It was a Getrag transmission in the 320SL right? Does anyone know the model? Like for example, the Supra had the R154, and I think a lot of people used it for custom jobs, anyway, if you could cross reference other cars with the/a similar transmission, things might get easier.

I think the problem with this project is that everyone would like to put a 6 speed in their 500E but, like GerryVZ said in an earlier post, they are all waiting on some one else to sink money into it. Since no company is going to do the R&D on this, it is going to take several folks just getting together, pooling resources [money] and trusting a shop to diving in and do one at a fair profit and then commit the orders.
If anyone in the MidWest wants to get together and start working on a real project plan on this, please let me know. I will be happy to help drive the plan [annoying 15 year Sr. Sys Arch and PM in retirement].

I would be interested to know if the 500E tunnel has the same dimensions as the R129 SL, or if they used a different length shift linkage to allow a different shifter setback position. If you could at least tell me the linkage length you have (seeing as your engine is out of the car), it may indicate something. Also, I am assuming at this stage that they have the same gearbox. Can anybody confirm if that is a correct assumption? Starter motor location is another issue. On my RHD car it is on the right side. Is LHD or 500E different? I note the bellhousing is cast such that it can take the starter on either side, but is undrilled on the unused side. The GM differential is looking like the choice. Apart from choosing your ratios, you can fit a locker, LSD, spool, Hydratrack, or a one-legger......take your pick because they are all available to fit it. It makes the tail shaft a simple GM cut/shut item. As a separate issue that I will create a thread on much later on when I am ready to tackle it (Please don't hijack this thread!!): Are you allowed to fit custom extractors/header pipes to your cars in the US? Once I have gone through the 6-speed hoops, I was going to make myself a nice set of tuned length stainless pipes. If they were legal to use in the US, I would make jigs to replicate them. If not legal in the US, I would just make mine one-offs. Crank |

Crank , I believe the emissions regulations vary somewhat from state to state.
In Virginia you can add the header system but must run catalytic converters and still have all the emissions related items installed and operational until a car is 25 years old ( my 82 911SC is about to get webers and uprated exhaust ). It must also pass an emissions test. I am looking forward to following this thread and getting in on the tranny changeover mod. Alan

Interested in Midwest
Hello,
I posted the below message on the Performance ring... I would indeed be interested in learning more about the conversion. For my situation, all I would need are the parts. I have a great mechanic who has a top notch german car shop who is intrigued enought to donate his time on the weekends to help me out with this. My 95 E420 just hit 190K, looks like it has 30K. Quite a nice car, just want to soup it up at bit. Feel free to contact me at any time to discuss this further. Regards, Aaron aaronjwarren@sbcglobal.net I may be considered certifiable for even thinking of this... Has anyone ever hear of or know of anyone who has converted a W124 V8 over to a manual tranmission? Perhaps a R129 V8 SL? I have a lovely (but high mileage) 95 E420. The engine is amazingly smooth and profoundly powerful. A real sleeper. It is my daily driver, soon to be a secondary toy (Waiting for the R320 CDI). BMW has always offered a manual with their 8s, I just don't find beamers as durable and don't care for the styling. I know there are plenty of trannys that can take the power and the torque (Getrag units, and some ZF manuals), but have never really been able to find any info. Any info or ideas or thoughts would be most appreciated. |

trans option
this may sound like sacrilege, but there was a 6spd manual from a Jeep Wrangler Rubicon on ebay a few weeks ago, clean and cheap and represented as strong.

Hey Guys, I thought I read somewhere that Porsche used a MB tranny in the auto version of the 928. So would it be safe to assume that the bell housing could be the same and possibly the Porsche tranny could mate up to the MB engine?????
Might be something to look into |

There is a fellow in Clearwater, FL who has all the neccesary bits to make a conversion in his 560. 126 280 SE Manual for pedals/lines etc early M117 bell housing off a manual SL His feeling is to go w/ the richmond 6sp which I'm partial to. I hope to get down there to pay a visit and brain storm some time in the not so distant future..Hopefully this time w/o getting taged @ 105 :-/ Jonathan

Tremec T56 Conversion
This is an update to let those interested know that we are keeping the dream alive here!
I'm having a little trouble here in Oz sourcing bits and pieces required to create the conversion whilst doing "real" work, but we're on it. I have the right casting people lined up. I don't want to take my car of the road for an extended period of time unless I really have to. So if anybody has a pedal box, a dud transmission case, and an trashed engine block with a crankshaft they want to sell, I can get most of the hard work done on the bench. Same if anybody has a 124 chassis manual pedal box they can loan or sell to me for replication. Has anybody taken any W124 V8 measurements yet to compare with the SL dimensions? What about the 6cylinder varieties? If we are going to make a kit, it has to fit both 124 & 129 V8 cars to make it worthwhile, but if anything can be done for the 6 pot junkies it would be even better. Does a 6 cylinder share the same gearbox bolt pattern as the V8? Has anybody else gone any further putting their own kit together, or has anybody got any useful facts they can add to help this effort? Crank PS:As a separate issue for after the gearbox conversion, I am keeping my eyes out for a V8 intake manifold (if anybody has one lying about!). Last edited by Crank; 10-13-2006 at 10:22 PM. |

Tremec T56 Conversion (Reply)
Hello,
Regarding bolt patterns on the W124 6s and 8s. I did a bit of digging and found that they are indeed the same. The cases are actually pretty much dimensionally identical, at least the bits that bolt to the block and the frame. I have a 87 300D and a 95 E420. I measured from some key chassis components that are common on both cars, to the bolts, and the numbers matched. Granted, I didn't dismount the tranny's but I'm willing to bet that they share common dimensions. Looking at pics of trannys on the internet, I can't find any differences in the castings. In a previous post someone asked about the trans tunnel dims being wider on the V6, and the V8 having a narrower footwell, making the addition of a clutch pedal tricky. I measured every possible interior part of the foorwells of both my cars, the V8 is actually 11mm wider at the firewall than the V8. Can't figure that one out! Might be more insulation on the diesel? Please, keep me posted on any progress, I am planning on getting the conversion done by someone who A) has the parts and B) knows that cars well enough to do it. Feel free to contact me off thread at any time. Sincerest regards, Aaron aaronjwarren@sbcglobal.net

Tremec T56 Conversion
Aaron,
That's great if they are in fact the same dimensionally. A difference in the castings that I have seen is the V8 gearbox has provision for LH & RH starter motor, but the 6 pot gearboxes I have seen do not. As you have implied, it is difficult to see the interface properly in a vehicle, so we'll not know for sure until somebody has one on the bench where the bolt centres and other influencing points can be measured with certainty. We also need to know about differences in the crank flange dimensions. Crank PS: Still looking for parts. |

I'll be getting a 16V trans. here pretty soon, if you want me to post some pics of the bellhouse, etc.
