When braking from 50 mph or 40 mph coming to a stop my car jerks and it’s very hard to stop it uncomfortable hesitation, Jerk, or lurch. Almost caused accident twice where I couldn’t stop the vehicle this is very unsafe for me and my family also transmission downshifts and up shifts are really hard in this vehicle

AT 25 - 30 MPH AND AT 45 - 50 MPH THE CAR SHAKES VIOLENTLY. I TOOK IT TO THE DEALERSHIP FOR A DIAGNOSTIC. THEY SAID THEY KNEW EXACTLY WHAT IT WAS. I NEED A NEW LOWER AND UPPER TRANSMISSION. THAT IS THE RECOMMENDED FIX. THAT IS SOMETHING THAT HAPPENS TO CHEVY TRANSMISSIONS AND THE COST IS $5400. IT SEEMS TO ME THAT IF THIS IS SOMETHING THAT GOES WRONG ALL THE TIME, THAT'S A PROBLEM THAT I DID NOT CREATE. MY VEHICLE IS WORTH LESS THAN THE COST OF THE FIX AND I STILL OWE MORE THAN TWICE THE COST OF THE FIX.

WHILE DRIVING AT HIGHWAY SPEEDS (65+ MPH) THE INFORMATION CENTER WILL DISPLAY 'REDUCED ENGINE POWER' AND CAR WILL DOWN SHIFT AND ONLY REACH 45 MPH. CAUSING CLOSE TO REAR-END CRASH. YOU HAVE TO LEAVE THE HIGHWAY TRAFFIC IMMEDIATELY AND TURN OFF ENGINE. RE-START ENGINE AND CONTINUE DRIVING. IT HAS HAPPENED TWICE NOW. SEEMS LIKE A SOFTWARE PROBLEM. *TR
