Thank you all for your replies 
At least for me it is clear that after the repair I will be extra careful to avoid any misuse of the gearbox because what could be an abused 2nd gear, could very well be a 1st or 3rd, etc.
Hopefully I will not get surprised by something new in the future.

You just want to avoid driving like a gorilla

As noted you don't even have to be "careful." Careful and Abusive are opposite ends of the scale with a massive mid range. Extra careful is off the chart beyond careful. Just don't be abusive.

Transmission fluid every other oil change, or 12k miles max. Gearbox maintenance is important.

Your decimal point slipped. Maintenance schedule for the manual gearbox is 120,000 miles or 6 years. (60,000 miles/3 years "severe" service.) The service DIYers tend to miss is the rear differential which is 30,000 miles or two years in normal service or 15,000 miles in severe service -- that's every other engine oil change since the schedule is 7500 miles.
Gearbox shifts so much smoother when the oil is changed and it takes less than two quarts so mine gets changed at the same time the car is on the lift for the differential change. Getting dirty so get it all done. Honda MTF, Royal Purple SyncoMax, etc.

I've always wondered why the rear diff fluid gets so much dirtier than the MTF.
I know it's half the capacity (0.78qt) of the MTF (little less than 2qt), so it should get dirtier quicker cuz much less volume... but my MTF always comes out crystal clear and like-new, while the diff fluid is always muddy and black, whenever I do fluid changes.
I do it every 30k miles, both MTF and rear diff fluid at the same time.... since I drive like granny, never take long trips, don't track the car and rarely even hit vtec, lol.
Perhaps it's the viscosity (and/or chemical/ingredient makeup) too? ...as the diff fluid is super thick (I use Mobil 75w-140).

GL5 has a different chemical structure/ingredient than GL4
