Am I correct in assuming that your mechanic took your engine out to repair it and seperated it from the gearbox?

If so, the problem will probably be the gearbox front pump seal which has more than likely been damaged in the process.

If he has replaced this each time and it is still leaking, check the torque converter where it sildes into the seal to make sure it has no burs which could be ripping the seal.[]

Oil Leak

Yes...you are right. This is what exactly happend. I was there when they were trying to fix the engine in the body it was not aligned with the gear box, at that time they pushed it very hard into the gear box which made a big sound. I asked him about that noise but he told me there is nothing to worry about.

Oil leak

I am beginning to doubt your mechanics competence.

If the engine and gearbox were not aligned correctly and forced together then all sorts of damage could have been caused to the internals of the box.

Do you know whether the torque converter was seperated from the engine when the gearbox was seperated or was it still bolted to the back of the engine when they were seperated?

I am new in Saudi Arabia and finding a good Mercedes mechanic is very difficult, there is only one big workshop and showroom but they are very expensive. So I took my car to a common workshop and I think they are not qualified mechanics for Mercedes.

If torque converter is the big donut shape thing, It was bolted to the engine when they separated the engine firstime and the time when they were trying to fix the engine into gear box. And each time when they were separating the gear box, it was not bolted to engine, they they took it out with the gear box.

Re: Torque converter

The torque converter should be unbolted from the engine when they are seperated. This could also have caused damage to the transmission.

Unfortunately I cannot accurately predict what the damage is. At the end of the day, the mechanic has caused the damage, but it appears in your case that he is trying to avoid the blame and make you pay.

You have four choices.

1. Leave the gearbox with the mechanic until he fixes it but he may never fix it properly from what you have already said.

2. Take the car to gearbox specialist and have them fix it.

3. Buy a secondhand box.

4. Have the gearbox examined by MB or a gearbox specialist, get the fault identified and priced. Then contact your mechanic via a solicitor if needs be and tell him you will sue him unless he pays.
