3.06 Gear install plus TCU is a no go for me

Looks like my issue has been fixed. After doing some digging I found out that the W209 CLK55 has the same TCU as us, along with the same tranny 722.6. Best part about it is they come with a 3.06 gear from the factory, the exact same gear I put in my rear end.
I bought a used TCU out of the above mentioned model, threw it in, and hoped for the best. I have driven the car for a full day now, and got it threw the gears and up to 100mph, and have not got any codes or limp mode yet.
I am still having a custom TCU done in the mean time by Marcin to my specs on shifting points etc. One bonus is that I can turn off traction control and do standing burnouts with this tcu. I could never do that in the past with my 06 TCU.

Can't wait to see you back at the track. Who told you about the clk tcu? I hope it works out.

Awesome! So how do you turn off the traction control ? Is it the same button that just has a different effect using that TCU?

What a tease Craig, 2 years ago my wife had to go and have our 2nd daughter the weekend that Timmayfest is always held, making it impossible to go. It would be great to line up together I think my only shot would be to hope you don't hook lol!!! Well good luck!!! I'll be watching for updates and hoping that you do get that beast out of the hole with a crazy 60ft. ....with the gears in working order who knows what can happen.....

This is a good discovery. I foresee junkyards getting raided for these TCUs now.

Ahmad and I were talking about the issue and he said you know that the c55 came from the factory with these rear gears. So I started a thread in the m113 sub forums and those owners verified that the clk w209 coupes had the 3.06 rear gear, 722.6 tranny and egs52 tcu.
$180 for the tcu off eBay
$100 srt8 3.06
Parts cost!
The car feels WAY lighter on its feet and just seems to be at the right rpm in all the gears cruising on surface streets. You can definitely notice the higher rpm over the stock 2.65 gears. It pulls incredibly hard when you go full tilt and anyone going to timmayfest is welcome to go for a spin.
The tranny also seems to gear down a lot more with this tcu and 3.06 gears. It also holds gears longer in sport mode at part throttle. Definitely a good upgrade for the money invested.

.......sorry I didn't know there was a question about this. I changed my W210 E55 from factory 2.82 to 3.07 a while back by using the tcu from a C43. I still question whether it's a wise move because the car just spins tires in first gear. I now drive it in winter mode which is second gear. But as far as how to do it, using the tcu from another car that has the 722 transmission and the gear ratio you want is the way to go. I have had no issues with mine for 9 years now. As everyone knows, I am not a big fan of the tuning portion of the work done by Mercedes shops. Despite these cars being out for a long time now, the tuning side of the performance work is still unfortunately hit or miss.

what year of W210 E55 you have, do you have EGS51 or 52,
as i know; the C43 got EGS51, which is hard to deal with,,
did your E55 ECU accept that swapping with different RPM ratio with-out authorized from Star/Das......??

......mine is a 2000 E55 which matched the EGS from the C43. Have had no issue with rpm matching.

WaaaaaW, its very good info., that means, we can swaps whatever the diff. ratio from any 55s models,
cause N/A 55s sharing the same TCU data/file & adaptation,,
we can say that explain; why (C55/CLK55/SLK55) with "3.06" works great with an E55K.....

05 crossfire w/SL55 drivetrain installed by Rudy Compart Intake/Needswings best et-10.76 @ 129
got my transmission rebuilt,the tcu is from Speedriven, the 3.27 ratio now works like it was made at the factory,, shifts when i tell it to ,I made 5 runs at pbir last week 11.044,,11.049,,11.054,, 11.054 and 11.160 all at 126 to 127 mph, oh yea, the Iat were over 110 on every run,, had no ice,
Craig, glad you got yours up and running the way you wanted,
Now that we know that Speedriven can do it and do it right. ,, maybe some 3.91 gears. jim

Once I can see where I am at with these gears in the 1/4 since I am moving my shift points back down to stay within peak power for each gear, I have a feeling I will be shifting into 4th right before I go through the traps. If that is the case, I will definitely be going with more gear. Just trial and error as you know
She is definitely a happy camper right now, thanks for your help through this upgrade Jim

Yes, I just installed a 3000 stall converter at the same time and it pushed my peak tq from 2500rpms-2800rpms on the stock converter, to around 2800rpms-3400rpms on the new stall.
If I flash the converter on the dyno, it will tq spike around 2800rpms with the new stall way up there.
Dont forget too that I am running 28" slicks now, not the standard hoosier 255-50-16 which are 26" tall. I need more gear to get the taller tires turning quickly but not to much that they start to spin them if that makes sense.

Jerry from eurocharged told me that on S class you can change gear ratio through star and would not need custom TCU. Would anyone be able to confirm that for me? Because the mechanic at my dealership had no idea what I was talking about.
thanks

chawkins2001: Did you have to make any changes whatsoever through Star to be able to make this work? I'm trying to figure out whether if I buy a EGS52 TCU + gears off of Ebay, and just simply install both, if this will work. 
Thanks!
Edit #3: After looking at your other threads it looks like both the W203 C55 AMG and the W209 CLK have the 3.06 gears and compatible TCU? By any chance would you be able to provide the model, exact part number. and year that the TCU came off of?

Attempting to do even more sleuthing here, and I also have a hypothesis...
TCUs from 03-04 on E55, C55, and CLK55 all likely allow for burnouts, whereas TCUs from later cars (05-06) probably don't on the whole, with exceptions found by a few people. I'm also going to take a stab at this and guess that for some people in the later cars that CAN do burnouts, their TCUs have been replaced at some point, possibly due to the wicking issue mentioned where TCUs have gone bad, and maybe have older revision TCUs. Nothing to back this up, but it's a guess.
Anyway - here's my next step... I'm trying to figure out part numbers of TCUs that allow for burnouts, and those that don't. It looks like there's 3 different TCU part numbers for the CLK55, and only 2 for the C55. See my image below:
Can you guys help me complete the knowledge gap here so we can figure out what it will take to reliably put TCUs in our E55s compatible with both 3.06 gearing AND burnouts? I will update this image as we learn more. Thanks!
Sources: ChiCho55AMG swapped a '06 C55 TCU, part #0345451632, into his '04 CLK55. Transmission behavior now matches hitting-limiter-in-gear behavior observed by E55 owners that can't do burnouts...

Can you guys chime in with the model of your TCU if/when you know it? I think we could uncover some potentially very interesting info here, and also discover if for guys who want to keep their stock read end, whether switching to a first gen stock E55 controller will allow for burnouts...
Also interesting tidbit, was cruising the Chrysler forums and found that they use TCUs 1 part number off from ours, called EGS53 (as upposed to our EGS52): http://www.ebay.com/itm/Mopar-OEM-TCM-EGS53-P05150729AE-SRT8-RT-Charger-Magnum-300c-/190867085506?pt=Motors_Car_Truck_Parts_Accessories&hash=item2c709098c2&vxp=mtr

As i know; the "EGS51 & EGS53" can't be programed,, any "EGS52" from "C55/CLK55/SLK55", will works with 3.06 end,
"034 545 14 32" or "034 545 16 32"

Sorry, I just saw this. Yes and no, buy the 3.06 gears and get EGS from a CLK55, C55 etc. I did not attempt to do the gear cal through STAR, so I cant answer that for you.
What I will do is PM what you need to get done outside of running a C55, CLK55 etc egs to compensate for the swap.
