Hi I am in need of some help in converting my car from an automatic transmission into a manual transmission.

The reason behind this is my transmission has recently decided to blow leaving the car parked in my garage without any use. I have always wanted to have a manual W215 and saw the opportunity to do so. I have found several threads showing m113's having manual swapped transmissions on c's, clk's, e's, etc... but not one of them was a cl. The problem is being that it has not been done on a w215 before it is going to be a lot harder. I don't have much experience doing diy work so am going to need a lot of help in doing so. I do have a list of all the parts needed provided by a fellow member of the forum @dzmitry, but there are a lot different part numbers for the same part and don't know which would suit the w215 best. I am also afraid the programming part would be hard and could possibly trash the entire project since I have no prior experience using any of the software.

I see a disaster in the making. Have the transmission rebuilt or get rid of the car and move on.

I am sorry but I have to disagree with you sir. This car has been in the family since it rolled of the showroom floor so getting rid of it is not a choice. I can rebuild the transmission easily but have always wanted a manual w215 and saw this opportunity, being that the transmission is blown I can fulfill that dream. Thank You for your suggestion sir I really appreciate it!

Is there no manual Mercedes transmission from another Benz model that would be available , and could be installed in your car without major modifications ? Or have you decided that the original transmission number shown on the production plate has to be preserved ???

Awesome

If you think you can do the mechanical side if the project, I'd still go for it. The only thing is what transmission do you plan on using, the only transmission that is a direct match is one out of a Chrysler crossfire but I don't believe it can handle the power a M113k makes. I know of a company that makes an adaptor for the bell housing to a BMW transmission but I've still never seen it done on the CL platform. Programing wise I think all you have to do is program it to be constantly in neutral and get rid of the rev limiter. But either way do as much research as you can, good luck.

I'm sure @BenzNinja can help you with the programming part

A manual 55 would be really interesting, but I feel it’s better suited for an auto as the car is so heavy. That said, go for it so we all know.

What is wrong with you?

I don't think he ever finished this?

I think he gave up. E55GreaseMonkey's word might be prophetic. Maybe he's secretly Tavarish lol

I've done it successfully. My 55k has been manual swapped going on 2 years now. There was a ton of trial and error involved, and it got expensive... quickly. Your parts list is good, but I recommend using kangaroo Clutch's max power offering for these cars if you're gonna stick with the NSG370 transmission (crossfire). I did CD00A from Nissan and some of the XF Motorsports adapter kit... but I'm at about 700 to the wheels and needed all the transmission strength I could get. For the electronics side of things, Mercedes Swap Shop has got you covered. EZ. It's a TCU and then I recommend getting his ECU tune as well, as he uses manual pedal maps and you get boost at all RPMs, not just the higher ones. If you're around stock power levels/lightly modified, I think you're fine with the NSG370, but it is unproven at high power levels to my knowledge... whereas you have a billion clutch options for the CD009- including twin disk, etc.
