Gearbox Type

[tel76]

On the left hand side of my Automatic transmission is the data plate ,on this plate is the following information,GETR TYP GA 280 SE,  LFD No 01972*F.
Is this the correct transmission or has it been changed sometime in the past .
Thanks in anticipation.

Get the data card from Mercedes (plenty of posts on that, use search), it will give you the number of the original gearbox to match against what you have listed.

W113 series, 16 bolt pan, K4A025, automatic transmissions


The early version of the K4A025 ( 16 bolt oil pan) and the later version also type K4A025 (16 bolt also) is physically the same but has a slightly different valve body in the transmission. This later version of the K4A025 is identified by "GA 280 SE" label instead of "230 SL-E". Both these units are basically the same and are interchangable.

The early K40A025 (230 SL-E) was used in models 230SL, 250S (up to chasis #3651), 250SE, 250SL, 250S/8.

The latter version K4A025 "GA 280 SE" was used in models 280S/8 (early models only), 280SE/8 early models only), 280SL/8 (all), 300SEL/8 (early six cylinders only with).

A new K4C025 (4 bolt pan) replaced the K4A025 transmission in all the later models except for the W113 which kept the (16 bolt) K4A025 until the end of production.
