4HP22 or 4HP22 EH will fit in both E34 and E30, IIRC. I'm not sure if the support brackets are the same.

Hi, the tranny for the e30 I believe is not electric and has a kick down wire, the one for the e34 is electric, so it has a brain. Also the output is different since the drive shaft is different.

They came in both. I think it was the iS that came in EH or electronic. Mine has S/E/321 switch.
