How to change the manual gearbox oil on Toyota Yaris 2008? (The locations of the gearbox drain and fill in plugs)

'Transmission Fluid' in a manual transmission vehicle is called 'gearbox oil'. On the gearbox, there is a drain plug in the bottom somewhere and a fill plug on the side. You drain, clean the drain plug, replace the copper washer and put the drain plug back in. Fill the gearbox with oil until the oil starts to weep out of the filling hole. Replace the fill plug.

Manual gearboxes usually require a gearbox oil change every 30,000 to 50,000 mi (48,000 to 80,000 km). Automatic gearboxes usually have gear oil change intervals of between 60,000 to 100,000 mi (96,000 to 160,000 km). It's advisable that you change your gearbox oil filter at the same time as your oil.

I am not familiar with the model so I can't accurately answer your question.
There has been a number of European transmissions that weren't fitted with an oil filler/level plug, some were fitted with a level plug in the integral differential/final drive housing but the transmission shouldn't be filled through these. There have also been transmissions with no drain plug.

Many of these had to be drained and then refilled from the top of the casing by removing the breather or speedo drive and if no level plug was provided filling was by a measured quantity.

It is advisable to obtain good model specific information before you proceed.

There is no dipstick for the auto gearbox on this car.
There are 1 drain plug under the the gearbox oil sump (14mm), one oil level plug (hex allen key) and one filling on the gearbox case (24mm).

Only Totota WS fluid should be used.

Remove drain plug.
After fluid drains, install drain plug.
Remove fill plug.Fill with gear oil untill oil runs out of fill hole.
Install fill plug.

There should be a drain plug on the bottom of the gearbox. Unlike engine oil, usually the filling location for gear oil is on the side of the gearbox. You use a syringe or a specialised tool to get the gearoil in, and when it gets up to the level of the hole it's full. However I do agree with agent91 that your clutch is a more likely cause. there are some tests you can do to check the health of your clutch e.g. drive along in 4th at 40, clutch down, rev to redline, snap out clutch keeping your foot on throttle, and if revs don't drop to the correct speed in around a second you're slipping.

Hi,

Just checking.... it is a manual gearbox?

You may need a special tool for the drain plug and a 17mm allen key for the filler (some use the special drain tool for the filler as well)

The drain plug is located under the diff housing.

The filler plug is located on the left (nearside) off the gearbox (look to the left of the hole and you can see the 17mm hex filler bung).

Check you can undo the filler bung, then drain the gearbox oil.

Refit drain bung and fill gearbox through filler/level ********* until gearbox oil is up to the level of the filler bung.

Refit, test drive, check for leaks and retest level again when cold.

Cheers,

well there should be a drain plug might look a little flat on the bottom side of the tranny, thats were you drain the trans, to refill there should be a plug on the side of the tranny, your going to have to get creative on filling the trans until the oil starts to slowly trickle out . if you can get to the shifter and pull the shifter out and fill this spot

Here is a link to a step by step instructions on how to change the gearbox oil. If you don't want to change it, go to the refill portion of the instructions.
Fill it until the gear oil starts to run out of the fill hole.

is it manual tranny? if so u do so under the car by removing the fill up plug which is located on the side of the tranny on driver side of the car if i remember. The plug under the tranny is to drain it.

If u drain it, when u fill it back up, u do so until oil slightly spills out by way of that side plug.
