I have a mercury villager 1996 model. it got an automatic gearbox. Now when the car shift gear, especially when the car shift from 1st to 2nd, the whole car will shake. And also, there is a very big delay between shifting with the rpm going up to 4000 , so if I don't let go of the gas at 3500 rpm, it will just rev up the engine.
what is the problem.
