003 Automatic transmission refresh/rebuild Part 1 - Final Drive

[Wildthings]

Look for a letter stamped on one of the three mounting bosses. That is the code to tell you which torque converter you have. Otherwise they all look and fit the same. If you get the wrong code TC, say the one for a 412 it will give poor performance in a bus and likely burn up the transmission quickly.

At a minimum you want a "D" torque converter, but preferably a "Z" or and "H". IIRC the "Z" was used in the last year of the aircooled Vanagon and VW recommend that it be used as a replacement for the earlier aircools, while the "H" was for the later 2.1L watercooled Vanagons and had the same high stall speed as the "Z".
