Been there, done that. Planning on posting the wiring tonight for a guy on another forum.
The basics... have the axles on hand. (I think only the driverside is different, not 100% sure as it'* been a while. Have a pcm with the 97 HD programming in it to handle the change. Automatically use an HD trans. Pull your trans, put this trans in place. Block the vacuum port to the old trans. Take the 7 wire connector, and move one wire at a time to a 4T65 connector, then add 5 more wires into the pcm and have a nice trans.
The 4T65 runs cooler, has a better pump that is suited for the higher rpms. And overall tends to outlast the 60 when pushed. The 60 is known as a great trans because the motors pushing it, weren't pushing all that hard. My choice is the 65. but I'm biased.

okay, ill have to convert the only 4t65e in the junkyard to HD, but its only $100 for any trans. also LSS'* came with the 4t65e HD in 98 and 99, so if i could find one of those pcm'* would it make it easier ?
thanks

For someone doing the same swap. Does the PCM have to be re-programmed to tell it it has a 65 now or does it "learn" the new trans on it'* own. I already have a 97 pcm but a 4t60 trans that I'm swapping for a 2000 65-HD.
