As to thrust, the tranny is already set up for thrust (witness the amount of
polished shaft sticking out from the cutlass, at rest, the amount of thrust
forward taken up by the engine mounts and whatever else being that polished
amount - on ours, about 1/4")...

Auto trannies that I've had my hands on deal with the thrust by a splined
shaft at the tranny,

Auto trannys don't have to deal with thrust, suspension components do
that.

Speaking of thrust however, this is a good time to check that your
shaft is firmly locked into the coupler with shaft indentations and
safety wire on the set screws. More than one boater has had the
experience of reverse thrust taking the shaft out of the boat. You'll
want plenty of reverse thrust to properly set that new anchor of
yours.
