You're welcome, do the following before buying:
- Inspect the rear trans mount bolt hole locations to ensure they're not stripped
- push/pull on the input shaft - you should feel a very slight amount of longitudional travel - if you feel it move in/out by 1/4" or so, the forward drum thrust bearing has collapsed - reject that trans if so
- inspect the input shaft splines carefully - older 4L60Es can have excessively worn splines which will strip and result in a no-movment condition
- spin the input shaft - it will be hard to spin but should not bind or "gall"; should be smooth - watch the output shaft when doing this. If the output shaft is spinning in lock step chances are the 3-4 pack is partially welded to the front ring gear/3-4 clutch hub - listen for a "tin sound" - if you hear it and it's pronounced, thats a broken sun shell hitting the inner case wall
- inspect the output shaft splines - ensure they arent worn/chipped
- spin the output shaft if you can - make sure it spins (will be 3x harder to spin counter clockwise vs clockwise if viewed from the front of the trans - make sure it spins freely without hang up
- put the trans in park then spin the output shaft - it should lock up after at most 1/8 turn
- shine a flashlight into the pan looking for any metal, dark clutch material - smell it to make sure fluid isnt burnt
