I have my suspicions,
Not based in any facts, that the majority of the AMR26's gearbox problems are explained as "gearbox" problems but are really PU drivability issues... I think after Newey had the big finger point incident at the beginning of the year, AMR F1 are avoiding pointing at Honda's PU as a cause of problems.
It's not too hard to see Honda messed-up (and by some way). It's also not too hard to see that Aston did as well. The initially unreliable PU and PU installation/integration also limited running, which will have made optimisation and testing extremely difficult in pre-season testing and the early part of the season. On the other hand, there seems to have been a real last-minute coming together of the whole car and particularly the gearbox, which meant little or no installation/integration work before pre-season testing. The chassis and aero doesn't exactly cover itself in glory either. It's a big mess on all sides.
Another point to consider is that it's not like they have a weak PU but everything works together, as well as reliability issues, I'm guessing the shift quality and regeneration strategies are totally immature, and no doubt all the software around PU driveability and coordination with the gearbox is the same. It's probably like alpha-release software (just about barely works).
In the specific case of Barcelona, the gearbox issue
was stated by Stroll as "I had to retire the car because of a gearbox issue; I couldn't get third or fourth gear for the last couple of laps. We'll investigate it further after the race", so this particular case seems likely to have been a genuine gearbox problem, or maybe hydraulics.
