9HP48 gearbox problems

Hi , I am new to The evoque world but not new to the motor trade. I’ve had my evoque for about 3 months now and am becoming increasingly frustrated with the gearbox which I feel seems to hold in 2nd before going into 3rd with a bit of a kick . Ive reset the adaptive values with my Snapon solus ultra which didn’t seem to make any difference so I have taken it to my local dealer who have checked for any software updates and carried out a reset and relearn of the addaptive values . I have been told that this hasn’t improved it , the next step is to change the oil , this seems a bit of a mine field as the OE oil is LR023288 which on the ZF website cross refers to lifeguard 8 but on ZF’s website they list lifeguard 9 for 9sp and lifeguard 8 for 8sp !! As both these oils are pretty expensive I was wondering if anyone had any insight into these oils . I have also spoken to a specialist who have the ability to flush the transmission which cannot be done with a simple drain and refill , they use a Q8 product but need to check into wether it is suitable for the 9sp transmission . I am just wondering if anyone has felt an improvement with an oil change or is the gearbox a bit of a flawed product as the more I read about them the less confident I feel !! The evoque is a 2014 model which is very early for the 9sp transmission but has only covered 62000 miles so along way short of really needing a fluid change , any tips or advice would be welcome .
