Default 4l60e downshift bang fix

there are a few kits that fix our autp transmissions that bang when downshift.
going from 3rd to 1st or 2nd delay that clunk/bang into gear
Does anyone else have this problem
Has anyone installed a kit to fix it and did it work
This is my only gripe with my car.
Thanks

I'm not a tranny tech, but that sounds like an internal leakage or pressure issue. These guys may have a part to address your problem http://www.sonnax.com/

Might want to try one of the transmission forums if no answers at CF
