First off happy turkey day eve everyone ☺

So my dad's Jetta battery died because it was getting old, he called me while I was at work to ask if I was available to jump start it for him, the next morning I pull my 03 g35 sedan 5at out the garage and as soon as I put the car face to face with the Jetta I noticed a huge oil leak happening under my car. Immediately I shut the car off and investigate where it's coming from. I take the undertray shield off and noticed that a hose has been disconnected from what I believe is the oil cooler? The cause of this was a rusted hose clamp which eventually broke and somehow the hose came off and leaked a puddle of oil on the streets, it didn't come off in my garage because the floor was spotless so it must of happened within the 10 seconds of me driving it while pulling it to the front of our house. I filled my engine with 1 quart oil so I could drive it back in the garage for a bit, later I checked my oil level multiple times though he day and it says it's a little above H so I drove it a bit, I've noticed that when I accelerate I need to press the gas more and it doesn't really get up to speed right away I'll be in 3k rpm and it would finally shift the gear so it feels like the gears have been slipping.
My question is did I break something internal when I lost some oil or did I just loose transmission oil and that I should drain and fill? Here's a picture I already replaced the hose clamp






This is by the passenger side

 

It's possible you hurt the transmission but you won't know until you refill it and drive it. Make sure you get the right transmission fluid and you check it correctly.

 

That is the line for the transmission oil cooler. Not motor oil.

Depending on how much you lost, the transmission could be damaged already.

 

Thanks for the reply guys, yes I've searched the fourm and googled about transmission fluid whether or not to flush or just drain, but non seemed to have the problem I had. so would you guys just recommend I drain and refill? Or should I just add some fluid to top it off? I'll go stop by Nissan or infiniti dealer for the fluid Friday

 

At this point, may as well do a drain and fill. Whats the mileage on the car?

 

178k fsm says I need 10 quarts but I think I've read somewhere it's only 10quarts if I remove some drain pan is this correct?
