Transmission noise at redline
I always wondered on the Tacomas with the 2rz engines (the only 4 cylinder ones i've ever been in) that when you approach the redline while driving, why does it begin to make so much noise? It is like that on my friends truck too, but it that just from the engine vibrations, a lack of real sound deadening, sloppy tolerances in the tranny, is it actually something else, or what? There is nothing mechanically wrong with these vehicles to my knowledge and I am just curious why they make these noises...so if anyone knows why, tell me!!!!!
