On what vehicle???
With my Demon it's a 30 min or less job once it is up on jackstands. No power tools involved.
6 bolts/nuts on header collectors
4 bolts on the u-joint straps
3 bolts on the shifter mount
3 nuts on the shift levers
4 bolts on the trans crossmember
unplug the reverse sender switch
4 bolts connect the trans to bellhousing
Slide it out. Easy peasy
