Default Comprehensive SMG to 6MT Conversion Thread

I am getting ready to reinstall the trans and Iím stuck....

I took things apart 2 weeks ago, and was unexpectedly pulled away from the project. I feel like a idiot for asking this as I know that I should have taken pictures b/f I walked away from the project. But none the less, Iím stuck and naturally in a time crunch, b/c I need the car back together by tomorrow. 🤦

Im hoping someone can guide me as to which port/hole the locking pin, compression spring, and thrust pin go into. Also, is the orientation of the locking pin relevant? In my mind, I felt like they were in the port/ hole the gear position sensor screws into. However, I referred to this exploding diagram from real-OEM, to be certain where stuff goes, and it appears there 3 ports/holes for things to go into..



However on the actual transmission, I only see 2 holes/ports. Am I misinterpreting the diagram on real-OEM, or am I missing something on my trans?


Not sure if itís relevant, but the purpose of pulling the trans wasnít for an SMG swap; my car was always a 3 pedal car. But, my 3 gear synchroís weíre shot, and I was able to pick up a 70k mileage SMG trans for a reasonable price. So I felt the best option was swap my bellhousing onto the SMG trans and hear I am...

Any help is greatly appreciated.

Parts 8,9,10 on the diagram go into the hole you tapped for the gear ID sensor in the "new" smg tranny. The lock pin (8) has to have the roller in horizontal position. The pin (10) has to have the "pin" end face outward (it is what will press against the ball on the gear Id sensor (look at the gear ID sensor (11), it will make sense), then you put the spring over it. Then you screw on the gear ID sensor (11) onto it.

Your top left red arrow seems to be "done" and is the gear id sensor. Bottom left red arrow is for parts 14,15,16, which you don't have to touch.

Default Comprehensive SMG to 6MT Conversion Thread

Just to clarify when you say the roller on part #8, needs to be horizontal, do you mean the actual wheel/roller would be spinning (rotating) towards the front or the aft of the car/transmission. And the wheel/roller should not be able to rotate/ spin towards the bottom to top of the trans.

I assume part #8 should have some pressure, and needs to be lightly tapped into position.

Sorry for these newbe questions, and I really appreciate the help.

Yes on your interpretation of how the roller should be positioned.

You don't really need to tap it in, just push with your finger. Get the tranny into neutral. Push the roller pin in. That will be the farthest the roller will travel into the tranny, because there is a groove on one of the shift arms that makes some space for the roller to sit in. Then shift the tranny into any gear, you should feel the roller push outward toward your finger.

To understand this a bit better, look inside the hole you would be putting the roller into and move the shifter around through the gears, you will see the groove on the inside shift fork move.

just a comment, but definitely like the use of the harbor freight dolly to hold the tranny - definitely the way to go!

Plan on doing the SMG to manual swap in the coming weeks and will be using this as well.

I have the SMG bellhousing and my old trans. If anyone local to the NY,NJ, CT area wants it, I am open to offers. Possibly it would be easier for someone to be able to convert this SMG bellhousing prior to pulling there trans.

Have yet to find any info on here regarding the offset location for part 1 to remove the GPS from the DME, so I'm assuming people with 04+ cars are skipping this step when they realize the offset is incorrect for all models.

If anyone knows the correct offset, program version in question is 2001, I'd greatly appreciate it for future reference for all.

Any idea??

I answer myself. I changed in 4028 to 00. I did not work in 02 or in 01.
Now the cruise control works but without a clutch sensor, this means that when I put the clutch on while the cruise control is being revolutionized +-1500rpm and it is deactivated. It is not instantaneous.
when I brake, it is instantly disconnected.
so if you do not want to spend 60 euros on the clutch sensor as I did I can do this. Someone wants an OEM clutch sensor???
