Liqui Moly offers shops fully automatic transmission flushing
Ulm, Germany—As improved engineering, machining of parts and tighter tolerances of vehicle manufacturing intensifies, the aftermarket service and repair industry is increasingly focusing more on maintenance and service schedules, rather than repair. One growing opportunity and profit center for shops is transmission service and flushing.
“The age of a lifetime fill of automatic transmission fluid is over,” said Steffen Niemietz, application technology expert for Liqui Moly, due to technical requirements of oil in modern automatic transmissions. “All manufacturers now recommend using a flushing machine.”
Without using a flushing machine and just draining oil from the pan, only half of the used oil will be removed as the residual will remain in the convertor side of a transmission, he said. “An automatic transmission flushing machine is highly recommended by vehicle manufacturers to flush out the system completely.”
While the aftermarket has numerous manufacturers of transmission flushing equipment, Liqui Moly differentiates its recently introduced Gear Tronic as a fully automatic machine,” Niemietz said. “There are manual and semi-automatic machines on the market, but Liqui Moly has provided a way to perform the service that’s easy for the technician and safe for the vehicle. In addition to the Gear Tronic, we also offer many adapters, primarily for European cars, that can be easily searched and identified through our database with user instructions. The machine is just one piece of the puzzle.”
How it works, benefits
A technician has no need to adjust a gear box oil pressure or oil flow direction, Niemietz said, adding that there are different ways to connect the machine to a gear box, such as from the gear box to the oil cooler or through the dipstick, as may be the case with older cars.
He explained that once the Gear Tronic is set up to a vehicle, the car’s engine is started and the equipment will first determine if the oil flow direction is correct by providing the technician with a green light signal. If there is no green light, then the user turns the engine off and switches the connectors to the gear box so that the oil flow is correct.
When correct flow is established and the engine is running, the machine automatically adjusts for proper oil pressure and the Gear Tronic uses its boost function to administer fresh oil, as well as any additives, into the transmission while pushing out the old oil. “This guarantees that the transmission never becomes under-lubricated,” Niemietz said.
During the treatment, the technician can easily monitor the new oil quality entering the transmission compared to the old oil leaving it. “As soon as the old oil looks similar to the new oil, it means there’s been a complete fluid change and the user presses the stop button,” Niemietz said.
