Hi just wondering what the differences are in the 4hp22 auto boxes? i have a leaky unit in my 87 320i and have a spare from a 87 325i both boxes are 4hp22(not eh) but the one from the 325 has a plug on the gearbox as pictured below:

The 4hp22 box on the 320 does not have this or a wire to connect to this plug so would the box out of the 325 work regardless of nothing being connected to the plug?

the 325 one is a switch able one with electronic kickdown and the switch on the centre consol. The one in your 320i is the non switch version with a cable kick down.

As far as i'm aware they're not interchangable
