I am looking for the transmission pan torque specs for the 06 Buick Lucerne 4.6l with the 4T80E transmission.

 

Not sure torquing is necessary. By snugging opposite sides one bolt by bolt and moderately tightening one bolt and next in a row- pan should be just peachy.

Good idea to put a drain plug like for oil in those things if your good at soldering. Maybe Buick already has? Same difference with tires, nuts always good and tight but can remove without stepping on jack handle to even loosen.

If installing heads and gaskets by all means follow directions. Don't mix up foot pounds with inch pounds as bolts can be snapped off on occasion.
