  • Trans Tech II Transmission machine is a self-contained system which connects directly to the transmission through the transmission cooler lines. The Trans Tech II completely exchanges 100% of the transmissions fluid while removing all internal debris. This cleaning is accomplished using only automatic transmission fluid and no solvents or chemicals which may shorten the transmissions life. The specified type of fluid is exchanged through the vehicles transmission till the unit is completely clean. This service is hands down the best way to replace virtually 100% of the transmissions fluid, without removing the transmission pan which could cause additional internal issues. Modern transmissions do not contain a 'filter', but use a debris screen. This screen is cleaned by the machine performing a back flush procedure to remove trapped debris. In some instances, where paper filters are used, the filter may need to be replaced depending upon the condition of the fluid before the service. Fluid is additional. Filter and pan gasket additional (if required).

  • Remove the four tires from the vehicle, and clean the wheel studs, hub flanges, and the rims centric. Check the vehicles braking system components for wear, remaining brake material, and signs of pending issues. Reinstall the tires onto the vehicle in their best suited locations based on overall wear, torquing all lugs to factory specification. Inflate all tires to the manufacturers suggested pressure, and visually assess the tread for abnormal wear which may indicate a need for a wheel alignment. Reset the vehicles tire pressure monitor sensor locations where required, using the factory approved TPMS (Tire Pressure Monitoring) system, scan tool. Road test the vehicle and confirm there is no abnormal handling characteristics following the rotation. Note: Some vehicles may have a slight drift following a tire rotation. This is due to a pattern that developes in some tires due to excessive time in one location. This condition should improve as the tread conforms to the new location / alignment angle. If drifting would not improve, sometimes an alignment or a cross rotation is required.
