The more I think about it and the way the transmission is acting it is very likely that the fluid is low.

So here's the question if it is low what synthetic transmission fluid do I add to it?. If adding fluid will correct the problem then yes I will go ahead with the service. Especially with that many miles on it.

I do appreciate your input and I thank you very much. I will try the things you've suggested and go from there.
Many people use the Valvoline Maxlife ATF

The transmission fill procedure is not complicated at all.

You need to have the transmission at normal operating temperature and when you unscrew the fill plug there should be a slight trickle of fluid coming out.

If you are worried about driving the vehicle then let the engine run until it comes up to temp (needle in the middle) and shift into each gear for a few seconds. R N D etc. Then check the fluid level.

Basically the trans fluid will expand when heated (like most fluid) so if you fill the transmission to the proper level while it's cold once you're driving around the fluid level will be too high.

The transmission shop that I deal with specializes in European cars and while I had my car there for a flush I was asking the guys all about the pain in the ass fill procedure. They said it's not that sensitive and proceeded to walk me through it on my car.

If you read how to do the fill procedure from the manual it sounds a LOT more complicated than what it really is.
