Im new to this site,bought an 05 limited with 26000 miles on it in april of this year. Ocassional I get a stumble it can happen at any speed, and has done it maybe 3 or 4 times since I have owed it, it now has 33000 on the clock. I gues My ? is is this the transmission or the engine? Also when the transmission is shifting up through the gears when it gets to 3rd it seems to go directly into 5th with just a blip in 4th,you can feel the engine lug when this happens. Its seems like 4th is not used very much,even when I manually take it out of 5th on the highway it goes right to 3rd is this normal? There is a big difference between 5th and 3rd,why won't it go into 4th?
