I have a 2002 silverado 2wd with a 4.8. Transmission finally gave up in it. I picked up a used 4l60 from a 1998 2wd suburban. When comparing the 2 transmissions, Ive noticed a difference in bell housing, torque converter, and input shaft. I know the bell housing can swap over as well as the torque converter 'IF' I am able to swap the input shafts as well. Can anyone tell me if the input shafts are interchangeable between these years? Do I also need to swap out the pump and stator?

 

Input shaft and stators are different, think pump covers are interchangable.... I use whatever it takes transmission's or Transtar catalog when tryin to figure that stuff out.....i am sure someone may know for sure though, off top of their head..
