The sheet I attached is one of many online and shifting at 6000 your not pulling anymore.

but when shifting at 5400 rpm where does it fall back to in relation to shifting at 6400? I was always taught to shift slightly past the peak so rpms drop back down into the heart of the powerband when it hits the next gear.
give it a try shifting close to redline on the same day and report back if you don't mind and have a chance. this is interesting because your results are very good...
I have noticed vids of the auto seem to have the shift completed by around 6000 rpm...and i thought it looked early...hmmm
as far as the axles go...its a manual...tale as old as time...good luck. may want to look into aftermarket axles if it keeps happening. and if you add hp or go even more aggressive tire forget it. go aftermarket
