Hey looking for some more help I have a 95 f-150 with 5.0 and a automatic transmission when I am driving at below say 40mph up hill and just giving it enough gas to maintain speed the truck will sometimes shutter and shake for a brief time unless I let off or accelerate then it immediatly goes away any ideas what is causing it?

 

Could be some gear issues. U-joints, transmission fluid low, torque converter sticking, many things. How long has it been since you did fluid changes? And also is the check engine light on?

 

I totally agree with Boogerburns. My truck did the same thing. Changed the filter and fluid in my tranny and it quit doing it.
