*Update
Since I started this thread I've had the Tranny oil flushed and replaced, Coolant Flushed and replaced (still running Gold) and new CAC boots. The readings below are with the new Trans Fluid Gauge, Also the Delta Gauge and a non working gear gauge . This was taken in my driveway idling after driving 40 miles HWY pushing it somewhat hard, some slight hills and a little city driving. This was at 7:48 am, the ambient temp was around low 80's and there was 3 passengers. I will try and take one while cruising at 65 but if memory serves me right, I saw about 6-8 degree delta difference.
If towing or climbing a long steep hill should the delta reading ever pass beyond the 10 degree difference? or is this mainly a reference when cruising?
Wonder what's up with your gear gauge. Might try deleting it, then with truck running and torque screen up re create it. When you get to the PID selection list, that PID should come up Green, as in the ECM/TCM is providing it. Also check adapter status to see if you are getting any comms errors, you can adjust query speed and such to help out if it is a flaky adapter issue (I've had one that was hit and miss).
Yes, you will see temps climb and a larger spread on a long grade. Mine hangs around 7 - 8 deg oil above coolant at steady 65mph (empty) on a 80ish day....

Glad the trans temp is working now...

Got the gear gauge working although it shows 6 gears. How many does yours show?
^^^^^ What he said Though in case you hadn't read it before: it only uses 5 at a time if it is too cold, it decides whether 3rd or 4th is used (I think it is those two) -- Bryan will tell me if that is incorrect...
I remember hearing something along those lines of having 6 speeds, what I find weird is I never saw 4th gear. I'll check again. Thanks
I just got back from a nice drive in my guy -- watched the gears since this had come up. 80 or so degrees out and I never saw 4th either, so I'm pretty sure 4th is the option gear...
It's really has 6 forward gears. It's a compound unit, has 2 up front, 3 in the back, combined for 6 possible gearings. Two of them are so close they're indistinguishable, and the TCM program chooses based on TFT which shift it should make.

The trans is a two speed in front of a three speed.
First gear is both sets in first gear. (1:1 time 3.11:1 = 3.11:1)
Second is the front upshifted and the rear still in first.(0.71:1 times 3.11:1 = 2.2:1)
Third is the front back in low and the rear in second. (1:1 times 1.54:1 = 1.54:1)
Fourth is the front in high and the rear still in second. This is the one used when cold. (0.71:1 times 1.54:1 = 1.09:1)
Fifth is the front in low and the rear in third. This is 1:1 on both sets.
Sixth is the front in high and the rear in third. (0.71:1 times 1:1 = 0.71:1)
Fourth is used cold because it was easier to get the trans to do this shift in extreme cold. The 3-5 shift didn't work very well cold, so this was the best way to make the trans work when cold. It stops using fourth when the trans is above 0F, so it doesn't stay in this mode very long.
Unless your TFT is <0*f then you'll skip 4th and never see it.
As for 4th, it will use 4th gear when warm, but, everything must be perfect for it to happen.
I managed to get it to go AND capture it on video. I really had to work at it. It's not something a person should be OCD about finding 4th.
*2nd Update
Just got back from a 3 day trip to southern California coast. Was in San Simeon, Pismo Beach, Moro Bay, Atascadero and then to Solvang and passed Santa Barbara. Truck worked as expected, I was able to see that the cruising delta was around 6 on highway at 65mph and increased to about 8 if going over 75. The highest I saw coolant was about 204 and that was on long climbs other then that it was around 186 with ambient temp being at 70's and mid 190's where temp was high 80's. Tranny never went higher then high 180's. EOT went up to 210 on long climbs with ambient temp being around high 80's but then when the road evened out quickly went back down to a 6-8 degree delta. Sorry for the lack of pics, decided to keep two hands on the wheel. Thanks for all the help, looking forward to going out this weekend and also playing with the idea of having an F350 to carry a Camper around, We'll see.

First: Thanks for the follow-up Ruben!
2nd: if the highlighted statement is about getting a slide-in truck camper, there is a wealth of knowledge I've gained over several campers across 5 or so trucks... Feel free to let me know if you are all good in this dept. or could use some pointers...

Thanks Scott, could always use advice. I've always liked the pop up style campers just because they are lighter and don't have as much wind resistance but since I have never owned one I don't know how that would function in winters or under rain or heat when I would need AC. Originally I was looking for something minimalist just so maintenance is low but I would like to hear what you recommend. Also what is a good truck setup?
