tip-tronic in pre-2000 models
If I don't have to spend oodles of money on a whole new valve body, I might actually be the guinea pig and try out this mod
ALL C43 transmissions have the #140 270 01/02/03/04/06 06 valve body assemblies including the 2000 C43 w/tip.
1) replace the brown top solenoids for the blue top solenoids #240 270 00 89 ($160.80 each)
2) replace shift assembly from #129 260 45/46 98 to #202 267 08 24 ($426.72)
3) replacing TCU EGS51 from # "021 545 84/86/87/88 32" to EGS52 #025 545 21 32" or "027 545 10/12 32" or "030 545 20/23 32 ($150.00)
4) Guage cluster with gear display
So that should be a final list of parts for the tip conversion, plus wiring from the gear selector to the cluster to show the gear display??
Can anyone confirm the need for the blue tops? This is an upgrade in W210, W203 and W211 cars, so why would tip not work in our cars without it?

Also I called my benz parts dept. and they said that valve body assembly #140 270 06 06 is what is already in our trans, so I don't see why we would need to change that.
"04 06" & "06 06" & "00 06", (the linkage arm that holds to the bottom Electro. piece & the middle filter behind the speed sensor),, you can put the blue
solenoids only in your exsist valve body,, but in this case you well force a hard firm shifts specially in the 1-2, cause the switch in the +/- gives a different
signal to the valve body,, that’s why MB NOT sold that switch separately..........

Once I'm back in NC after school is done I will hopefully take it to my shop who can drop the pan on the tranny and get my p/n from the valve body.
For now though:
I have ordered a 2000 E55 TCU and will soon be ordering the new shifter assembly.
Hopefully, I'm going to install just the assembly and see what happens. Then I will add the TCU, Blue-top solenoids and/or updated valve body as needed, and then hopefully we will all have a clear idea of EXACTLY what is needed to do this upgrade and a cost
From there it is smooth sailing on the way to being the only W202 with paddle shifters

I do not think it will work with just the shifter assembly as your TCU will not understand the signal it is receiving from the shifter. Keep in mind "P", "N", "R", and "D" are the only gears that are shifted mechanically, "4", "3", "2", and "1" are all electronic. If it did work you wouldn't be able to shift manually through the gears. Everything I had listed above will need to be swapped to have a legitimate swap to the NAG 1 shifter (and in turn paddle shifters)

That's very good, you definitely got the update one,, as i said before you don’t have to replaced the TCU, first thing put the blue solenoids without
replace the TCU and see, if it works without any issue, that means everything OK,, but if isn’t, then you have to reprogramming it, to match a new
signals,, don’t forget something important; since you well keep your 3.07 diff., it means you have to reprogram your exist TCU, but if you well put an E55
2.82 diff., you well have to switch the TCU to the newer one, with fully RESET.........

Zayed: I don't understand how changing the solenoids affects the abilities of the transmission. I thought all the blue tops do is increase the pressure over the brown ones?
Everyone else: If anyone happens to know the part number of the harness that goes from the shifter assembly to the instrument cluster to show what gear you're in, I'm in need.




important to know the TCU has directly related to the diff. ratio in your car,, sure, the blue solenoids gives more fluid pressure = more strong & fast
shifting, and also helps to prevent slippy between shifts, thats why MB replaced all browns to blues, after 2003,, there’r "2" #s:
"202 440 69 09 or 202 440 70 09", depend of MB production for these harness #s.........

with 2.82 diff. ratio,, "{this note only incase if you go with 2.82}"....

If the 55's are using the 2.82 diff wouldn't that decrease their off the line performance???




its very good point,,: when i swapped my Engine to 55s, i kept the original diff. which is 3.07,, i raced my friend "3" times,(who has a true C55 with 2.82
diff., i felt his weak point from the 2.82 side,, i think maybe AMG put 2.82 for hit the limiter final speed to reach more than 290km,..!!, i personally like
3.07 or smaller like 3.27........

I have the shifter and the display on the cluster.
Not sure if the other shifter will work with the tiptronic trans or if there is a specific module in the trans.
signal to the valve body,, that’s why MB NOT sold that switch separately..........

I think I mis-spoke earlier though. The CLK55 has the same rear end as the E55, a 2.82 I think. Our C43s use a 3.02. You need to find a car, with EGS52, that has a 3.02 from the factory. Or you can upgrade the diff to one from a Clk55 or E55, but that is a headache all in its own right. The other option is getting an EGS52 and then hoping to use STAR to change the diff size in the computer.
Also I don't believe the wiring to the trans is any different, and I'm not sure about the driveshaft.
Also keep in mind, if you go through with this upgrade to Tiptronic, you are being the guinea pig. Members on here have talked about this for a while, but no one has gone through with it yet.
Steering wheel's the same. No paddle shifters or anything. That was going to be my next step after doing the Tip
I thought someone has done it already what would be worst case scenario?
You will need extra wiring to show the gears on the cluster. Unfortunately I don't know exactly what's needed, but it shouldn't be too hard to wire up.
Worst case scenario would be you buy a bunch of stuff and it doesn't work. In which case you should be able to leave the e55 trans (assuming it fits the driveshaft fine) and put back in the orig. c43 TCU and shifter, and it should work just as it does now.
