when i apply the brakes and just before the car comes to a complete stop, it leaps forward, thats the best way i can explain it, its not a smooth stop, feels like the tranny is shifting into a lower gear might be a better way to explain it, anybody have an idea of what this might be?

Sounds like your transmission is somehow shifting back into first gear too hard or too slow,possibly a torque converter issue?!?......is your idle-stop speed set too high??,....does it do this just when the transmission isn't warmed up/cold ...or all the time ??,.........pretty strange problem!

well see the dealership does get paid for that job.. GM pays that dealer for the work.. but they are just damn lazy and dont want to do the work the right way they first time. I've been told by GM HQ that they get paid for warranty work. they just want the money and not to solve your problem. i just feel with todays technology, we shouldnt be having a lot of these problems we have. than again.. we ahve a lot of stupid people manning the machines that make our cars..i guess.. IMO
