Harsh downshifts (zf8hp70).

[alex3dworld]

I had this downshifting issue in my car for a while, it was so annoying but after the software update have been done ( on first service) the car is driving completely different , the issue 99% gone......

so i noticed bunch of guys from Australia talking about software upgrades, is that something unique for Australia? sorry im new to the grenadier and still trying to figure the cardinal points here. lol

The Down Under crowd started receiving vehicles a full year before North America. The early vehicles were a little less polished, shall we say. You'd have to ask @Red pepper directly but with a forum join date of 2021 I assume he may have been through several updates.

@255/85 do you use manual mode at all?

@Zimm might see if the transmission adaptations can be reset. Mine is under 2k mi and shifts pretty smoothly into 2nd and then doesn't go to 1st until almost stopped. It kind of reminds me of the ZF 8HP75 in the power wagon w/ tow mode on in the lower gears.
