So one of the transmission cooler lines connected to the radiator fell off the other day , i was half a block from home and i only noticed because it was slipping pretty bad for that half block , well i fixed the leak but i dont want to drive it , i know i can fill it from underneath the car but is there any way to just add the fluid lost from under the hood ? or is the only possible way to add fluid from underneath? thanks ! fluid was recently changed which is why im not to concerned to change it again, i just need to add what was lost. Any help is appreciated (:
Edit: Vehicle is a 2010 G37 with 7AT

 

yes

you have to fill from underneath

not hard at all if you've done it once.

it's always the first time that's the worry

 

oh wait you have a cooler? you might be able to pump it in through the cooler line, but you still need to get underneath the car to gauge the correct amount of fluid. I don't know how youre going to do that in your case since the thread I referred to only measured what came out and put the same amount back in. I think there was a way to gauge the level on youtube or google search.

This is what I referred to when I did mine.

I would just have it towed to the dealership and have them fill it up. Not worth the time and effort. They shouldn't charge more than 150 since a fluid change was 139 for me.
