How often should the transmission fluid be changed for a Cadillac XT5?

[VeraRose]

Cadillac XT5 transmission fluid should be changed every 2 years or 40,000 kilometers. Purpose of the transmission: A device that changes the speed ratio and direction of motion. It is used in automobiles, tractors, ships, machine tools, and various machines to alter the torque, speed, and direction of motion transmitted from the driving shaft to the driven shaft under different working conditions. Gear-driven transmissions generally consist of a housing and several gear pairs. Combined transmissions are formed by connecting two transmissions in series or parallel to achieve more gear ratios with fewer gears. Main functions: Under constant engine speed and torque, it changes the driving force and speed of the vehicle (shifting); allows the vehicle to move in reverse (reversing); and enables the engine to idle without stalling (neutral). Based on the transmission type, gear transmissions can be divided into three types: two-shaft, three-shaft, and combined. The two-shaft type has two main shafts (excluding the reverse shaft) and only undergoes one pair of gear reduction. The three-shaft type has three main shafts (input shaft, intermediate shaft, and output shaft) and undergoes two pairs of gear reduction.
