Does anyone have a local tranny shop that rebuilds the Getrag 5-speed. I have a couple that I would like gone through.
Wow! And to think I was considering getting one. Thanks for the info.You're going to have a REALLY hard time finding anyone with the parts to repair a Getrag anywhere in the world even. It's getting to be a risky bet to pay the enormous money for them and then at some point, either right away or down the road, get them repaired. They haven't made new parts for them in decades and the number of available key replacement gears and widgets worldwide would fit in a shoe box. Charles Goin has been leading the charge to get them and have them rebuilt. I think he has one guy in Europe and another out in California and that's it. I know of at least 10 Opelers whose Getrags broke and they can't get them fixed. Some have had to put their 4sps back in.
As a counterpoint, many of us are huge fans of Getrag 240 5-speeds. There really isn't a "plug-n-play" (almost) alternative, and they are terrific transmissions. Are parts expensive and a bit scarce? Perhaps, but they are very robust transmissions, and there are a number of repair options. Which may never be needed...Wow! And to think I was considering getting one. Thanks for the info.
Hi All- keep this in mind- the BMW 318iS is a similar but different car with a different transmission and engine... the iS does not use the getrag 240, and it is a 1.8l DOHC motor instead of the 1.8l SOHC motor that was last used (in the US) in 1984 and 1985... ErnieTo give more comparison between the BMW and Opel Getrag 240s...
BMW Gear Ratios
The 318i's had 1st - 3.72, 2nd - 2.02, 3rd - 1.32, 4th - 1.0, 5th - 0.81, and reverse - 3.45. The 318iS had 1st - 3.72, 2nd - 2.02, 3rd - 1.61, 4th - 1.0, 5th - 0.80, and reverse - 3.71.

Opel Gear Ratios
1st - 3.717, 2nd - 2.019, 3rd - 1.316, 4th - 1.0, 5th - 0.804, and reverse - 3.445 are the exact values but this looks like the Opel gear ratios are the same as the 318i, and I'm thinking the 318i and 318iS actually have the same overdrive.
This just reinforces my belief that the internals would be interchangeable for the most part. BMW did have Getrag do some revisions to the 240, which from all the parts lists I've seen seems to mostly be the synchros and front bearing. I know some of the synchros are the same as Opel but at some point during the 318i's production, BMW had the synchros and front bearing improved. I haven't looked into it enough to identify when that change happened. The BMW Getrag 240 is in the same boat we are, a lot of the parts are no longer made. But you can find a lot of NOS parts still floating around in warehouses for BMW if you look hard enough.
I have a feeling that sometime soon, someone will have to buy a BMW Getrag 240 for the internals to try and rebuild their Opel Getrag 240. That's when we'll learn just how much is identical between them. You can find them on eBay for a few hundred bucks.
According to online BMW parts databases, the 1989 - 1991 318iS did use the Getrag 240. It was the E36 318iS from 1992 to 1996 that used the Getrag 225. Both versions used the M42 engine. I would not have included the info from the 318iS if I wasn't positive that the Getrag 240 showed up in that car. I'll trust parts databases that go by the month of production from BMW over pretty much anyone else. So unless you can prove the bellow website is wrong Ernie, the E30 318iS did use a Getrag 240.Hi All- keep this in mind- the BMW 318iS is a similar but different car with a different transmission and engine... the iS does not use the getrag 240, and it is a 1.8l DOHC motor instead of the 1.8l SOHC motor that was last used (in the US) in 1984 and 1985...

Not quite true. There's some special tools that help getting the shafts properly aligned for reassembly. Some have done it without the tools but a shop will spend a lot of time if they don't have the tools and unless you're willing to pay them by the hour rather than by the job, they probably won't want to do it. After calling several shops that specialized in manual trans none wanted anything to do with it. I found one in metro Atlanta and their response was "yeah, we should be able to do that" and I provided the parts. A couple months later I get it back and not feeling quite right. Sent it to CA to Gil's guy. Found a couple missing parts and a couple springs in the wrong places. Sure, go ahead and take it to any tranny shop.It's a stick shift tranny, any tranny shop can rebuild those. It's getting the parts that is becoming increasingly difficult.
The difficult part is making sure you buy the right synchros and a rebuild will need some. Pretty much everything else can be sourced with a little searching but it's easy to think you got the correct synchros and then find out they are different. There is a BMW synchro that is identical, but I'm not sure which one. I think Charles knows the right part number. I was fortunate enough to source a total of 7 Opel NOS synchros but it took a couple years.It's a stick shift tranny, any tranny shop can rebuild those.
