I will look for you. I think I may have a 1999 or 2000 G2500/G3500 5.7/4L80E file. From what I remember those two years use the same operating system. I used the 4L80E van file to segment swap a 4L80E transmission segment into a 1999 GMT800 Silverado 4.3 file. Transmission and ABS worked perfectly after that.
