99 CADDILAC CATERA JERKS/TIRES START STUDDERING WHEN DRIVING ON FREEWAY on 1999 Cadillac Catera

When I'm on the freeway or driving over like maybe 45-50 mph the whole car starts shaking and jerking and the tires sound like there studdering. This only happens sometimes and sometimes it drives perfect but it's starting to happen more often. ANYONE KNOW WHY OR WHAT I SHOULD DO ABOUT THIS???

Are there any warning lights on when this happens? What does the transmission fluid look like?

YES WARNING LIGHTS ON...The ABS lights on, CHECK ENGINE lights on, TRACTION CONTROL lights on. As for the transmission fluid I have no idea but will check it if you need me to.

You need to have the codes pulled by a local shop and you need to check your fluid levels. Get in the game and take control. Has the car been maintained? What does the battery look like? Are the terminals tight and clean?
