NO! the Montana is a front wheel drive minivan and the firebird is a rear wheel drive, even if they were both rear wheel drive for some reason, the firebird engine would shred the wimpy minivan trans and it would be just wrong to put a minivan trans in a firebird.
it is located in the gas tank.
I have a 1996 Firebird and it has 4. Two in the manifolds and one before the catalytic converter and one after.
backside of the intake manifold under the hood cowl.
should be under a cover passenger side back of the car
yes it will pontiacs are interchangable from the years 1993-1996
in the trunk or under your back seat
well you can change the entire rear hatch with that of a trans am's but I dont think it would be worth the the money to convert the car into a trans am style car.
on the left hand side frame rail approx under back seat
Bad resistor on key? Bad sensor in ignition lock?
