Hello,
The early automatics had the opposite linkage geometry with the shift pattern "park" at the top (forward position). The easiest identifier of these early automatics is to look at their oil pans. These early units had a "16 bolt oil pan". Later transmissions had a four bolt pan, then a six bolt pan.
All the "16 bolt" oil pan transmissions had the shift pattern at the bottom. So this means all the W111, W110, sedans used this arrangement along with all the W113 cars. Only the early W108, W109 sedans, the early W111 cpe and conv. and W112 cpe and conv. had these early 16 bolt oil pan automatics.
I am not aware that any of the "16 bolt" transmissions were used in the W114 or W115 cars. I suspect that the unit you have is from a 250 S or SE sedan W108 chassis or an ealy W11l1 cpe.
