Tranny help This is not an LS based question,But what better place to ask 
This is my sister's S10 Blazer w/126K miles.Cruising in between 50 & 60mph its shifting between 3rd & overdrive with my foot slightly on the gas pedal.All other gears shift fine and it does not appear to be slipping,What would cause that................Paul

Yes what year is the truck. Is it a 4l60e? And is it shifting 3-4 or is it possibly going in and out of lockup?
