Thread: New Hilux Auto Transmission Shudder?

Question for new Hilux owners. Got a new work Hilux SR Prerunner (2WD) auto that has a sort of gentle shudder (or more of a pulsing feeling) which is very noticeable when doing exactly 50kmh around town. Done it from day one - has about 3000km on it now - I thought it may have been a settling in thing but not the case. Does it most the time - but not every time? Anyone struck this with their Hilux or heard of it? Wife and kids can feel it from passenger seat. Surely not a "characteristic" of this vehicle? Thanks in advance.
