noob on Saga BLM wanna ask something:

I want to DIY the ATF replacement for my wife's BLM, so here are some questions:
(1) How much ATF needed?
(2) Where is the drain plug for the gearbox (I haven't take a look at the underside of the car - yet)
(3) Where to pour in the new ATF? Is it through the ATF dipstick hole?
(4) How to properly check the ATF level?

regards,
Neotoxin

for some people, DIY is a satisfaction

i have jack, wrenches and funnel. Anything else needed?

Thank you for your reply. For no. (3) I think there's enough space to put the funnel without extension tube (actually I have this custom-made extended funnel made from mineral water bottle and flexible pipe for changing GB oil of my Wira ). I need to research more on no. 4... thank you

Thanks for all replies.. I did my ATF change last week.

To sum it up
1) Drain screw size is 24mm. Need a socket wrench for this (I was using the ratcheting type)

2) The drain screw is located at inconvenience place - just above the lower arm on the left side (@MR_alien did mention about this). Without proper guttering, the old ATF will spill all over the place.

I improvised a plastic bottle as a gutter

3) Almost 5 litres (5 bottles) of SPIII ATF needed for replacement (mentioned by @erictioh). 4.5 bottles of ATF just barely above the HOT mark at 'N'. Refilling ATF is easy - just need to put funnel and pour the ATF in (no need extended funnel)
