my wife's car, 260E has developed a transmission leak. my mechanic says it is coming from the torque converted whereby the transmission has to be taken down, sealed replaced, etc. His worse case scenario is I might need to replace the transmission altogether. Isn't that a big jump from a leaky transmission? Do I really need to replace the transmission or the mechanic? Your guidance, please?

Joel,
I just finished replacing the front seal, flex plate, and torque converter in my 300SD. It was time consuming, but not that difficult. Mercedes quoted me around $1300.00. I was able to do it myself for about $450.00(this included some new tools I needed). Just a bit of info. By the way my car now runs great, no more clatter or leakage. Best of luck.

Hi Wing_Nut!
Just wondering if you used OEM or aftermarket parts? If aftermarket, which supplier did you use? Regards, Nick |

The front seals and o-rings are cheap. Use factory seals. The leak is the front pump seal, not the torque converter seal in 99% of the cases I have seen.

Nick,
My situation is a little different than yours. Like BenzMac said the majority of time the leak is from the pump seal. Mine was caused from the converter seal due to missing bolts in my torque converter, and thus causing the TC to wobble. However, I believe the procdure would be the same for you up to point where you would install the new pump seals. I took BenzMac's advice and ordered a remanufacture MB torque converter (the dealership wanted $950 for a new one) the seals and bolts I purchased from MB. I did this because I wanted to ensure that I had the right quality parts so I wouldn't have to do it again. I probably would have used the parts shop but this was on weekend and I wanted to complete the job. Costs Reman TC w/ 1 year waranty $225 New TC Bolts and Flex plate bolts $45 Transmission gasket & TC seal $40 Fluid $10 Flex Plate from MB $33.95 Misc tools $100 (needed an excuse to buy them anyway.) Best of luck to you. And rember if you do it your self take pictures of use a mini tape recorder so you put it back the way it's supposed to go. And don't forget your torque settings.

Just to avoid confusion, I think Wing_Nut's post above is addressing Joel.
Thanks everyone for all the useful info. |

Yes, I was confused on my reply. It was Joel's reply I addressed. I guess I read to quickly, then again they never said you have to be smart to be a US Marine.
My apologies. Peter Kalloday ------------------ Wing_Nut 82"300SD |

Wing_Nut:
again, many thanks for your reply. honestly, i wouldn't have your courage in doing what you did with your SD. right now i am looking for an independent MB shop in my area to work on my MB's transmission leak. incidentally, i lived in the Kirkwood area sometime ago. how about 'em Houston Oilers (now Tennessee, what?) but my heart bleeds for the Rockets!! regards. joel [This message has been edited by joel (edited 01-20-2000).] |

The most common leak I find coming from the front of MB transmissions is the O-ring around the front pump. This requires the work of a Quality tech. Make a few calls to some independents and you'll likely get the best deal.

Any of the above interventions require the tranny to be out of the car. BTW, where do you see the oil coming from? If it's the bottom of the bell housing, all of the previous recommendations will apply. If not, you may just need to replace pan gasket, dipstick o-ring, output flange seal, none of which require removal of the tranny.
Good luck. Drive train stuff can be a bummer.. ------------------ Jeff L 1987 300e 1989 300e |
