converter diff?
 

Doeas anyone know what is diff between 126 250 2302 and 126 250 0902 torq converters? They look the same but something causes the diff part #.

Well, a T.Q. is generally set-up for the specific engine it was intended for....

As to just What the difference between those two are, I have no idea, but guessing they are from different engines fitted to a W126...;)

The third set of digits (the 23 and the 09) are usually used by Mercedes to indicate revisions to a part. Often, parts with different revision numbers are interchangeable.

EPC shows the 09 and replacing 00 and being replaced by 16. It is used with the 722.3 transmission in model designations 300, 307, 308, 309, 319, 320, 322, 345, and 346.

EPC says that the 23 was replaced by the 722 250 22 02. It was also used with the 722.3 transmission in models designated 303, 315, 317, and 321.

I don't know what the model designations mean. Perhaps someone else can help. Your two torque converters may be interchangeable but also have ifferences unknown to me.

Stall speed a factor?
