Default Re: Build Journal - RTD shifter - SMG to 6sp conversion

5-22 - Update

Ok some progress and pictures. I'm now at the driveshaft removed stage and am stuck at exactly what I've been worried about - removing the shift actuator from the transmission without dropping it. As the picture below indicates I have dropped the trans a little bit, but am not letting it and the engine rest solely on the engine mounts, but it still seems like a tight fit.

Would removing the 3 10mm bolts that hold the main smg actuator body to the transmission free up some space to work to get the nut/bolt loose as well as the two round capture wires that hold the gear rod selector with a pin?

Should I go ahead and begin the process of removing the smg shifter mechanism inside and then drill out the 3" hole I'll need for the shifter. That way I have the room to work from above?

There's also the sound deadening material, but pretty sure I shouldn't hack that up right?

It also seems a bit tight to remove all the hydraulic lines - when removing the shift actuator, will all the lines come with or do they need to be separated individually? sorry if i'm coming across as an idiot here, but I really am just figuring this stuff out as I go.

Get the all the hydraulic lines off the car and out of your way. Also, drilling from above won't help you here. Once you have more space it'll be easier. Lastly, the dowel in the gearshift rod joint may or may not be a pain in the ass.

yikes - ok did just as you said - pulled off the 4 hydraulic lines. Also, I didn't originally remove the metal under tray and that was preventing the engine from tilting more to allow me more room. So you would think that would create the space I need, but sadly the nut/bolt that hold the actuator in place on top of the trans and the horizontal and vertical pin holding the gear selector rod are still on.

I've tried using pick tools to get at the pins, and I jiggle the unit to free up the pin. it budges a little, but I can't remove it.

I used a 13mm socket to remove the nut. Is the bolt drilled into the top of the trans mount too? I can't seem to get a 18mm socket on the bolt to pull it. How were you able to remove that? I have tried using a flat head screwdrive against the back end of the bolt to pry it loose, but also no luck.

I'll give this another go today, but if I can't get the stupid actuator off the trans I'll either

1 - dremel it off
2 - remove the bell housing (sadly) and then pull the actuator assembly off clean. Interestingly, the TIS for this procedure does say you don't have to pull the bellhousing to do this job as indicated by this link

Help!

tried to remove the pins and they simply didn't budge, not to mention there's zero room to move these.

tried to remove the bolt holding the actuator to the transmission - didn't budge similar situation to above just not enough room to work it out.

So - will be pulling the transmission...in a few days...

It's more than doable on the car. You must be missing something...

i certainly would be pulling my hair out if this was my daily, but it's not. I'm just pecking away at this job when I have time. I've lowered the tranny as much as it will go the back of the engine is literally against the firewall, so there's no more add'tl room.

I've pb blasted and wd40'd the pins and the bolt - they won't budge.

I know there's at least one forum guy here or on e46fanatics that expressed exactly the same issue and ended up cutting through the rod selector to sacrifice the actuator, but I really don't want to do that.

Also just to be clear I have jiggled the rod selector while trying to move the pin at the same time, but no luck.

If I'm missing something, maybe its any advice you might have that I haven't tried yet...

Update - Tranny is pulled! And yes, the bolt holding the actuator punched right out with a light tap from the hammer and the pins came right out with a light tap from a punch.

I'll have some pictures soon, but I'll be moving on to installing the clutch pedal, drilling out the hole for the shifter in the trans tunnel and putting in the hydraulic lines.

The tranny won't go back in for at least another week, as I went ahead and ordered the clutch bearing, pivot fork, clutch, spring, etc.

Now that the tranny is out I am wondering if I should go ahead and purchase the gear position sensor, tap a hole in the transmission and install it or do what many have done before and just code it out. I mean is there any advantage to having the gear position sensor?

Do you want cruise control?

Yes - I do, but mainly to keep functional everything that was there before the conversion. I would rarely use it.

From my understanding to have cruise control, you either need the gear position sensor or make tweaks in DME. Depends on what you are comfortable with.

I think the conversion sticky has info on how to deal with cruise control.
