Grateful for any advice:

I accidentally mistook the transmission pan plug for the oil plug.

Sounds like I only drained about a third of my transmission fluid from what I've read; issue is I drained it into the cutout 5 quart container I use for oil changes.

There were a couple of spoonfuls of used motor oil in the container that likely got into the transmission fluid, and I put the fluid back into the transmission.

It sounds like a transmission flush will do more harm than good. The car has never had the transmission fluid changed before.

I haven't run the engine yet.

Should I change the transmission fluid, or is that small amount nothing to write home about?

That small amount is nothing to worry about. for peace of mind you might want to drain and top off the transmission but I wouldn't worry about damaging the transmission.

So you put contaminated fluid back into the trans ? Good luck for me it would be time for a flush and refill because I believe in doing things properly

Cheers Bill, sincerely appreciated!

Hahaha...reminds me of a situation I had one morning at work. I was the loaner manager for a Lincoln/Mercury store. I had 250 vehicles in my fleet. One morning at 6:55am (we opened at 7am, but this woman was insistant on getting to work) I had a woman demand that I give her a minivan even though she had a Tracer in for service. Whatever. I wasn't in the mood to deal with it so I had my porter grab it and pull it in the garage so we could give it a quick clean (it had only been out for 5 hours the previous day and my porter kept my cars spotless). I popped the hood and proceeded to put washer fluid in the coolant tank... If you've ever seen a Mercury Monterey minivan, they put the coolant and the washer fluid side by side to each other. It was early, I hadn't had my shuttle driver bring my coffee yet, I was irritated with the customer, and my porter was giving me a hard time because I caved in and gave a Tracer customer a brand new minivan when she should have had a Tracer. Not too mention my wife had called me and said one of our daughters was throwing up so she wasn't coming into work so I would hear it from her manager (we worked in different departments...and yes, I was read the riot act by the owner when we were dating. But we kept it a secret until we were engaged). Needless to say, the woman did not get a minivan!!! HAHAHAHA...... She got my Lincoln LS demo instead.

So...been there, done that...no harm, no foul. 2 teaspoons is going to do absolutely nothing IMHO. But on the other hand, way different viscosities. And if you only change it every 100k, I might consider re-doing it.

"Properly" seems a subjective term in this scenario, mate.
