Anyone have their TCU tuned/modded?
Mine seems to constantly fall out of lock-up under 80km/h. 2-3-4 changes are all "sloppy" with it taking at least 3 seconds after shifting to finally have the the Torque Converter lock out which is definitely messing with the economy.
Even in manual mode it'll fall out of lock-up with anything less than about 20% throttle. More throttle and it will lock and use the engine torque to pull.
It's got 155K km on it and the trans with serviced (new fluid and filter) at 150K.

Have all the updates been done by an Isuzu dealer?

Have you connected a scan tool to see if there is any codes present/pending?
The throttle position sensor on the throttle body may be a bit dicey and not always connecting and giving trouble in the throttle position where it has been used most of it's life. Some are removable and cleanable and an inspection of the carbon track path may reveal undue wear or it is dirty. Not common but possible.
If removing it, firstly positively mark it's position where it is bolted so you can return it to the same spot.

I would look there first of all.
