I'm the original owner of a '99 C43. I've adored the car since I first put ass to seat in 6/99. I've got 103K miles on the clock, and the car has been used the way it was intended to be at every opportunity. As a former pro-stocker (raced a 426 hemi 'Cuda in another lifetime,) I surely know how to treat a performance car, and I've spared no effort in my religious maintenance of this road rocket. Never had a problem in 4.5 years--until today. History: At 65K I brought the car in for service and instructed the advisor to also drain the tranny and change the filter. Got an argument from the guy because he insisted that the tranny was designed to "never need servicing." He also lied through his f***ing teeth when I insisted and told me that there WAS NO filter to replace in the tranny, there was no way to drain it without dropping it (no drain plug,) and that the synthetic fluid was engineered to never need replacement. When I asked him to do it anyway due to the effect of heat and high-speed driving, he refused and summoned the service manager. They both then proceeded to make me feel like an outdated old moron, out of touch with the new tech level of their vehicles. What a crock! Today, with nary a warning, the tranny wierded-out in a parking lot, dropping in and out of gear, making sounds like the planetary gears were going to come through the floorboards, and grinding like an S.O.B. in 2nd and 3rd gears. Took her straight to the local dealer, where a drop of the pan revealed about 20 pounds of shrapnelized tranny parts--bearings, aluminum shavings, bands, gear parts, etc. The fluid was toasted, and there was the non-existent filter right before my eyes!

The $6,000 for a new MB tranny and torque converter is an expense that I intend to do everything that I can to craft into a suppository for MBUSA and Prestige Motors in Paramus, NJ. Of course Prestige tried to hide behind the "manufacturer's recommendations" line of BS, and MBUSA tried to blame Prestige. Point is, either they figure out HOW they want to pay for this repair, and in what proportion, or I'm gonna get a judge to do it for them.****ANYONE with this car--or any other MB with the "sealed" tranny (no dipstick to check fluid level, odor, or consistency) had better make sure that the tranny fluid gets changed along with the filter every 50K-60K miles depending on driving conditions. Listening to the MB line of dung can be an incredible migraine--one that hurts in other areas of the anatomy as well, not to mention your wallet!!! Anyone else having C43 tranny isssues?? LET ME KNOW!!! Class actions have a wonderful way of extending your warranty!!! Notice the one that got your engine covered for 10 years/150K miles about 2 years ago??? Act now, or you might be on your own when your turn comes!![8]

That would piss me off too. I was told by my mechanic that the "sealed tranny" was a crock. Plan on servicing at 40k. I did not hear about the engine warranty. Can you clarify?

Warranty Extension

Some dweeb in Pennsylvania used regular non-synthetic, petro-based, motor oil in his '98 C220 and seized the engine. He then filed a class-action vs. MBUSA for failing to have the owner's manual tell him and others to use ONLY synthetic oil, never the petro-shit, at all times. MBUSA settled, and a part of the settlement was an extension of the factory warranty on engines in their '98 thru '01 model years to 10yrs/150K miles for ALL MB owners. They notified me in the mail in May 2002. I thought that this only applied to the C-class, but on my call to MBUSA customer service this afternoon, a Mrs. Clarke let it slip that this applied to ALL MB engines in that four-year range. Good shit, huh? Get them to confirm it to you in an Email and print it for your file. You should have received the notice postcard, but I've heard from a few folks to whom this is news--seems that MBUSA conveniently F***ed up the mailing.

I'll keep you posted on my progress with the corporate ass-spelunkers.

While you are at it...

Check your car's front balljoints; apparently they can seize up, at which point the engine mounts come under unusual strain. I snapped one of mine; while MB (in the UK) wouldn't foot the bill for the replacement, it was very clear when the new mounts went in that the new part was a whole lot chunkier than the original.

I think my car got new tranny fluid at the 60,000 mile service, but only because I took it to an independent who specialises in transmission rebuilds as a sideline to his main MB business (George Fraser in West London, for all you UK readers). There is, in my view, no point in taking your AMG Merc to a Mercedes dealer; they have no idea what they are working on, and MB UK won't honour any warranties anyway.

