Engines & Transmissions
Regular preventative maintenance is critical to prolonging the lifespan of any vehicle part – especially your car’s engine. This will ensure peak performance and efficient fuel economy.
One key part of the engine is the cylinder head. It’s the closed end of a cylinder (located in a car's engine block). It sits above the cylinder block, closing the top of the cylinder and forming the combustion chamber. The cylinder head coordinates airflow in and out of the engine. Since the cylinder head's chief function is to seal the cylinders properly, insufficient compression results in the car being difficult to drive.
Another important part of the engine is the timing belt. It is part of your car’s internal combustion engine. The belt synchronizes the camshaft and the crankshaft rotation so the engine valves open and close at the right timings. The belt also prevents the piston from striking the valves in an interference engine. Most modern cars have timing belts instead of timing chains and gears. Follow your car’s manufacturer suggestions for timing belt check ups.
A transmission service is part of your routine maintenance, just like replacing your engine oil.
A complete transmission service should include:
• removing and examining the sump or pan (where possible)
• replacing or cleaning the screen or filter
• cleaning the pan
• reinstalling the pan with a new pan gasket
• pumping out the rest of the old fluid and replacing it with new, high quality ATF
• adding a friction modifier or additive package (model specific)
New fluid restores the holding power between the clutches, reducing slip and heat production. Flushing the old fluid washes away tiny particles of clutch material and metal shavings. Those particles clog passages and wedge between moving parts, causing wear throughout the transmission. Changing the fluid eliminates those particles and the wear they cause.
The net result of changing the fluid is to provide better lubrication, improved the holding ability of the friction components, and reduced heat. So your transmission works better for years longer, which means you’re less likely to face a major transmission repair.
