great number of issues that can develop with one. From TAG Automotive Repair in Flagstaff, AZ, here’s a general overview of the types of problems your transmission may develop, all of which we service and repair.

Slipping/Shifting Issues - In order for a transmission to operate correctly, there are certain conditions that must be met. Pressure must be regulated to the correct parameters; pressure which is controlled and monitored by various sensors, cables, or vacuum lines (depending on the transmission) and reliant upon the condition of lines, the pump, the filter, seals, and other components. Anywhere pressure is too high or too low as a result of a faulty part or misdiagnosed as too high or low by a faulty sensor, shifting issues will likely arise. The hard components affect shifting as well. Clutches, valve body components, valves, and solenoids all must be in good condition and operating freely. If these components wear out or begin to stick as a result of wear or poor maintenance, shifting and engagement issues will occur.

Leaks - There are seals and gaskets at the front and rear, the pan, the shift linkages, the tail housing, sensors, and so on, depending on the transmission. These seals and gaskets only have one job - to keep fluid from leaking out. Since much of the transmission is pressurized and fluid is constantly moving throughout, it doesn’t take much for one to leak. Leaks come in all sizes, and every one requires a different procedure to repair - which is why it’s important to have a professional transmission expert diagnose the leak correctly. A pan gasket is simple, part of any routine filter replacement, while a front seal requires removal of the entire transmission.

Programming - Modern transmissions have to be programmed correctly to operate correctly, and one that needs programming is at risk of damage. Programming a transmission requires specialized equipment, and is necessary whenever work is done that affects the operation of the transmission, whenever the transmission is acting erratically, or sometimes even as a result of a dead battery on the vehicle.
