Let's Talk TORQUE (Pro)

Just got back from a trip to AZ. Some readings I got off my Torque app.
1) Trans Fluid Temp (TFT1) is always =/< TFT2. So is TFT1 the pan temp & TFT2 the T/C temp? What is an acceptable range for these?
2) CAT B1S1 is always = CAT B2S1. CAT B1S2 is always = CAT B2S2. Bank 1 is always < Bank 2. Is this right/normal? Seems like there should be some variation?
3) LTFT1 steady @ 2.34, LTFT2 steady @ 4.96 for entire trip out. During driving locally in AZ & for about 1/2 the trip home LTFT1 = 4.69, LTFT2 = 6.12. Then the values returned to previous readings. No noticeable change in MPG or performance. Ideas? Should I even care about the difference between the two banks?
4) What is an acceptable coolant range for a fully warmed engine? (at least 50 miles driven) I usually see between 180 - 195 F.
All readings from 07 4.0L SR5 4wd ~235,000 miles.
Thanks for reading.

 

You're welcome. I like to read.

 

4) Those numbers sound normal to me.
