4k tranny?

[fahrvergnugen at cox.net (David Utley)]

Before a certain date, which is the number stamped after the '4K', you will
need to have it done for a clearer state of mind.  However, I don't know
what that date is.  IIRC, German Transaxle in Bend, OR., knows and can tell
you (do a search, you will find the number)...  BTW, that date would be day,
month, year, in that order...
