Default Brake system question?

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?

nobody has a guess as to what might be wrong, also when you take the car out of drive before i come to a complete stop it doesnt do it, so it has to be an issue with the tranny, or is this normal for bonnies to do this

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!

rpm is normal at idle, and it does it at every stop, if im going slow it wont be as bad, but if im going at higher speeds and try to stop quick its really bad

Kind of sounds like the lock-up feature of the torque converter isn't disengaging all the way. If it stayed locked up, the engine would stall but from the way you describe it, it is staying partially engaged.

so does that mean the converter needs to be replaced? or could it be fixed

To my knowledge(but then, I'm no expert), they can't be repaired.

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
