in 100's of conversions 2 or 3 maybe broke a fork but its still an easy fix.

In the process of getting my LSD (along with DC stage 3 clutch) and steel shift forks installed into the 02Q for my MK7 Golf, and this thread has been read over many times in preparation to this project. I tend to take my time when doing anything on my cars, and this being the first time I've ever been into a transmission I really took it easy. I could not get the case halves separated, and wound up with a permanent reminder how NOT to get them apart. So, after some thought I came up with a super easy method!

The seal broke almost immediately and then I began going to town on the input shaft bearing with the dead blow to get the halves all the way apart.

Once apart I was very happy with what I found inside. ZERO brass shift forks on any gears, and what looks like updated sliders. In all of my reading about these 02Qs, I've yet to come across any without at least one set of brass forks inside. Here is a side by side of the steel forks I got in case I did have brass ones for the 1-4th gears next to the ones in this particular 02Q.
In my VW service manuals, they reference a "Reinforced" version of this gearbox. This can be my only assumption as to why there are different shift forks here.



Also, at least on this "high-torque" version of Peloquin, there are only ARP bolts..no nuts. The diff had four extra bolts included that are used to pull the ring gear down, then install the remaining bolts with connecting plates.

Awesome thread - I lost 1-2 on the way home last Friday (mk4 golf 130K) seems like the rivets gone luckily I was at a stop and it fell out in neutral so I could limp it home in 3rd.

has anyone tried using M8 countersunk in the Shift fork?

Also whats the difference between this and the 02N boxes? I know some internals are interchangeable and both the 02m and 02N fit in the same VW vehicle platform (seat leaon& Golf?
only asking as I have a FWD 02N sat here although I have an 02N 4motion in the sharan I assume that's just a diff-erence to allow the Haldex coupling to work?

Thinking about picking up a six speed and LSD, so I installed the google chrome extension that fixes photobucket links (for the time being) and made a pdf of the first page with all the images. I uploaded the pdf to the TDI Club image gallery so it won't be lost again- you can find it here: http://pics.tdiclub.com/showphoto.php?photo=126080&title=02m-lsd-install&cat=517

I do have a question for folk around this - I have heard "rumors" that folks have used 02Q transmissions in MK4 applications - and drilled the case for the missing mk4 speed sensor - but I have not seen anyone personally claim they have done this. Can anyone here claim success using an 02Q in a mk4?

I put a set of the steel 02Q forks in a 02M but not sure I like them. They have plastic tips and have heard some complain that they are gone after 70k miles.
Much prefer the modified brass forks.

There are brass replacement tips available. My 02Q oddly had different version of plastic tips along with completely different OE steel forks.

I am recently getting some bad noise coming from either the axles or differential on decel that has been getting more and more consistent (worst in gears 1-4). Does it with clutch in or out so ruled out clutch clatter. It does it only on decel, and doesn't seem to make a difference when shifting weight by yanking on the steering wheel. It's wheel speed dependent, not engine speed. Any thoughts??
