The automatic transmission fluid for the Honda City should be changed every 40,000 kilometers, while the manual transmission fluid should be replaced every 60,000 kilometers.
For manual changes, 4-6 liters of fluid is required, whereas 9-12 liters is necessary when using a flushing machine.
Regarding the fluid change methods for the Honda City transmission, the first method is gravity replacement, which is similar to changing engine oil. You need to loosen the oil pan bolts to allow the transmission fluid to flow out by gravity.
Although this operation is simple, it does not completely clean the transmission fluid, and dirty old fluid can easily remain in the mechanical nooks and crannies.
Secondly, you can use a flushing machine to change the new transmission fluid. By connecting the flushing machine to the transmission oil circuit, the new transmission fluid will push out the old fluid under pressure, allowing for a more thorough cleaning.
Each flushing process requires approximately 10-15 liters of new fluid, and the entire procedure takes about 40-80 minutes.
Finally, you can also opt to remove the oil pan and change the oil, which allows for a more thorough cleaning of the oil circuit and the replacement of the dirty oil filter.
Removing the oil pan is a complex task that may increase labor costs.
Symptoms of degraded transmission fluid include:
Slippage, where the engine RPM rises without sufficient power;
Leaking oil, leading to inadequate internal lubrication;
Jerkiness, causing the vehicle to shake during shifting;
Unusual noises, possibly due to gear deformation or sediment in the oil pan;
High temperature, usually indicated by a transmission temperature warning on the dashboard;
Stalling, which may be due to a faulty input shaft speed sensor.
Applicable model years include 2019, 2018, 2017, and earlier versions.
