92 525i 5 speed tranny ID??

[Rigmaster]

Guys,

I've got a '92 525i parts car with a 5 speed tranny- how do I identify which tranny is in there?? ETK shows 2 different trannies, one is E34-specific and the other is also used in E36's... Not sure of the designations, but can someone shed some light on this for me?

Thanks, Bret.

vin specific or by manufacture date?
