Quick Update... After getting the transmission flushed and all fuilds switched over to Amsoil Signature, the truck does seem to shift and ride smoother.... Could be placebo, only time will tell.
The mechanic working on it did call me and tell me that during the road test before changing fuilds they noticed the following ( I had him write it down in case I need to take it to the dealership in the future, I can give them specific info.):
"During the road test the pulse width modulated torque converter clutch engagement seemed to be revving a little high, never fully engaging at 100% engagement, and sometimes fluctuating 50 to 100 RPMs for seemingly no reason. This was not enough to trigger the diagnostic trouble code, but did seem and feel a bit unusual."
Also, after changing all the fuilds, he also told me the ATF that came out wasn't dirty or discolored, but did smell a little on the burnt side. And also that the front diff was about 1/2 a quart low of fuild... Wanted to know if I had it worked on previously, and I said nope, only has 24k miles on it, must have come from the factory that way. So there's that.
Anyway, will continue to update as needed.
