Just made this job. Easiest way to get seal out is to screw small woodscrew throught seal ja then pull seal out using hammer or crowbar etc. I use sparkplug socket to knock new seal in, be careful and watch that seal go in evenly and be sure that it goes enough deep in, otherwise seal can leak.
It is a major pain to do while on the car.. definitely prop out and if doing the shaft seal as well then obviously it helps to take that apart first. Also ubolting gearbox mount helped. Just use gearbox jack to support, unbolt it and then lower it as much as it will go without your engine crushing anything on the firewall and you'll get a bit better angle to work on it. Still a pain to do...
Does anybody know if it’s possible to replace that rear output flange on the rear of the transmission? I don’t see much online but looks like it should be able to be pulled out
I have a 2004 m3 with SMG and my seal is leaking. One night, I during a spirited drive in the canyons, I noticed it leaking a good amount onto my exhaust which caused smoke. It's very odd because right when I noticed this was happening, the transmission started having issues shifting in the higher rpms. Shifts normal below like 3.5k rpm. Any thoughts?
There's low fluid in your transmission so it can't build pressure to shift well, imo. I would top it off to avoid burning out the trans or fox your leak
@@buildanddrive another person said pretty much the same thing on a forum But someone else said you usually won’t run into problems until you’ve lost like 1/3 of your fluid. My best guess is that I lost a good amount fluid causing the tranny to shift odd. There are no codes/lights on the dash either.
Can you give me a website or a forum where I can find the number of teeth of the different gears for example of a GS6-37-DZ manual transmisson gearbox, mounted on the BMW 320d E90?
Yes it is possible... It is really hard to get the seal out. But maybe you can lower the transmission a little bit. There are some forum posts about it online.

Thanks this is a great idea and makes like way easier.
Yall push the shifter rod in, it goes in way more than this, and your socket will fit fine

I bet it is a huge pain for such a tiny seal. Hope you got yours sorted!
@@buildanddrive yeah thanks. Done and dusted! Hopefully never need to touch it again 😁👍🏻
Il be doing this today. I bought the output shaft seal aswell
Is the trans in the car?
Thank u for this video i did it under my car i used a kitchen knife to take it oit 😅😅 it was a real pain
Great idea with the kitchen knife!
Can you do this from inside the cabin with a manual trans? Take off shift knob and shift boot cover and do it from there?
No, sorry.
@@buildanddrive Thank you

@@buildanddrive thanks for the response!
@@diamondplays8944 It wouldn't hurt to fix the leak and replace the transmission fluid
no link to the part no part number

Is it this one? www.automaticchoice.com/de-de/bmw-gs6-17bg-manual-transmission-parts-catalogue
Is it possible replace this sealing when gearbox is install on the car ?

@@buildanddrive Do you know some forums ? I am from Poland and here I can't find this topic.
