MTA New York City Transit New Flyer XN40

So. Having experienced driving with the ZF Ecolife transmissions, I can definitely say I'm not a fan of them.
This one had some odd sound effects going on which while noisy, really lets one hear the odd shifting patterns these transmissions have. Not a fan, acceleration is slowed down as second gear gets shifted through in a hurry. It gets worse when there's a load.
