Question about 1990 Cadillac Deville

1 Answer

1996 Cadillac Seville started shifting hard all of a sudden

Yesterday, at lunch, right out of the parking lot, the transmission shifted hard. Almost violently. And again from, I think, 2nd to 3rd. Since then, if I accellerate a little faster than normal, the violent shifts occur; but, if I accellerate slower, more normally, there are smooth shifts in all gears. Occassionally, when stopping, once the car stops moving, there is a down shift that is harder than you'd expect as well.

I checked the fluid which was a little low; but, after topping off, there is no change.

    i have the same problem with my 1987 seville seems like after i had the transmission rebuilt it was fine for a few months now it shifts real hard from 1st gear to 2nd the rest of the gears are fine and just like you said as you come to a stop and your shifting down to the first gear it's a real hard shift that kind of jerks the car

The pressure control solenoid needs to be replaced. It"s under the side cover on the transmission on drivers side. Not a simple fix at home. You will also need a side cover gasket. The transmission does not need to be rebuilt.

1991 Cadillac 409 engine won't shift out of Park


Lets start by checking your brake light switch.
Your car has a switch on the brake pedal that not only makes the brake lights come on, but also tells the transmission it can shift out of park.
This really may be 2 separate switches, but should be under the dashboard and both should "open" when you push the brake pedal down.
Take a good flashlight and look.
The switches are small, about the size of your thumb, and both should have 2 wires attached to them.
Be blessed.

Sounds like an internal problem. To be sure you will have to drop the transmission pan and check the color o fthe fluid. It should be pink. If it is white then you are going to have to get the transmission rebuilt.
