Auto Trans issues on the highway?
So this has been a problem since I got my truck, but I have always just assumed it wasnt anything wrong per say just how mhy truck is.
While on the highway for the most part, especially going up hill, if I give it too much gas too fast, the transmission basically slips and its like it tries to downshift and shift back up at the same time and the whole truck shakes, like it choking on gas or something. I can make it do it at lower speeds if I stomp on it. But basically I can only give it gas o a limit. It really isnt a problem until I am on the highway, and it is really hilly here in the upstate of SC and so I dont use cruise control much because when i go up a hill it will slip like that, and this makes me think it is a problem.
My lil bro, who is a chevy guy mind you, says its some sensor in my rear diff or something that tells my trans when to shift and how.
Anybody else experience anything like this? Would an Xcal tuner help? Or is this a real problem?
