It's 6043-48 that are likely the problem given their 5 year stint on the X9 & X10.Actually 45-47 aren’t that bad considering their advanced mileage.it’s sometimes a bit of a lottery as too which ones are reliable and which ones aren’t.
No doubt 6084-86 will replace 6045-47 with 6043-48 then probably either going on the 25 or perhaps the new 47/47A. Obviously GNE should still have 6001, 6049, 6050, 6099, 6160 and 6377 available as Riverside decker spares if needed.
Transmission faults, overheating problems, eminox issues, take your pick, that’s alongside the more day to day problems such as coolant or air leaks, belts/alternators/etc.
None of these issues have been traditionally addressed by mid-life refreshes in the past, which on the whole have been concerned with making the outside and passenger areas ‘pretty’.
