Unhappy Manual transmission - What are these two bolts??

I went to change the fluid on my 2013 and removed the wrong bolts. I am now struggling to put them back in, as they reeeally want to go askew and cross-thread.

They weren't particularly hard to loosen, though they were on the firm side while unscrewing them all the way out. Anyone know what they're for, or more importantly, how I can get them back in without stripping them? They are absent on the parts fiche PDF that I downloaded from Porsche...

eek, i think those are some sort of guide pins that keep either the shift forks or rods in the correct place. So to get everything to line up, you may have to move the shifter around.

Do some research here though because I think theres the possibility of a spring or spacer that might fall into the gearbox case when these are removed.

That is precisely what I'm afraid of, though I kinda looked in the holes and didn't see any mechanism. There are two matching suckers on the right side of transmission.

It is hard to research these things, 'cause they're so rare...and I keep reading that the official Porsche docs aren't wholly accurate!

that might give you some insights, but if you took them out with the tranny in neutral, i'm not sure you can shift it into a gear to reinstall.

sorry man, thats a bummer

Yeah, those definitely look like fulcrum pins. It's in first gear, so I'm gonna sniff around and see what I can find. Worst case, I'll convince myself that the clutch was about to go anyway...

I remember thinking "That doesn't seem right—I better double check" and then I got distracted and comfortable about how easy this would be with these two easily-accessible bolts!

You underneath the car with a long allen, same diameter as the bolt pin. . Someone else in the driver's seat. Mark the allen the same length as the bolt. You try to get the allen into the the hole the same depth as the bolt would be. You may be able to align the stuff inside without the person in the driver's seat having to do anything.

If not , then decide if you want the person in the car to move anything, gently push the clutch, gently shake the stick. Don't do anyting to drastic.

someone did this on a GT car and it was a transmisson dropand disassemble fix. Hope yours is not this.

Good luck and keep us informed.

I appreciate the tips! By the look of it, I think it's more or less in position, but not perfectly. When I insert the bolt, it'll go in all the way to the threads, but at a slight angle such that the threads won't engage properly. I just need to pry it up half a millimeter...

I found a bit more info by looking for Touareg stuff...I believe this is the "08D" transmission made by...I dunno, VW? Can't find any Getrag/Aisin marks or info. Based on the (rather nice) diagrams, I think I removed the 1st/2nd and 3rd/4th selector fork pins:

I'm scared to touch anything, lest they drop into the gearbox...

Fun fact: Even VW puts quotes around the "lifetime" fluid description...

You might be able to pry through one hole and insert bolt in other .

Man, I feel for you on this one... Hoe you're able to fix this on your own.

Last person posting on here about removing the wrong bolts decided the dealership was close enough to drive to, lol... Hopefully you don't go that route!

Disaster averted.

I inserted each bolt to the threads, and then just kind of...used both hands to leverage the bolt straight (pivoting where the threads meet) and caaarefully twisted it in. I just eyeballed it to make sure it was straight...When it felt like it was threaded, but becoming difficult, I double-checked visually that the bolt was square to the face and gently wrenched it in and then torqued it to 22ftlb. I couldn't find a good source for the torque, but 22 seemed reasonable. The bolts might be aluminum, and they were not difficult to crack the first time (unfortunately?).

Shifting is slick as snot through all gears. I am much relieved.
