The space shuttle has had even more years of development, but neither has become highly reliable yet. I know of Honda's recent transmission problems but haven't heard of Toyota's, so do you have any proof to back up your claim? A TSB itself is not proof; show something like longer-term numbers from Gelco Leasing, Consumers Union, or J.D. Powers.
If there had been just 1 fluid upgrade, then Chrysler would still be at ATF+2 (7176d), not at ATF+3 (7176e), +4, or +5.
