Good morning i have a 2000 Chevy Silverado rcsb, im in the process of swaping trans and i saw that my 4l80e didn't come with the adapter to go into the np243 32 spline case I got from marketplace, so neither the 4l80e or tcase came with the adapter, but i have my stock tcase adapter that came on the truck from the 4l60e and np243 case. will that work or is the 4l80e adapter different? if so does anyone have the part number?
