A transmission does not suffer from red-lining engine. Engine (and mostly distribution: valves, cams and so) does. You may get a premature old engine by driving continuously that way, loosing vaste compression capacities (and thus significant power), burning oil, increasing fuel consumption and even working at higher temperatures. On the other hand, it burns deposits on the spark plugs, piston heads and exhaust valves, so it is not bad to do it some times every while.
As for the American conception of 4-cyls., it is not true that they need to be very revolutioned to be good. Hondas V-TEC and similar small japs are exceptions. I used to have a european 4-cyl. 2.0L and was able to accelerate very well, very fast and without vibrations on 5th gear from 1.000 rpm.
My newer car, a BMW M-3 E-30, gives 200 HP (DIN; =225 SAE aprox) from only 2.3L. Its red line is 7.200 rpm, and the exhaust is MUSIC all range, but best sound is 4.000/4.500 rpm floor gas. I redline it some three or four times, once every one or two weeks, in a road with a 5 kms (3 1/8 mile) tunnel, stereo off, windows down...: hair-raising!!!. About twice a year, I go rally it to a mountain road with many small curves. The speed is not very high, the revs go high, and the excitement is extra-terrestrial.
She is 190.000 kms old (110.000 miles), but works like a swiss clock, starts always the first time no matter how cold outside, and I do not need to add one drop of oil, because does not burn any, although I change it every 15.000 kms (9.400 miles)
My newest car is diesel, and although it performs good 107 HP DIN from just 4cyl, 1.9L turbo, it is not worth to rev it above 3.500 rpm. Anyway, many "pretended" sporty gasoline ones would like to accelerate as nice as my turbodiesel, when I drive it between 1.500 and 3.500 rpm.
