As you all know I smoked my 4L60 after the waite4me tune. I have ordered a new 4L65E out of an 03 SS silverado to take its place. Its going in a 02Z71. Can anyone tell me what all I will have to change to get this tranny in and working?

Thanks

 

plug it in and go a 4l65e has an extra clutch in 3-4 and five pinion planets thats all otherwise no different so your fine
