This is a DIY manual of transmission/gear oil change. The following is the original article.
Sharing simple DIY you can do on your own for changing of manual transmission/gear oil
This is not my car but i find the pictures taken is much clearer than mine so i uses it.
NEXIQ 125032.

steps
1) Find out the type of oil you need and buy it.
My car uses 75w90 oil and need 2L. It is better to use fully synthetic oil as it last longer.
But I myself uses 80W90 castrol MTF.

2) Get ready some spanner, usually the bots uses 24mm

3) Unscrew the wheels

4) jack up the car and remove the wheel

5) Get ready a container to collect the used oil

6) The top screw is for topping up the oil and the below screw is for draining
Unscrew the top then the below.

7) Let the oil drain out.


8) clean the bots that u unscrewed.

9) Find a used bottle, cut off the top and attached a tube for filling up the oil
any method is ok as long u can use a tube to fill up the oil

10) After the oil finished draining, screw back the bottom screw.
connect the tube to the top hole

11) start pouring in the oil, once it is done, take out the hose and screw back.
*usually oil will start dripping out from the top hole once u hit the require amount of oil needed.

* I used a pump to pump in the Manual transmission fluid, much faster.
It cost me $16 for the 2 bottle of 1L castrol MTF, my car use about 2.1L of oil but it is ok.
Cheap and simple. Just a little time needed for the DIY

 

Same way I fill mine!! A lot faster and easier!!!
