With the gearbox linkage going so smoothly, I now have to do some wire tracing on the granny tranny slush box selector wiring. I have the Euro e30 with the sport auto transmission which has a gazillion wires along with a separate computer for the transmission.
I figured it would be different from the non sport Euro e30's and it is, wiring is totally different, both positions and color codes.

Should not be too much work to sort out hopefully.

Striker, first thing, you have your shift linkage backwards. Youll notice the linkage has a notch in one side, thats meant to face down to avoid hitting the guibo. If it doesn't rub right now with the drive shaft bolted up in third gear, you should be fine tho.

Your wiring is odd to say the least. My best guess is to take one wire from the reverse switch (all the way right connector in the second to last pic) and hook it up to the green and black wire in the auto harness. then hook the blue and white one up to the other. It should bypass the neutral safety and still have your reverse lights work but I'm not 100% sure. Try to find someone else who has done this before or find me a wiring diagram for your car. I only have regular wiring diagrams.

Yoshi, the linkage has been reversed a while now, I noticed it before, thanks for mentioning it though. The linkage has no notch on it either but clears the guibo, will have to check the drive shaft when its in.

I have the wiring all figured out, will post my tests, results and color codes later in case another Euro e30 with sport auto tranny owner wants to do the swap.

Say I found a 1987 325I 4 door manual, will that tranny work with my 1987 325e 2 door auto? IE that sensor thing on the bell housing, also are the drive shafts the same length for a 2dr/4dr?

Hypothedically speaking of course. <.<

a 325i bell housing doesn't have the holes for it. You can probably cut your own.... But I'd find an eta one. I'll trade you but you have to come and get my eta tranny lol.

O.o that's a bit of a trip, granted I do need a vaction though lol.

What exactly does that sensor do? is there a way around? Crap, I find a tranny but it's a no go.

I guess I still can get all the other parts off of it. But the tranny just for when I do find one.

By the way when going through junkyard transmissions what do you look for? How do you know if it's good or bad? Also what parts would be good to take from a junkyard car? I'm guessing pedal setup, flywheel, tranny, any linkage, driveshaft. Everything else to get new stuff or rebuild crap?

Bought an 91 325i MTech vert a few weeks ago with some issues. Many issues but a nice body. May have to pull the engine and would like to do a five speed conversion. I think it will be a lot easier if the engine and trans are removed and reinstalled as a unit. I did not see a reference to where the master cylinder is located. Also would like to get the cruise wired correctly. Otherwise it looks to be a straight forward unbolt and bolt up operation. Looks like there can be some shifter location issues but it seems they can be dealt with while the trans is installed. Hopefully when the time comes you will be close at hand on the web.

Thanks

Ken

Thats the funny thing I never found anything that would disable the cruise control. If you do the relay thing in the post above yours, you have 100% returned the wiring harness to a stock 5 speed configuration. Has ANYONE gotten cruise to work with a 5 speed?

What you mean about the master cylinder? It mounts to the pedal assembly.And what about the shifter? it should go in easily.

and welcome to the boards!
