Luke ShaffQuestion:
My friend just had a very expensive transmission repair in Bellevue. How can Redmond drivers like myself avoid transmission trouble?
Luke's Automotive Answer:
Next to your engine, your transmission is the most important component in your vehicle – so you and your fellow Redmond drivers want to do all you can to avoid transmission repairs.
Redmond drivers may have noticed a trend of engines becoming more and more powerful in recent years. At the same time, fuel economy has been improving in nearly every motor vehicle segment in Washington. More power and better economy have always been at odds. Some of the improvement in fuel economy has been due to engine design, but most of the increases can be credited to advances in transmission technology.
Every engine has a sweet spot in which it most efficiently makes power. This is often referred to by Redmond technicians as the power band – the optimal engine speed (measured in revolutions per minute, or RPM). The computers that control what gear your automatic transmission is in also try to keep it in the right gear in order to maintain optimal engine speed – whatever your Redmond driving conditions may be. Modern automatic transmissions have anywhere between four and ten speeds. The more “speeds” your transmission has, the more time your engine can operate at peak efficiency. Needless to say, transmissions have become more sophisticated.
Transmissions are cooled and lubricated by transmission fluid. This pressurized fluid is directed through small passages to effect gear changes. When transmission fluid gets old and contaminated, the small passages can become plugged, which adversely affects shifts. The dirty fluid circulating in the transmission can eat away at gaskets and seals, causing internal leaks that also hurt shifting. This is why some recommend that transmissions be serviced from time to time. The interval varies by vehicle, so check your owner's manual or speak with your friendly and knowledgeable Luke's Automotive service advisor about your transmission service recommendations.
Old, contaminated fluid is removed and new fluid is installed. Keeping up with the manufacturer's recommended service schedule helps prevent internal damage that may result in a transmission rebuild. Let Luke's Automotive help you extend the life of your vehicle and prevent repairs with recommended preventive maintenance service.
