Leaking A904 front seal

"Easy" depends on what work area or tools you have on hand. If you dont have a lift to get the car overhead, only have a floor jack and a transmission adapter that mounts on top of it, you'll probably not get the car high enough on typical jack stands to roll the trans out from under the car while on that floor jack setup. In some cases, If you have a cherry picker / engine hoist, pulling the engine is easier.
The jest of how I have done it ( typical LA )... Remove upper radiator hose. Set distributer cap off. Put the car on stands. Unbolt exhaust pipe collector to manifold bolts. Unbolt to remove the trans tail cross member section, tilt the trans/engine back far enough to get the upper most bolts out of bell housing. Poke the bolts back in the trans support. Thread a cinch strap around the torsion bars and cinch it up tight enough to support the bell housing/front of trans. Remove remaining bell housing bolts. Remove torque converter to flex plate bolts. ( Unload torsion bar at their adjusters optional ) Let the car down and roll it out from under the raised engine if necessary.
