I am having problems with my suburban. When I am going over 45 mph my transmission jerks and jumps. It seems like it is trying to down shift for a moment and then it's fine. My rpms don't change. It happens when I give it gas to speed up or give it enough petal to maintain a speed over 45 mph. I don't notice it when I use the cruise control or give it the full petal.

 

Any help you can provide to troubleshoot the problem will most appreciated!

I heard that is could be a bad TPS. I haven't had a chance to check that out yet. Is it possible? Or, could it be something else?

 

It is indeed possible, nut when my tps went bad, it jerked into every gear like crazy hard.
