In most cars, the transmission filter resembles a “bug” screen designed to stop large particles of contaminants. In fact, many import cars do not have transmission filters at all. Too often, the transmission filter is confused in its performance with that of an oil filter. In most cases it is not necessary to change the transmission screen when performing a “T-Tech” service. The real value of T-Tech is your transmission now has 100% brand new fluid with high levels of viscosity to help your vehicle shift and run smoother. However, if you want to change the transmission filter when performing a T-Tech service, we can advise you of the availability and additional cost of the service.
