Hey guys, so I'm not sure what's happening to my E55 but I'm getting concerned. Its an 06 E55 with 125k miles. Ok so I have a few issues happening and I'm hoping someone can tell me what to do or what' wrong. So first off, the other day I was driving normally home from work when I was about to pass someone driving slow. I gave it some throttle and the car jerked a few times...it felt like it was starting to jump as if it was in 1st gear @ like 5000rpms and I was tapping the gas. So I let off and the car went back to normal. When I got on a clear straight road, I put the car in sport, 1st gear and turned off TC...at first I floored it and of course the car through me back in the seat and burned out like crazy which is normal lol. But then I wanted to take it slow and listen to the car...So I came to a stop in 1st and gave it throttle slowly and when the car got to about 3500-4000 rpms the car started to jerk again?

Now for issue #2, I raced an SS Camaro the other night that was asking for it and from a dig with TC on, we both floored it and I took him which was great lol. Got the car up to about 120 and he never stood a chance. BUT at the next light we both started at dig and when the ligjt turned green we both punched it and for some reason (even though i clearly hesrd my car reved up like crazy) I wasn't going anywhere. The rpms were raved, the car was moving but it felt like the SC wasn' there! My TC light wasn't blinking or nothing and the car was just blah! The camaro of course took off. What in the hell is happening to my car? I've read so much on things from MAP sensors, TPS going out, SC clutch, IC pump, etc etc. I need help.

When's the last time your transmission was serviced (fluid and filter)?

SilverDameon55

Not sure to be honest. My mechanic told me that the MB tranny fluid is a "lifetime" fluid...I requested to change it but he told me I shouldn't

rapidoxidation

"Lifetime fluid". When your transmission stops working, the fluid's life is over. You could do the same with engine oil, with predictable results.
Lots of reasons to be proactive on this by changing the fluid every 50K or so, some would say sooner. Ask your mechanic why he says you shouldn't. I'm curious to hear his answer.

Find a new mechanic. Seriously.

Sounds similar to when my transmission went out. Get the codes read with star.

Mathi

There is nothing like 'lifetime' fluid. I can't believe a tech told you that. I would go to another shop for sure if they told me this.

Anyway, sounds like something is wrong with your transmission. Get the codes and see what happens.

Sounds like your intercooler pump is shot. Get an ELM327 obd2 reader from ebay and the torque app. Check what your air intake air temps are. Or just replace the pump its cheap snd easy to do.

Here in NZ the dealership services the transmission every 37,000 miles as per their schedule for 2006 cls55

How easy is it to do the tranny fluid change your self

SilverDameon55

I'm going to change it this weekend for sure. Do I need to drop the pan and just do everything or should I just do the drain plug. I found a diy on it

Trans fluid, and only use MB fluid.

while you're in there you could do conductor plate and 13 pin connector, but its a little more involved. first i would hookup star and see what stored faults you're getting from the trans. If you need an ELM 327 we have them. and if star is giving you speed sensor faults the conductor plates you can find here > Conductor Plate

We can get you a conductor plate for $140

Try flushing the fluid and changing the filter. Was the transmission in sport mode? Sport mode locks the torque converter. You can check the clutch plate wear in STAR if you have a system. Check the fluid level as well, you're going to need a tranny dipstick to do anything to it, so I'd start there. My car popped out of gear a couple times because of incorrect fluid levels, so that should be the first thing to check.

I just had my transmission flushed at Mercedes dealer at 57K miles, I was able to see the fluid coming out versus the new stuff. It was VERY noticeably dirty, and the dealer said it was a very good thing I had done it. This was on an E63 that has been absolutely babied it's whole life (57K miles in 10 years).

tw2

I strongly suggest getting codes read before doing anything. No point replacing a good conductor plate unless you can't find a single other thing wrong. I did mine hoping it was that... it wasn't, my clutch packs were worn and needed replacing which STAR showed. The electrical bush is certainly worth replacing regardless as it is very cheap and often fails.

SilverDameon55

Ok so not to sound dumb....How do I get STAR? I understand it's a program but how and/or where do I get it? I' going to the dealer Saturday morning for a balanace and alignment...should I have them check the codes and should I have them do the tranny fluid change since it' quite clear I need a new mechanic?

tw2

Just get the dealer to connect STAR and check the codes. It is hardware too, not just software. Many people here have cheap copies from China. The original dealer level stuff is thousands. The knock off is in the hundreds. Shardul is a forum member and vendor who can get them. I would run codes at the dealer and then report back before anything. No point doing a fluid flush if you have to go back in again to replace something or get a rebuild.

E55 Gearbox is a 722.6 I think.

If yes, changing the fluid is easy if you can get access under the car. You will need to buy the dipstick as well as the cover which is one time use. Be sure you respect Mercedes specification for your transmission (Follow this link to find out which specification: http://bevo.mercedes-benz.com/bevolistenmain.php?content_action=showselect&navig ation_path=bevolisten&language_id=1&blatt=231.0&su chbegriff= if 722.6 is confirmed, then you have to use 236.14 oil, here is the choice you have http://bevo.mercedes-benz.com/bevolistenmain.php?content_action=showselect&navig ation_path=bevolisten&language_id=1&blatt=236.1&su chbegriff= )

You will need to remove the pan to get access to the filter. It MUST be replaced at the same time than the oil. At this occasion you will check is any metal is on your pan or on the magnet.

With 125k, it does not hurt to change the oil anyway.

Now it looks like you have 2 problems because the gearbox is not going to switch off your compressor. This sounds more like the pump, also very easy to replace.



And by the way, the compressor oil is also supposed to be "lifetime" ...

As for your second question, its definitely your ic pump.

SilverDameon55

Alright so I just got home from the stealership...had a 10am apt and didn't leave till about 4:30pm. Did the tranny fluid, filter and seal which the guy said the fluid looked good and didn' really know why I wanted to change it.....also ran the STAR program and 2 things came up in the red:

- RO Line: Charge air cooler circulation pump & coolant
- RO Line 2: Charcoal canister shut off valve.

The dealer wanted to charge me $1395. For just those. The coolant pump part number the lady gave me is 000-500-03-86-80. Is this the I/C pump?

tw2

Glad you have no transmission codes! Yes sounds like the intercooler pump- other numers are A0005000386, 0005000186, 0005504883, 2305000086. It is $112 from FCPeuro and the DIY is in my signature.

Years ago, DBAG introduced a new model line (210s?) and decreed that transmission fluid should no longer be changed. It was designed to last "a lifetime". As many owners found out when their transmissions failed, that was a cruel joke. Changing every 30,000 miles is cheap insurance. These same Stuttgart geniuses took out the oil-pressure gauges and the engine oil dipstick...

SilverDameon55

I'm for sure going to check out the pump on that site and attempt to do it myself. I may have to purchase some more coolant though correct? What is the charcoal canister and is it something I need to change asap?

SilverDameon55

Is this the part I need?
