so i looked under my car and saw a drain plug

thought that was it, put the pan underneath and undid the plug

surely it was oil that came out, orangey and had grimey bits in it, but why only 2 litres?

maybe the car wasn't at the right angle, my driveway is an incline so the car was sloping down

perhaps i need to move it up the driveway so the car is sloping up

car is too heavy shit

fuck can't start up the car now there's no oil (or so i thought)

ok so fuck it i'll just put the old oil back in, start the car up and move it and then re-drain the oil

so i undo the drain plug again

wtf why isn't anything coming out????

oh there's another drain plug

fuck

undo that and 4 litres comes out

(in my head: maybe this car has 2 drain plugs, i've already had it's fair share of odd french curiosities)

anyway i put it to the back of my mind, fill her up with the new oil and change the oil filter

starts up nicely enough (didn't bother to check the oil level at this point, 4 litres out, 4 litres in)

go for a drive round the block, about 4 km in i notice it feels a bit sluggish. maybe i have too much oil?

now my stereo is on pretty loud so i don't hear much, but there's about 10 seconds of silence as the song 
changes

and when i shift gears i hear a screech

wtf

i turn off the radio and shift through the gears

why is it fucking screeching?!?!

and then it dawned on me

i've just completely drained the gearbox fluid

put 2 litres of gearbox oil into the engine

and then put another 4 litres of fresh oil into the engine

so my gearbox has no oil, and my engine has about 7 litres of oil (meant to have 5)

and i'm just sitting in my car on the side of the road, knowing exactly how i've fucked up

and not being able to do anything about it

 

tomorrow i'll get some new tranny fluid and flush out the engine again

what damage have i done?

(before today i didn't know where a transmission was in a front-engined econobox, i just assumed the whole assembly was "engine")

TIFU by draining my gearbox oil instead of my engine oil
