Question about 2004 GMC Sierra
Transmission shutters and shifts up and down between 40 & 55 mph. It does this with cruise control on and off. It seems to smooth out past 60 mph but still feels a bit strange.The truck only has 24000 miles on it.
I too have that problem. I own a 2005 GMC Yukon. Shutters between 40 + 55 mph. I thought for sure the stumble I felt was a plug or coil pack because it only does it under a load. With A/C on the whole truck shakes! But it wasnt the plugs or coil packs. Answers anyone?

Try changing the fuel filter. I think it's starving for gas and the transmission can't decide what to do.
