AMG bluetop solenoid part number - m1tch - 08-04-2015
Hi all,
I will be looking to upgrade the shift solinoids to the blue top AMG units in my 722.6 transmission, does anyone have the part numbers for them - I am guessing that they are Bosch units? My thought is that it will be most cost effective to simply get the Bosch part rather than the ones with Mercedes stamped on them that are usually more!

ECS tuning has the best deal on these (at least here in the US)

Are there any alternative parts which could be used instead or is there a way to upgrade the stock solenoids?
RE: AMG bluetop solenoid part number - Duncansport - 08-05-2015
Not that I know of, obviously a stand alone controller would help.

Thanks for that, I will start saving - or indeed just see if I can buy a complete 722.6 AMG box and take the valve body out of it.

The only AMG 722.6 that uses the blue tops is the SLR.

Thanks for pointing that out - will probably just buy the solenoids separately although am tempted to try out the valvebody upgrade kit which increases the line pressures but retains the stock solenoids.

The v12 tt transmissions have the blue tops in as do the later 55k cars.
What are you trying to achieve with what car and how much power. Maybe I can help point you in the right direction.

I have a W210 E300 OM606.962 engine with the 722.6 box, I am going to be retaining the stock ECU (with a remap) as I am keeping the stock EDC fuel pump (but with 8mm elements), I am looking to beef up the stock gearbox slightly by upgrading the valve body to increase the line pressures. The car is a project car and will be used for drag racing at Santapod, will be looking to run around 3-400bhp, I have a GT3582 which arrived today. I am happy with keeping the auto transmission as it holds the boost between shifts etc and I can also use the standalone 722.6 controller in the future. Considering the V12 engined cars are running the 722.6 box rather than the 722.9 boxes I figured it would be due to being able to hold the extra torque.

For those power levels you can just have the box beefed up for the extra power. I would cross reference the clutch baskets in your box in epc to see what it has in comparison to a v8 transmission from say an E500 or S500. Add the extra clutches were required. Increasing the main working pressure is not really necessary. What you need to increase is the shift pressure. Blue tops would be a good way to get this done. They net between 25-50psi for shift and working pressure. This is a pretty big gain in % of the total pressures in a stock valve body.
If you are going to go with a standalone tcu you will not need valve body mods as you can tune the pressures. But you will not have tq management during gear changes either.

I will check the clutch packs, I believe that the AMG versions have an extra plate vs the non AMG versions - the standalone TCU might actually be the cheaper option. I also saw you can get an upgrade kit from Transgo which increases the shift pressure much like the blue tops.
I won't be putting extra power through the box for a fair while anyway so will go through some different options.
RE: AMG bluetop solenoid part number - Petar - 08-07-2015
An idea i had for torque management with a standalone controller and EDC pump is a transistor mounted in parralel to the MAP sensor. When the standalone TCU outputs a signal for upshift it pulls down the MAP sensor output and the ECU thinks manifold pressure is reduced and cuts fuel.
RE: AMG bluetop solenoid part number - whipplem104 - 08-07-2015
That is not a bad idea but you would have to try it to see if it would work. Also not set a fault code.
