How much power can a 722.6 handle?
How much power can a 722.6 handle?
Standalone controller will not make box handle more power. There are many different versions of 722.6, E300td and most of the engines which make torque under 330nm use box that is rated to 330nm. 270cdi, 320cdi and V8 models use stronger box which is rated to 580nm, some AMG boxes are rated to 900 and 1000nm but they are very rare.

standalone controller can make them stronger, as it can run higher pressures. Some more disc clutches in some of the packs will also add extra power for the box, and AMG solenoinds too.

The clutches are the limiting factor until you reach North of 1000lb/ft of torque. Then if a high stall converter and drag tires are used you will start to break input shafts. If you are not going to exceed 5-600lb/ft of torque then the clutches can handle it. Above that you will start to slip depending on use. Machining the pistons for additional clutches and some different clutch baskets can get you pretty much were you want.
The standalone can increase power handling a lot of any box. THe factory does not use the total available pressure in the valve body which the standalone can take advantage of. Increased shift firmness and holding pressures both.

03-02-2015, 05:50 PM #4As said it depends on the particular transmission. But basically if you are going to run large amounts of torque then start with a 580nm box.

722.6 has two pressure regulating solenoids, one is for modulating pressure and second for shift pressure, I belive they are both used for shifting. Or am I wrong? I mean if accelerating with full throttle without shifts then clutches are held by solenoid regulated pressure or constant line pressure?
The working pressure can be reduced to the point that the supplied pressure to these and the supply pressure to both the solenoids can be lower as well. At this point the modulator solenoid can have an effect on the shift pressure as well. This is important for low pressures in achieving smooth light throttle shifts were the shift solenoid can cause to great of a change in the pressure one way or the other. You can use the modulator pressure to adjust the scale a little. But you have to be careful not to have to low of a shift pressure and to high of modulator. This will cause a bind or kick back into the previous gear.

03-02-2015, 07:46 PM #6It is rather complicated in the way pressures are regulated. But they are both active during a shift. The modulating solenoids main function is to control the working pressure at the working pressure control valve, which all other pressures are derived. The shift pressure solenoid controls the shift pressure valve. This valve dictates the pressure applied to the clutches for a shift. Working pressure is applied to the clutches once the shift is over. The other function of the modulating solenoid is to control the overlap valve during a shift. This is to determine the rate at which the off coming clutch drains.

What car, what engine and what power we are talking about?
I don't know what are the prices in Norway but I think easier and cheaper is to buy another box that is rated to 580nm and change only the bellhousing. But then you need standalone controller because stornger boxes have different gear ratios.

(03-03-2015, 07:57 AM)Joystick It is an 722.6 from my 300tdt w210. Is it possible to change the clutch plates to some stronger ones? Or can i dit in more original plates? I do have some New original ones but i dont know if its space for more? Where can i buy stronger plates?
1st you want to check the input shaft and see if it has a bushing or needle roller bearing in the back end of it where the rear shaft slides in. If it has the bushing just get a newer transmission to start from. You can use your bellhousing and converter on what ever you get.
The factory friction material is very good and that is what I use on all my builds. If you want to add more frictions to a particular clutch pack there is really only so much you can do. There are different thickness steel plates on the double sided friction versions. You can typically get one more friction in by changing to the thinnest steel plates. You can also mill the pistons down for added clearance. Again one more friction.
Now for how the transmission was made. The most frictions by design were in the larger capacity transmissions. There will be 4 in b1, 6 in k1, 6 in k2, 5 in k3, and 4 in b2. I am skipping reverse of course. If you transmission did not come with these combinations then the baskets are different. Different heights. Differeent snap ring groove positions. Different pistons. Etc. The problem with changing the baskets is that most have gear sets on them and they are expensive. I do use the k3 from the 900nm transmission.
Hope this helps.

Sounds amazing!If you have w210 E300td with genuine transmission control then it will not work because 580nm box have different gear ratios and car will go limp mode. With standalone controller it doesn't matter. But yes, it should bolt on, maybe you only have to change the flexidisk flange but it's easy.
edit: is it something east i can do with the New gearbox to make it handle more power?

Bolts only, in youtube there are a lot of videos about how to dismantle 722.6.

Okay, should mange to do that. A friend of mine have been overhauling these 722.6 boxes for 30 years! Is there any list over 722.6 boxes, with info of how much NM they can handle and wich car they come from? Would like to go one stage up from 270 cdi so i know i kan put the pedal to the metall any time :p dont Need a expensive 1200nm box but for example a 7-800nm box? What do you recommend then?

Most large nag transmissions come in v8 and v12 cars and therefore have more clutches but there are small nag transmissions that come with more as well. Of course what country you are in determines how easy it is to find certain versions. Here in the U.S. a v8 transmission is probably the most common.

03-06-2015, 09:14 AM #31It is not that important what the rating is from Mercedes. What matters is the clutch pack layout. If you find a transmission that you are thinking about buying you should look it up in the EPC and see how many clutches are in each clutch pack. Other than that it is really a choice on gear ratios between the small nag and larg nag vs.

03-06-2015, 10:22 AM #33You will need to get a bellhousing for a inline engine. All others are different.
whipplem104
03-06-2015, 11:25 AM #35The earlier transmissions do not have removable bellhousings. And the 722.6 it is part of the porting for the clutches etc. Only 722.6 parts are compatible.
