4L60E Performance
 

Jet Billet Powr-Servo 2nd gear for the 1-2 shift 700222 - $60

Sonnax HP-4L60E-01 Performance pack - $100

I had the wild idea of installing these into my Astro van to improve the 1-2 shift and hauling, but it's since dropped in importance as I only deliver in it. My diesel S10 project needs funding.
