Der TK unterschiedet "bis Feb88" und "ab Feb88".
das koennte etwas damit zu tun haben, wann die Aenderung von 8-Pin auf 7-Pin Schaltkasten stattgefunden hat, obwohl das auch wohl nicht so eine saubere Trennlinie hat. Aus den Schulungsunterlagen von ATSG aus USA:

The Electronic Control system was first introduced in 1986 and was incorporated into the totaly hydraulic 4HP-22 unit produced by ZF. It combines the hydraulic control of forward and reverse gear engagement,
with electronic control for automatic upshifts from 1st thru 4th and automatic downshifts from 4th thru 1st gears.
Three different versions of valve bodies have been used on BMW vehicles, with minor differences between them

The 1st version, designated Early "E-7", has 5 solenoids on the valve body, was introduced in 1986 and used up thru 1989. This version includes a solenoid for reverse lockout.

The 2nd version, designated Late "E-7", has 5 solenoids on the valve body, was introduced in 1988 and used up thru Mid-1989. This version includes a solenoid for reverse lockout.

The 3rd version, designated "E-9", has 4 solenoids on the valve body, was introduced in Mid-1989 and used up thru 1994. This version uses a shift solenoid for the reverse lockout function.

Die Zeitraeume sind jetzt fuer USA, muss nicht mit EUR uebereinstimmen.
