I own a Nissan Sentra 2010. It is a manual transmission. I was curious on what I should be doing for general maintenance. I have been gone for the last two years, and during that time my car was driven maybe three times a month. I know it needs an oil change, but are there any other maintenance needs for a manual transmission and clutch?
It is good that the vehicle has been driven monthly, and you may have saved yourself a lot of time and maintenance by doing this. An oil change is critical and should happen first. When it comes to the transmission, the fluid can absorb water while it sits (as can the brake fluid), and cause the gears to bind and grind. You will want to change the transmission fluid and the filter, especially if you live in a humid area. You will want to make sure all of the other fluids are topped off, that your tires have not developed flat spots, that the battery can pass a bench test (done at automotive parts stores for free), and that any old fuel gets diluted with new gas and cycled through. Changing the fuel filter is also a good idea, but you want to do it only after the old gas has been cycled through. Good luck!
