So i had my transmission fluid exchanged on my ‘15 is350 f sport at the dealership yesterday. today i took it to another shop to have the curb rash fixed and noticed a spot on my garage floor. at the time i thought maybe it was from my other car that i know has a leak that was parked there the day before. picked up my car today from the wheel repair it sat for a couple hours and there was another spot. i had this car on a lift less than a week ago and it was bone dry. my question is what could have gone wrong during the tranny fluid exchange that would now cause it to leak? it’s back at the dealer now but they won’t get to it till monday. honestly i just bought this car and am now i’m a little worried that i messed it up by just trying to do the right thing and do some regular maintenance. any help here is appreciated guys thank you!

 

On the tranny there are 3 plugs...drain plug, fill plug, and overflow plug.
All 3 get removed/installed during a fluid change.
It's likely that one of them is not tight enough and leaking fluid slightly.
I'm sure it will be an easy fix for the dealer to get you up and running again.

 

thank you for the response i really hope you’re right. i don’t think i lost a ton of fluid but i wonder if they would try to refill what was lost? i really hope it’s what you mentioned above and not something like the seals.
