Hi PB, it would be good to know age/milaege etc but here goes...

When I test drove a Treg for the first time it displayed similar symptoms to yours (if I understand you correctly) - the box appeared 'confused' and 'hunted' between gears seeming unable to decide which gear it should select - this was especially noticeable when going uphill, as you say. Thankfully I've never experienced the same issue with mine but I can understand how frustrating it might be.
I believe the basic elements of the auto-box in the Treg are those from the Audi A8 - so they should be well proven and generally robust. Like most modern auto's, the box has electronic control - hence the opportunity to select 'Normal' (economy/comfort biased) OR 'Sport' (late upshift/early downshift - for better response). The box is adaptive to driver style, so timing for up-shifts changes depending on how you drive but this shouldn't really affect the quality of the change or the box's ability to make a selection. Question: Do you experience the same symptoms when in 'Sport' mode?
It is possible to re-set the box's memory (as Pilgrim recommended elsewhere) "if you wish to reset the gearbox turn the ignition on without starting and hold the accelerator down for 15 to 20 seconds" - so I'd try this first. If this fails then it may be necessary for the dealer to change the software.
Regarding the MFI readout - I have noticed a slight delay in the upshift registering in the display - maybe by a second but that's all.
