    Oh also, the tranny is the GM (my anti-Obama brother calls them "Government Motors") 4L30E so it's not one of the ZF units. The Isuzu Trooper crowd seems to have posted generously on how to get the fluid level correct. When it cavitates, it makes no sound, just falls into a neutral state for a moment.
    On the windows, all 4 don't work (and yes they could all be stuck from 3 years) the moonroof doesn't and the central locking doesn't either. So I need to get after the fuse checking.

    Default ...and the verdict is????

    Took her to the CA Smog Inspection station and....SHE PASSED!!!
    No way in creation I thought that would happen first try. Visions of all sorts of reasons for failing. Whew!!! How is that? Her twenty year old catalytic is doing the deed! Incredible.

    Got the fluid topped off with no mess on my driveway (wowzer.) All the rest was just a fuse as suspected and every thing except the stereo is all good. My stereo seems fine, the code entry beeps when I enter the 5 digits but it just stays in CODE mode and doesn't transition to radio. Have tried countless times. Where do I send it to get it fixed????

    So happy on the smog

    Ahhh such a good ending, still waiting for the money shot though!

    There is nothing like the feeling of success against adversity when one finishes major surgery on a bimmer. Def. worth an entire weekend of beer drinking goodness in the garage.

    Radio Code? If it doesn't respond to the correct code, you can follow the various guides around (See shogun's pages for the good oil on that) or just put in a new one

    I recently added a new Nakamichi 625 for AUD$89 w iPod, USB et al to the daily. Works well, except for the am radio of course. JVC have a really nice one (a Ksomething503?) which has bluetooth handsfree as well- that'd be the one I'd go for - its only AUD$159 here. There are cooler radios, but these are usable and do what I need.

    EDIT: Don't forget to post high def engine bay pics!!!

    ... and again- well done it has been a most wholesome journey!

    I changed my radio for an Alpine CDE-103EBT straight in with an adaptor plug from Jaycar it has USB, Ipod, bluetooth hands free and colour change display that can be set to red-orange to sort of match the display of the BMW so it dosn't look too out of place.

    I like the idea of a plug and play on the Alpine w Jaycar adaptor. My kid will dig the USB iPod hooey. Great info. I will dig around for Shogun's tips on the original, but like the Alpine option a lot.
    HAH! I forgot the money shot of the engine compartment - will do that this week since the weather has been so nice. 70's yesterday 80's today. Might even post up a video of the thing running. As the NBA players say, "smoooove"
    "Success against adversity" is a great way to put it. I honest to God am still stunned how smoothly the startup, run in, smog check etc. have all gone. One of the reasons I dicked around for so long putting on the intake is that I was scared sh*tless that it would have major problems and I'd be so pissed off I wouldn't be good company for the family.
    Very thankful.

    The jaycar plug I got was for the e36 so I had to change some wires around but the head unit went in with no problems, there is little room to play with behind the dash so size is important here. I used the wiring instructions from the e34 website and simple matching from the units instructions to set it up and it sounds great with this unit, it has some settings that allows you to set for the best from the speakers you have in your car. Hard to explain but if you search on line for specs you will see. Mine does not stream music from bluetooth that is only for the phone, other units may do that but the phone is clear and very handy.

    As my buddy just brought to our wrenching place a Jatco trans for disassembling and study I started searching for repair manuals and parts lists , the small metal tag on the trans mentions Jatco GB0100E, 4.52.11060 and that did not give any good results in the internet. Then I found the following with google

    Makco sells the ATSG manual http://www.makcotransmissionparts.com/24400E.html
    http://www.makcotransmissionparts.com/manuals.html
    4L30-E is also used in BMW as we all know, so I searched with that and also found our old thread here:

    Not sure if from E34, maybe you know what it is:
    The tag at the end of the tranny : Jatco GB0100E , 4.52.11060
    On the side of the housing there is a sticker:
    JATCO Y OE
    45211 06 YOE
    1421870
    JR 502 E - B GB 010

    wiki: "Many OEM users assign new numbers, and Jatco has switched to a new scheme starting with "J" for Jatco, "F" or "R" for front- or rear-wheel drive. The next digit is the number of gears, while the model series is now two digits sequentially. The model series names do not map directly — although the RE4R03A became the JR403E, the unrelated RE4F04A became the JF403E."

    JR 502 E - B GB 010 : Based on this it would be a Jatco, rear wheel drive, 5 - speed, ????

    Based on that list, probably for the US market (?) http://worldwidepartsoutlet.com/Vehi...le%20Index.htm