Compare this behaviour with BMW and Alpina: BMW dealers have to get a separate Alpina accreditation. By contrst, MB UK sacked all their dealers and "invited them to reapply": hey presto, all the experienced mechanics leave and set up independently.

My tranny also went bad at 80,000 miles. The first thing that a non-MB dealer mechanic asked me is did I have the transmission serviced. When I asked the service manager from a local dealership, they said that they've never heard of such thing, even with re-mapping of transmission.

I e-mailed MBUSA and did not receive any results. I was told to deal with the local service manager for MB, but he played totally clueless.

There is a warning...

But it is very subtle!"

Mine just went at 78,000. The only sign was a very faint loose ringing or rattling at idle in neutral, audible only when the door is open. Slip into R or D and it goes away; go into neutral and it's back.

Then a rumbling starts, and gets rapidly worse. it doesn't seem to be related to how hard you drive the car, or whether you are in S or W modes; all I know is, it's £1,500 to fix...

Ho hum! Just glad I caught it in the throes of starting. I would have been very very sick if it had tripped off once I was the other side of the channel tunnel!

C43 needs love too.

These guys must be born dumb... I just bought a C43 with very low miles, that had been sitting for 4 years. The VERY FIRST thing I did is to take the thing to an INDEPENDENT Benz repair shop and have them change ALL the fluids including of course, the tranny's, all with synthetic of course, and this in spite that the car had under a thousand miles and the engine oil had been changed only 300 miles before. Never heard of oxydation? . Mobil One in the engine, Mobil One synthetic trans fluid etc...
Now if ANYONE thinks that engine or tranny synthetic is going to last 50K miles, there is serious brain damage out there.

yea,i think benzini is right,you have to change fluids before it turns into water!
engine wear,trans wear comes from a loss of oil lubricant.
synthetic oils is the real thing,mobil one is recomended by amg.
the tranny oil should be changed every 40k,engine oil evey 10k.

RE: C43 needs love too.

I had already considered this and changed the fluids at my last major service, with my independent - who specialises in gearbox rebuilds, and who already totally transformed the gearbox in my 4Matic.

So, mine lunched on nearly new fluid. No wateryness required...

Kabooom.

Then don't be surprised if the tranny packed up even after you got the fluid changed. It does not matter if it is synthetic, anyone who does not service a tranny at at least 25K miles intervals is asking for it. Even at 25K miles, you can cut the filter and find a nice collection of metallic powder...
Just think, on the race car we change the very expensive Elf F1 synthetic fluid after each race, and that's less than 100 miles for the weekend.

Listening to MB recommendations is also very optimistic...

RE: Warranty Extension

So is this Warranty Extension applicable to the transmission, too?

Also is it for all cars ? even non starmarked out-of-warranty cars not owned by the original owner?

thanks

Having just bought a C43 estate with 116,500 miles I read your post & decided to have the transmission oil & filter changed - the oil came out a filthy colour & smelt badly - the specialist mechanic who does all my service work was not surprised & expressed amazement that Mercedes Benz do not recommend changing the oil on a regular basis. I looked at the filter but did not see any evidence of metal filings draining from it. I hope that I have done this oil change before any damage is done to the gearbox- will keep you posted.

I had the fluid changed; didn't seem to make any difference to the failure within a few thousand miles. From the pre-disaster noises coming out of the transmission, I would say it's a fatigue/detachment thing rather than a wear/swarf thing.

The 1999 C43 tranny is known to "granade" due to a very aggressive tranny chip. Usually around 60k-80k. To elevate this lots of C43's after they blow up the tranny get a software change. The 1999 C43 is faster than any other year C43. We have tested this against other C43's in the past and I have blown up our tranny at 64K. Extended covered this and the bill was $8K. I always get the tranny fluid changed whenever I can. Another car that like to blow transmissions is the S class. Again at around 60K.

MBUSA and most dealers know of this fact.
