Quoted from Bugsy:
From my experience, post transfers can be done on a lot of games, and other games it's not so easy. However, each game is different.
Not only each game, but each physical pin of the same game will often post transfer differently, especially on older titles where there's a better chance the flippers have been rebuilt. It depends on the flipper rubber, the angle of the flippers, how far the flippers travel when flipped, the strength of the flipper, the distance between the flipper and the sling, etc. Lots of factors.
If you've got a pin where the post transfer doesn't seem to go anywhere, and just stays put on that flipper, then you need to get the ball to roll up the flipper a bit, and then post transfer.
You can also alley pass / inlane pass / Shatz on many pins where post transfers aren't working, and you either can't tap pass or haven't developed tap passing as part of your flipper skill repertoire.
