Transmission fluid/filter change
by certified professionals
At O’Neill’s, we use all OE manufacturer fluids. Three things that make transmission work smooth: fluid, vehicle software, and friction component. It is critical to use the manufacturer fluid. Generally, a transmission service replaces about 1/3 to 1/2 of the fluid inside the transmission, which is adequate for a regularly-maintained transmission. For more severe instances you may consider a transmission flush.
A transmission flush is intended to replace nearly 100% of the fluid in your transmission. It requires a specialized machine that pumps new fluid through the transmission’s lube and cooler circuit, replacing the old fluid.
A word of caution: these flush machines do not require replacing the transmission filter in order to exchange the fluid. If you elect to have the transmission flushed, we will have the filter replaced as well, provided the filter is accessible. Some transmissions, like those used in most Hondas, are not accessible and cannot be replaced without disassembling the transmission.
Your decision to consider a regular service or fluid exchange can be determined by the condition of your transmission fluid.
