My wife and I just encountered a problem with our van. The faster we go, (especially highway driving) the vehicle shakes and it feels like the whole van is going to fall apart. We just recently had the transmission replaced but I don't think that is the problem. I would appreciate any help. Thanks.

Typically a high speed vibration is a tire balance problem, but it would be wise to contact the shop that did the tranny in the odd event it is related.

There may be a steering part, wheel bearing or wheel loose.
