Z3 2L automatic transmission failed

Recommended Posts

Hi, 

Just from one to the other minute the dasboard light of my gearbox flicked on. I had to drive in limp mode 30km further to home. At home I was able to log in with Inpa, and Inpa told me that there was a problem with the pressure regulator solenoid valve. Normally I fix stuff myself, but at the moment I just don't have the time for it.

So I brought the Z to a transmission specialist, and he had a look at it. He opened up the pan and found metal dust and swarf inside. The metal parts had shorted out the solenoid valve, hence the message on Inpa. He told me that that a overhaul would cost at least $4000 plus GST. :o

I had to think that over... The next day my son spoke to our neighbour (BMW fanatic) who was at a local garage that morning asking for a quote for an auto to manual conversion for his E36. The garage said to him that it would cost probably around $3000.

That brought me also on the same idea, why not a conversion? The garage said that the conversion of the Z cost probably a bit more. So the latest week I am browsing the net about conversions to manual. The garage who wants to do it for me rather have me sorting out the parts than him. He says that is cheaper to do.

I am doubting between an E46 six speed box or an E36 5 speed. If I converse to 6 speed I can keep my LSD 4.44 and have normal rpm. Later I can go to 3.46 and have a nice cruise rpm. If I choose for a normal 5 speed, I have to change my diff to a 3.46 anyway. Any recommendations here?

My garage gave me two addresses for parts. He pointed me to HellBM and SDEuropean. HellBM mailed back that they only do inhouse conversions and don't sell conversion sets. I haven't heard form SDEuropean  yet (weekend)

I saw some traders on tardme selling conversion sets. One trader is offering a set for $1250, which looks reasonable to me. But when I asked for a E46 six speed it is $3k for the gearbox only. What kind of prices are these 6 speed boxes. What can I expect? 

Are there other (reliable) sources where I can get my parts, prefered conversion sets? Any thoughts about this?

Can't help much myself, you seem to have found as much information I could offer.

A 6 speed box will be mighty expensive, yes. They're out of ///M cars so ///M tax.

A garage has built in a used auto transmission for me, because I couldn't find a conversion set and I need my car to drive. But when he tested it, the same light came on. When he reads the EGS it comes with the following error:

5 pressure actuator
235 No description

and earlier als EGS fault.

Do these EGS fail, or can they fail due to a short circuit in the transmission box? I mean, the transmission specialist to whom I brought the box the first time said it was full of swarf and metal parts. I am normally not so suspicious, but I am wondering if I should open the old gearbox if it is truly full of metal parts. Any experience with failed EGS?
