BMW Z3 1.8 116 hp transmission

Good to all, I am a rookie here.
I have put this question before but I don't know if I have done it well.

I have a BMW Z3 1.8 116 hp year 96 Type G-18-4E-2

I have a transmission problem and my mechanic does not find the piece they need (originally sell the entire complete group and it is worth 1,700 euros plus VAT plus labor) My budget does not give for this.

I have offered to look for it, but it has only told me that it needs the transmission. Can you give me the referral of the piece or any more detail? I am not very sure of what I am looking for.
Thank you so much.

Good, I definitely have to look for the whole transmission group. I don't know if I have done something wrong, I'm a rookie in this, but nobody has deigned to answer.

Thank you.

Good afternoon, I found it looking for it I have already solved it.
Thank you

Hello.
You could have said what piece you needed, and also as you resolved (to find out all).
All the best

I will answer with pleasure.

What I finally needed was the entire rear group.

Through an advertisement page, "Milanuncios.com" I locked a wrecked car just like mine. I was in a scrapping in Madrid (Ankar tires and workshops) I contacted them, they told me that they had it, I paid for transfer, it cost me 390 euros (Gtos shipping included) arrived in two or three days and the change of the group did it to me in a workshop of Gandía for 150 euros.

Greetings to all.
