Transmission warning light

[NZ00Z3]

Hi Peter

Light Bulb moment: have you checked the LVVTA requirements regarding your gear box change? Does it need certification?

Look up section 13 in http://www.lvvta.org.nz/documents.html#thresholds.

Doing a 6 speed change requires a modified drive shaft front section (gear box is longer) and you may need a different transmission cross member, so you will need drive shaft hoops for each section of drive shaft etc and a LVV certification.

You guys in the UK have it made with what you can do with your car modifications. Here in N.Z. there are safety limits that we have to work within.

Hi Murray, this is what I mailed to LVVA and what I got back. In this case I was assuming that I would use the 5 speed gearbox:
Good morning,

I have read on your website that a gearbox conversion requires an cert. My BMW Z3 has blown up it's automatic transmission, and the cost of rebuild one is as high as a auto to manual conversion.

If an MTA garage is doing this conversion, and they use only original BMW Z3 parts, just the way how a factory new Z3 manual was delivered from factory, do I still need a cert? Because the car is then practically the same as a original manual Z3.

I hope you can clarify this for me.

Kind regards,
Peter

Hi Peter,

Most of the time this needs to undergo certification, however there are a few vehicles that can get away without it, not due to anything else but the way the Wo F standards are worded. I’m not sure if a Z3 is one of them, but some other BMWs are.

The catch in most cases is that the pedalbox of the automatic car and manual car are different, and as soon as that’s changed, the vehicle legally requires certification. The Crossmember also needs to be the OE item.

The exact wording, which the WoF agents go off is here: http://vehicleinspection.nzta.govt....l/miscellaneous-items/engine-and-transmission

If you run through those boxes, you’ll be able to figure out if the Z3 can be done without certification or not.

Hope this helps.

I was just wondering, basicly it is modifying to original manual, I guess the LVVA will see this differently.

Hi Peter

Good to see you are on top of the LVVTA certification.

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 now I am wondering if I should open the old gearbox if it is truly full of metal parts. Any experience with failed EGS anybody?
