but I had another guy on here tell me that the trans changed in 2002 and the input shaft to the torque convert is not the same and this is my 2nd one I put in and they just don't work right! 2nd one this week!

The 2003 used one transmission, the 4L60E. 2000 had 5 options, -700R4/4L60/4L60E/4L65E/4L70E

If you have the 4L60E, 4L65E or 4L70E the 2002 transmission will work but you will need the original torque converter for that transmission.
