If anyone has done a 4l80e transgo kit or something and still has them laying around let me know.

No. All I really need is the small oem bumper spring to go with my sonnax boost valve kit. The sonnax 4l80e-lb1 kit just comes with a stiffer larger spring but you're supposed to use the oem smaller spring. Just whatever one came out of your valve body. I'm not sure if they used different colors throughout the years but it really doesn't matter.
