Transmission Got a toyota axio 2008 model, my transmission seal went bad in the axle causing the fluid to leak out , replace the seal, but unsure as to how much fluid to put back i added 4 litters is it enough?

SOURCE: Toyota Prius 2008 - Transmission or or fluid?

Here is the answer that you are looking for: Never.
The auto trans fluid in a Prius is what we call "World Spec", and never needs to be changed. Why? Because the Prius trans fluid is not used for hydraulic pressure or cooling the ATF fluid due to the lack of the aforementioned hydraulic pressure. All that the ATF does is perform a "lubrication" function. As long as there is no contamination of the fluid (such as being in a flood), do not bother with it.

SOURCE: 2007 Toyota 4 runner transmission filter and fluid change??

at 50,000 miles there is really no need. i would wait and save up that money and do a transmission flush 7- 10 quarts of toyota f-type fluid can be costly but a flush removes all of the fluid and garnish along with any fine shavings (normal wear and tear) out of the tranny and replaces it with new clean fluid. normal intervals would be at about 80-100,000 miles. you should be able to find preventative maintenance schedules in your owners manual. if not any repair facility would have it on their computer.

there is no dipstick it's a sealed unit dealer only.sorry a lot of vehicle manufacturers have went to this sealed style some ford suv's,tacomas,dodge chargers challengers and magnums.just a few off tof of my head.it's one of those BETTER DESIGNS THEY ARE ALWAYS COMING UP WITH TO MAKE YOU BURN UP A 5000 DOLLAR UNIT IN HOPES OF SELLING ANOTHER TRUCK TO REPLACE THE ONE THATS TORN UP.....SORRY oh ya the transfer case has a regular old check plug 28 mm i think don't quote me could be a 30 or 32 also they changed up on those.

SOURCE: oil leak problem with 1996 toyota camry

I am going to see a mechanic - my trusted mechanic who does not nickel and dime me - to see what this is. I have the same problem and he told me he has never done this job on a Camry and is unsure. Given the miles, he has suggested that maybe it is time to part ways with the car. I am going to ask him if he will put some florescent dye in it and let me drive it for 50-100 mi and then check to see where the leak is and fix it. Let you know what happens. I have to try, the car is solid.
