RS2 Tranmissions - CGR vs CRB

[UrS4boy]

i imagine that the gearbox was broken and somebody swaped it

My "theory" (unsubstantiated) is they were replaced early on under warranty when the CRBs failed (first gear galled during massive clutch drop launches). Just a theory.

Well, that *IS* good news. Whether your car left the factory with a CRB or not, it doesn't matter. It's got one now and that is all you need to know.

Checked the transmission today. According to tag in the trunk it should be CRG gearbox. But i have CRB (61198)

Long time since last post. Did you figure out when the "braking point" was when Audi did put the CRB in the cars instead of the CGR box? According to my tag in the trunk i should have CGR, 1994 car nr 924. Will check my gearbox tomorrow to see what i have mounted.

Think I'll have to lift the car to see what I'm doing. It's pretty corroded under there though. Subframes could do with a clean and repaint but I'm just not set up to do that in London.

Unfortunately mine is too corroded to get photo. Either that or the serial number is out of reach.

I'd be surprised if it's corroded to the point that it's not legible, though it's possible if your car's seen a lot of winters on the road and is free of oil leaks that help to protect the alloy casting. I had to clean a fair amount of crap off (mostly oil) before I could read mine properly.

The pic above should help you locate it, a brass wire brush used with care will help revel it along with Dave's advise re a felt marker and alcohol, white spirit or similar would also do the job.

Transmission code and serial number should be stamped onto the transmission edge at the left side out put flange. See below. Trying gently cleaning that area with solvent and then rubbing a felt marker across the area and then wiping the surface quickly with rubbing alcohol on a paper towel. Might reveal the stampings.

Right, mine has a CRB box numbered 64916, so maybe it had a replacement under warranty.

When I changed the oil I got pretty much bang on 2.3 litres out with the car sat dead level and left over night, so that's what I put back in there which got it to 15 or so mm below the fill hole as per the workshop manual.

Left my camera at work so pic's to follow.

If it's any help I can check mine easily in the morning as the car's sat over my pit, will get a photo while I'm under there.
On an entirely different subject I've started scanning the VW 16V info but it's about 30 odd pages and is taking me forever to get them into a format I can send easily, being a self confessed technotard. I am on the case though.

It will be interesting to see if your transmission is a CGR like the build tag says or a CRB. If it is a CRB, it won't be conclusive as to why. We really need some Audi staff person's help here.

Scanning at 300 dpi should be enough. Sounds like you could bundle them into a few multipage packets and send them in batches OR just leave them as is, either pdfs or jpgs. As long as they are labelled, I can transform them at my end.

I'll take a pic tomorrow night.

I'm surprised that the build is so early, the car wasn't registered until 1996!

Mine is ADU...2687 and it has CGR gearbox.

Any photo of the CGR serial number?

ADU 002687 was probably built in the first week of Sept. 1994. The last RS2 built in September was SZ000577, which fits with my *theory* that the OE transition from CGRs to CRBs was somewhere between SZ 000703 and SZ 000900, sometime around October/November, 1994 (??)
