IMHO I wouldn't worry about getting the trans temp any warmer unless you live in ND or Northern Canada in the winter, then I'd think about it. Especially with synthetic fluid.
I know the 175F number is optimum for the fluid. 180F is required to remove moisture content. 80F or above keeps torque converters happy. I think I saw 160 something on your OBD, should be plenty warm, especially for synthetic. I also have no idea where the temperature sensor in the transmission is. The predominance of the heat is in the TC, and I'm guessing that fluid exiting the TC would be considerably higher.
I'll be lucky if I'm at break even or possibly a bit upside down after paying for another transmission, compared to the retail value of an R title low mileage pilot. Unlike you, I did none of the work.
If it were mine and not my wife's baby, I'd drive the current trans till it was fried, or the fluid changes free it up, assuming the valving, or journals are gunked up. For the time that I drove it while malfunctioning, I was able to coax it into locking up 5th gear. Or maybe its mechanical? Not knowing, if its worn, bad clutch springs, assuming these clutches have springs. I just couldn't let her drive it and get stuck somewhere. or limp home at 30mph. Bit the bullet and bought a reman.
My wife loves this Pilot, and as long as I can get the transmission under control, and not suffer any MIF's (maintenance induced malfunctions.) with the transmission swap, I'm hoping to get 10 ish years and130k+ out of it, and run it till it dies.
We had a 2007 Accord V6 AT that had judder issues that started at 8k miles. I took it back to the dealership to troubleshoot, 2 Z1 fluid changes didn't help. Went to a local trans shop, They actually did a flush somehow without damaging the trans pump and I think they used Castrol. The problem disappeared immediately, we ran it till around 200,000 with only 1 other fluid change. Not a single problem. At the time I thought it was an anomaly and not the norm. In fact my neighbor bought it and is still driving it. Probably has 230k on it now.
