I'm going to look at a 2003 4.4 this weekend. Looks to be a nice car, so will report back after I've looks at it.

A few cars I've seen advertised have said they have transmission problems. Light in, and it either needs a gearbox replaced or a sensor... They don't offer much information other than they can drive the car a short way before it goes into limp, low power, mode. I'm not considering these cars in my search, but was curious to see if this was common, and what I should watch for, if anything, when I'm looking at cars. Any advice on this one guys?
