Wonder if anything like this can be done to our 7 speed slushboxs?

 

so If the vin on my e55 ends in 360740, my car has the A240 part

 

Honestly I have no idea lol. I'm very lost with all of this I got a get of SLR 722 valves coming in. I dont even know if they are what I need. EPCnet and the parts guy at Mercedes told me thats whats up.

Cool thing is if these valves are not what we are looking for I don't have to buy them. However If they are using a Mercedes part I can get it at a discount.

I am searching for Kevlar clutch packs as we speak.. that would be a cool mod

All these 722.6/NAG1 transmission guys hang out over at the SRT-8 and SRT8Cherokee forums forums I got a feeler out their with a guy who seems to know his stuff the company name is Paramount Performance Products.

 

I would bet looking for parts from the newer W212 transmissions would be a good place to start.

 

I guess a good place to start is looking for a transmission that shares your common setup... Does the SL65BS have a similar trans? If it does maybe start there???

 

AFAIK, it has the 5-speed like the other 65's, not the 7-speed in the 63's.

 

Thank you hooleyboy for doing the research for us.

 

I heard about the blue top mod about 2 months ago, What I was told it was from the S600 biturbo. THIS IS NOT FACT. Just what some SRT8 guys were telling me.

 

Jack pot!!

 

you the man! did you source them from MB directly, or Southern Hotrod? i have a friend at a local dealer, if you wouldnt mind typing out the part numbers for me i was just about to service my trans, and this would be a great improvement over my slushbox that i have now!

 

Not so simple, I fond these pic elsewere. Just another piece of the puzzel. Looks to me to be A-240-277-00-98 ???
Good luck.

 

Curious... the stamp on the part does appear to be exactly what you claim, ending in 98. The sticker on the box ends in 89, which matches the P/N that hooleyboy posted earlier for SLR and V12TT cars.

 

Part# 240 277 00 98 was replaced with part# 240 270 00 89 So I'm guessing they are the same thing. EPCnet says they basically are... So if you were to order these parts from MB and gave them 240 277 0098 you would get 240 270 00 89.

Now lets see what cars came with these valves.

EDIT: My car did not come with these valves mine came with 140 277 03 98 and was replaced on EPCnet with 203 270 00 89

EDIT: the blue top 240 270 00 89 are for transmission 722.643 my car has a 722.636 what ever that means.

 

So we need to get 2 of the blue tops to replace 2 of the brown tops we have in our transmission?

 

Just called the local dealer and list price is $212 each.

 

I'm thinking yes. If you give the dealer part number 240 277 00 98 or 240 270 00 89 you should be fine. Retail on these is $217.00 a piece so thats $434.00 a set. I know I can beat that price.

 

I just got off the phone with my dealer too... lol. I can get them for $185.00 a piece. I can wait until my other parts guy gets in to see If he can beat it. I was given a quote of $395.00 a set yesterday and now the we are lower so thats a good thing. I'm down to $370.00 a set

 

getmymercedes.com sells for $147.75 a piece...

 

good find

now who else want to try these out?

 

mine seems to have blue top valve already??

 

keep my posted as I may be in on this buy.

 

That's pretty much all there is to it. As an aside, the plastic protective cover over the solenoids has an open window that exposes the tops and one can see if they are brown or blue. My thought was that it could be for production visual inspection.

The end of the units I put in (blue) versus the end of the units I took out (brown) were definitely different. The blue units had more of a recess to them. This would impact the flow. The TCM probably doesn't recognize a difference in the solenoids themselves (the solenoids may be exactly the same), but the fluid flow through the ends will differ.

 

same thing comes up for mine

 

I don't know how to read the EPC printout but it looks like the valve has been updated 4X; A1402770098> A1402770398> A2032700089> A240270098> A2402700089.
Am I reading this correctly? If that is the case, there is really no way to tell what you have until you open it up. My '04 shifts too soft and slow for me so it's worth a look. Thanks to all for providing this information!
