I am thinking of modifying my trany, any idea on vendor/price/time of installing a close ratio trany, heavy duty racing cluch and a flywheel?

Never heard of anyone modefying the ESS tranny.I too was concerned about how the tranny held up under modsthing ,but i was told that MB makes a real sturdy tranny........with other cars that i owned, i had to do a tranny upgrade any north of 400rw.There is a company in .NJ (Level 10) that is a great place to start your inquiry .But they are expensive as hell.

You do realize these cars are automatic and don't have clutches or flywheels right?

Yeah bro....just a matter of cash. You can do anything with monster cash.

Just sounds like too much work and cash for the outcome.

Let's us know if you find anything.

You will probably need a truck clutch to handle >500ftlb of torque...

Hell, Kobe Bryant had a Lamborgini modified from a stick to automatic. It cost him $100K. Maybe you can get his old manual system and do a swap?? LOL!

Dude, break it before you replace it. That's how you find the weak links.

What mods do you currently have?b/c it seems to me like you are thinking manual tranny even b/f you do your first upgrade..........have you actually purchase the car as yet?

MB uses the same transmission in the 65 models so it can handle 738 LbFT of torque and 604 HP for 100,000 miles, so I would imagine it can handle pretty much anything that you can do to a 55 motor. Even if you use nitrous its only a few seconds here and there so I would leave it alone and spend the money on mods. Maybe if you wanted to increase the converter stall speed, but that would probably cause traction problems.

Both Brabus and MKB currently offer and perform modifications to the E55's 5-speed automatic tranny.

i dont have a very clear idea about the e55 trany, just wanted to know your input. there is an RS6 hatchback MTM modified with a manual heavy duty 6 speed transmission just wondering if the same could be done MB. my car is modified with a K4 whithout the cams. running very impressive. i was just think what shoud be done next.

Any idea what mods do they offer for the tranny?

Maybe something that speeds up the shift. God, I can't stand that delay when shifting into drive after reverse. Thank God that I don't live on a busy street.

My understanding is 'strengthening', and modification of the electronics ala ECU-chip tuning(?) to alter shift speeds, points, and logic. All done to the autotranny -- no aftermarket manual trannies available that I know of.

No tuners that I know of, even the shops that are doing race-tuning and very high power-output tuning, don't like and respect and use the current MBZ 5-speed autobox -- including AMG and HWA....

There is a rumour, and a couple of hints have been dropped by MBZ and AMG execs, that they are about to isue a new rendition (electronics tweaking?) of the 5-speed autotranny box - and like in the next few months, and that they are currently testing the changes(?)....

I'm all for it!
