7 speed swap
So far I know the 7 speed tranny bolts up and works with the 55k engine but that's about it. Things will need are:
-7 speed tranny, but from what car and what year?
-TCU
-possibly modify drive shaft?
-differential from the same donor car (can the stock unit but use?)
Is this even worthy of doing? Will the electronic just plug up or do I need the harness from the donor car too? Will the TCU need the magic touch from Jerry? So many question, but that's why I'm here.




its also has a complicated software connected to the ECU, through the Starter,
as well as it has an EGS53, which can’t be tuned or reprogrammed......!!
you can modify your exist gearbox to reach A1000Nm,

or put a gearbox assembly from A900Nm", from (S/SL600/65 Bi-Turbo/Maybach 57S/62S).....

I wouldn't even try it unless you have a confirmed person who can make the software for the tranny! And the MCT can handle 1000+ ft of torque if upgraded properly, swapping the engine is easier than the tranny.
The tcu is built into the conductor plate on the valve body. Also the harness is different so it would need to be modified.
The high hp sc 63 guys all run a built weistec trans.
Edit. You would gain shift speed, assuming its a 63 tune or custom. Buy not sure if it would compliment our power band?

Thankss for your support & compliment....!(_)!
ZAYED,,
Please explain. E500, what's so great about switching ?




i didn’t say anything in negative way,
i don’t know how’s nerves here..?!?!
you should to see your previous post, before giving STRANGELY judge.....??!??
ZAYED..
By the way if it's the 7 spd MCT box then I can definitely see it being a great mod because it's so much faster and much more responsive.




Im always doing a customize things, i know what’s that really means(...),,
i said its not worthy & trouble, cause this mod. needs more $$$$, and more time, with unguaranteed results...!<!>!,
i could be wrong, that’s why we need a specialized person to tell us a "Contrary Correction" about it,,
* sometimes opinions will help to find a solutions....

Although MB just put a 7 spd on the V12s and the new 5.5 TT has alot of low end torque but still has a 7 spd so it could actually be a very good mod.

as i know; MB put 5 speed in all V12s from 2004 till now, and they still use it,,
i didn’t heard about 7 speed in all V12 since 2004.....
ZAYED,,
but who can do this?
Sap out airmatic and install coils?
As we all know..airmatic is a very expensive ticking time bomb



Please let me know thanks
The monster torque of the E55 dose not require a gearing advantage and could end up being a slower car with 7 spd. On the other hand the lower torque of the N/A 63 needs the extra gears (Torque multiplier) to keep engine in its power band.
Neither Auto transmissions 722. 5 & 7 spd. hold a candel to the new MCT 7 speed.
