SMG to 6MT Conversion

[wsybert]

For those who have done the wiring as mentioned in the original post (with gear position switch connected), it says, "Next connect the ground connector from the SMG ECU to the DME pin 20 at connector x60002 (24 pin black connector) next to the 9 pin power connector on the engine DME. Note that pin 20 on the DME is blank, and you will need to disassemble it and insert the wire with a female pin that will click into place."

Is the original poster referring to the brown ground connector wires, circled in green, this photo:
So I am suppose to connect any brown wire, circled in green, to the blue pin 20 wire at x60002 circled in green?

Thanks in advance!

Perfect timing on this question... this is where I am on mine as well. Subscribed!

Anyone in/around OH/KY/IN/PA/MI that wants to help me with this? Willing to travel farther too!

subbed! Very detailed DIY.. thanks to the creator..

Without a car lift this would be a nightmare.

just did it w/o a lift, really not that bad

Does anyone here know why the OP used this method for wiring the pin 2 clutch switch(to pin 13 wire on SMG ECU, then ground wire from SMG ECU to pin 20 on x60002)? Other DIY guides wire pin 2 directly to pin 20 on x60002 - hoping to find the reason why and possibly a solution to my cruise control not working 🤔

He had a quote a few steps down...
"*Note that it is NOT necessary to do anything with pin 2 on the clutch switch in order to get the car to run. This connection is purely for the function of the cruise control in conjunction with the gear recognition sensor that was installed in the tapped M14 hole in the transmission. Also note that even wired correctly, your cruise control will NOT function until the car has been recoded with the proper 6MT tune."

I used the same shifter and rod. I don't seem to have any slop in any gears. I'd guess it's not an adjustment but something that's worn.
Does yours center between 1st and 2nd or 3rd and 4th?

I adjusted it so it centers between 3rd and 4th and its not a slop problem I'm having. It's just that when the car is driving and I'm shifting from 1st to 2nd, I get a loud clunk sound coming from the tranny area. It's strange, doesn't happen in any other gears and doesn't happen when the car is off. Can't be the guibo either since I just replaced that.

I just finished the swap yesterday and used an RTD shifter w/ a DSSR. I get a pretty loud metallic sound coming from the transmission/linkage area when shifting into second gear. Does anyone know what this sound might be caused by? No other gears make this loud of a sound when shifting into.

Could what he did at 14.55 in the video be the solution to shifter slop? Sounds promising and that thing did look solid.

Oh cool. I actually did this when I did my swap because I just could not get the manual pin into the hole. It seemed like my SMG bolt had, in the past, been tightened a little too hard and the aluminum hold had warped every so slightly such that getting he manual pin into the hole was now totally impossible. So I just re-used the SMG bolt. I honestly see no reason why they don't just use the SMG bolt on the manuals to begin with, that pin thing sucks.

Also, cheesy nostalgia: Man, every time I see this thread bump back up to the top I'm reminded of how much of an adventure this swap was. Was my second time really working on a car (first was a clutch job on a MK1 Audi TT), and I've learned a ton since then. Can't believe it's been 2 years!

I've been chasing a sloppy shifter ever since I got my car. Replaced all bushings multiple times. Latest thing I've done is replace all detent springs in the transmission and upgrade to an AutoSolutions autocross SSK. There was no slop between the transmission and shifter carrier even with the regular pin. There's still about 10mm of side to side play in my shifter.

I've basically given up now and am pretty certain that all the slop that's left is internal to the transmission. Looking at pictures of the bellhousing, there seem to be gaps between the detent bearing and the detent pins, which is potentially the source of the slop. At this point I'm just planning on swapping in an E92 335 transmission whenever I've run out of other things to do.

(Rant over) I you've got slop in that connection though, the SMG bolt thing might be worth doing. It'll also get rid of that stupid pin lol.

I'm a subscriber to this channel on youtube and they released a detailed and well filmed/hosted video on their SMG to 6MT conversion. I really like these guys and I thought the video is great.

I'd love to get my cruise working also. Bump for any advice on this.
