transmission help
Your 1998 4l80e might work...as long as your doner harness has the auto pigtail..With that setup you might only need a crankshaft spacer for the converter to fit properly.
If you do need a special speed sensor PATC has an inline one that adapts cable drive to VSS signal...problem is its a slow signal so it needs to be tuned in the computer to read a slower signal for accurate speeds.
