Hi I have problem with my car when I go up to hill it doesn't speed up and stays on 40 and also it shaks when I push race so what should I do to fix it thanks

You need to take it to a mechanic to have this problem properly diagnosed. It could be something simple like a clogged fuel filter to a transmission problem. Don't understand the term "push race"? Does that mean when you put your foot on the accelerator pedal all the way to the floor?

It could be your transmission or it could be in need of a tune up.
