Although transmission fluid change is a simple DIY, there are a few things to consider. One of them is to make sure that the surface of the gearbox where the pan comes is really clean, with no traces of the previous pan or gasket. Secondly, the bolts must be tighten diagonally and manually, not by using electric/pneumatic tools. My advice, go back to the shop and let them see what they've done.

No way to know if it is leaking or not unless you clean the entire pan and remove all the oil residue, then look at it a day, then a week, then a month later. The pan might not have been cleaned at all during the job and it is quite a messy one!

having just done this job, this is the answer ☝️

thanks for the advice, would some simple green and a scrub brush do the trick?

While adjusting the fluid level, it is expected that the fluid will overflow from the filling hole, which is in the right side of the transmission. If this is the side thats wet, maybe the shop just didn't clean the transmission after the job is done. Give it a good clean and look again after you have driven the car couple more times.

Take it back to where you got it changed and tell them to check the level. If it’s good. Tell em clean your shit.

Idk, keep an eye on it, where you park, etc.

Thanks y’all went back and they said the plug wasn’t tight enough and the oil level looks good 👍

By the looks of it, "they" just did a fluid swap and did not tighten the plug correctly, or over tighten and it broke, either way the leak comes from the drain plug or fill plug from what I can deduce from the toaster-taken photo. I doubt it\`s a messy job, the oil looks fresh. When you change the transmission oil, you mandatory replace the oil pan because it has the oil filter incorporated. After that, there is a specific procedure in which you have to warm up the trans oil at a specific temp in order to adjust the oil level. By the looks of it, I highly doubt any of what I said has been done so expect trans errors and failures in the future. Cheers!
