When cold drives nice and smooth, and even when warm you can go days sometimes with no issues, and then all of a sudden when you are about to slow down around second gear she downshifts hard, code p0732, I want to replace the fluid but I also want to see if this code is related to second gear solenoid and how to replace it, it's a shot in the dark but am willing to do it.

Hello,

The code is the problem which is for the input shaft sensor for the transmission. Here is the location so you can change it out. Check out the diagrams (below). Please let us know if you need anything else to get the problem fixed.

Hmm, that would be easy to change for sure, but why is it saying gear 2 incorrect ratio?

Finally was able to get the sensor and replaced it, took a minute to find it because it was under the shifter cable. Cleaned two other sensors just in case. She is now in limp mode, and I have engine and transmission codes that are the same, o2 and knock sensor. At first when I drove it it jerked when I was slowing down once, and gave the p0732, and the others, cleared it and drove, limp mode as in probably third gear p0326, p0057 and p0137.

It sounds like you have two issues. We will handle the transmission problem on this post. Can I ask if the speedometer is working correctly?
