2004 yukon xl tranny slipping

[neo297]

Well just wanted to update I changed the fuel filter and it was not broken like the privious one but after replacement my wife says it has not stumbled stuttered or stalled. My driving is very different from hers i.e. mine short in town spurts to work pick kids up at school etc hers freeway speeds 45 miles one way to work along with in town driving. I'm keeping my fingers crossed that it was the issue but it has not acted up since the change2 weeks ago.
