switching direction
Want to know something funny? You changed yours to how mine started. Mine spun the wheels backward while in first gear, and I got panicked. So, I changed my wiring to how yours started, and it spun the right way. Can we officially add VW aircooled engines to the weirdo list like Honda???

I think it's how the motors were designed, not the car transmissions that was the problem.
On my Metro - if I spin the tranny input shaft clockwise that makes the shaft move clockwise towards the front of the car. To match that, the motor's shaft needs to go counter-clockwise as viewed from the driveshaft end.
I don't think there is a default on the external wiring of a four-power-post series wound electric motor to indicate which direction it spins.
Do you have to spin the VW tranny shaft clockwise or counter clockwise to make the wheels go "forward" in a forward gear?

If you are looking into the bell housing, spinning the shaft clockwise in 1st gear makes the car go forward.

Yep, your transmission is "normal" then. It's definately that the motor can just be wound in different ways to make them spin clockwise or counterclockwise.
Good thing for those extra two posts! I wouldn't be real happy with my car having 5 reverse gears and only one forward!

I like the last shot of the armature free spinning on the transaxle. Don't knock it over!

As a side note on the VW transaxle; you can swap the diff around to reverse the drive direction. Very common mod on Mid Engine Sand Rails + Kit cars using VW TransAxles.

So if you were doing a VW to electric conversion and had a motor that ran the wrong way, you could just flip the differential!
Cool.
