Metal Particles in Transmission Pan

I had the transmission serviced, on my 1982 Mercedes 300SD, and the shop reported that there were fine, free, metal particles in the transmission pan. They said that this meant my transmission would need repair within maybe six months or less. My car has 248,000 miles on it and the bands, when cold do tend to slip a bit, but when warmed up, I notice no further slippage. Is their report consistent with what I should expect?

What are my chances for my transmission, in you opinion? The shop said that its' rebuild would cost about $ 2,600 dollars.

This seems a bit much in my opinion. Please advise.

I had the same problem with my transmission. The previous owner never changed the filter. It appears to be a non problem for me at the moment. These transmissions start to slip when the transmission filter plugs up. I suggest you do what I'm going to do and change your transmission fluid and filter early. I'm going to change mine at 15,000 miles instead of the 30,000 .

It's just clutch material, normal to me.

It may blow, its real old and the particals in the pan are not a good sign, throw in the slipping. A rebuilt trans should cost about $1,500+/-. Throw in another $500 maybe if you pay someone to swap it.

Their report is consistant with a shop that needs to do complete transmission overhauls to make money.

Most M/B transmissions are on borrowed time after 200K. There are exceptions and the maintenance of the unit coupled with the driver can extend this interval.

There really is no way to determine when the trans will slip to the point where you cannot drive it. It could be six months.........it could be another 50K miles.

Shops see M/B owner coming..........they have a parts cost of about $500 or so.......the remainder is whatever they think they can get for labor.

You can purchase a very good overhauled transmission from Sun Valley for about $1300. or so with shipping. Then, you simply need someone to R & R the unit for you. The job can easily be done in 5 hours by a trained mechanic with a proper lift. So, another $500. is perfectly reasonable.

I concur with BC on this. 200K is getting there... both of mine shift well but leak (not sure on the 420, it's not running). Common on the 722s. I've been quoted about $200 for a reseal job which is reasonable IMO, but since I plan to keep the vehicles... may as well go through it while the unit is out.

Keeping the fluid with filter changed 25-30K along with driving in 3rd around town helps keep the wear down by a good deal. No 3-4, 4-3 shifting constantly.

$2600 for a reman unit installed is nuts. You receive the Mercedes tax and it better have a SERIOUS warranty for that amount of green.

I replaced mine at about 275K, but it had been flaring for a while. That seems to be just about their life expectancy.

Personally, I would put a known good used unit in. I did. I paid $400 for it and did the R&R myself. I am going to try my hand at transmission rebuilding on the old unit sometime. I hear the 722 is about the easist AT to rebuild in the world.

Yes, it's very simple.

They typically take a moment to engage. The thing about it happening after a turn and the clunk and wheel chirp makes me suspicious of your differential or U-joints from my experience with other cars

The clunk may be related to a CV joint (or, less likely, a differential), but the "slipping" has to be related to the tranny.

Yes the leaks. Mine shifts fine, well it will once I get the vac sorted out. But it won't stop leaking. I think my recently replaced front seal is at it again.

I suspect a certain percentage of these trans get rebuilt simply because they are 20 years old and won't stop leaking!

My SDL leaks about 1qt in 1000 miles, like the motor (damned leaky turbo).
