Hi Guys,

As per my previous post, I found a small patch of Tx. oil on my garage floor after the Tx oil change at the indy shop (MB specialist they said). I do not have enough time to go back to them yet to check leak. Mean time, last night I measure the oil level with the special dipstick and found it is overfilled. when the temperature is 77F (25C) in my garage the level shows 80C lower marks (engine cold). Is it tooo high? I have only driven 100 miles or so after the fluid change. Is there any possible extensive damages? what is the possible place where the excessive oil dropped out? what will be the worst scenario and what is the best approach to these idiots?
Please help me with your advice that I am planning to take day off and go to the shop tomorrow.

doesn't seem overfilled to me....if it is a little you can drain... i think you have to have the engine completely warm...and the car level to do the check...

i would be more concerned about the puddling.....

it would be pretty easy to suck some of the fluid out....or drive it to the indy...and let him re-assure you that it is filled correctly.... i would have him put it on the lift as well to try to identify the leak source.

Are you checking the level with the car running? If yes, then it seems to me that it is obviously overfilled. Transmission fluid expands as it gets hotter. The special dipstick measures from the bottom up. It has a marked band for 20 deg C and a marked band ( range ) for 80 deg C. The band for 80 is higher up than the band for 20.

If the level is at 80 band and the temp is at 25 C then you have a problem.

The next question is whether they used the correct MB synthetic fluid.

Sounds like your ATF is at the wrong level, but the only way to check properly is with the box at normal running temp. after at least a 10 mile run, measure on level ground with the engine running and gearbox in Park.
As said go back to whoever changed your ATF and have them check the level and the source of the leak, but don't go with the attitude that they are idiots , just ask them to reimburse you for your expenses if the fault is their's.

Thanks for your replies.
I measured it when the car is cold and the engine is not running. I am aware that it should be measured with the engine run and when hot at 80C to get the accurate level. But just to confirm whether it is overfilled. Now I am afraid of warming up the car that the fluid will expend too much to damage oil seals.
Correct me if I am wrong. In my above case the level should be shown just above 25C marks. Right. It is now showing all the way up to lower 80C.
I told them to use MB fluid only the boss assured me that he had to use it.
Thanks again.

Start your engine with gearbox cold and check your fluid level, I think you will find the level will drop to the lower marker range. You won't damage your gearbox in the short time it will take to do this.

You can't measure your fluid level with the engine not running. Will not work and measurement is meaningless.

Steve

Thanks for all of your advices and immediate helps.
I learn something new again today. This is a great forum.

Of course it's high when the engine's not running -- fluid that would normally be pumped throughout the tranny and cooler is now sitting in the pan. As indicated earlier, start the engine and check the fluid for the cold level. Then drive it for at least 10 minutes, and check it for the hot level.

You may find that the "idiots" did it properly.

This is the main reason MB no longer fit dipsticks to their gearboxes !!!!.

"You may find that the "idiots" did it properly."

Sorry, my apologies.
I feel quite upset when I saw a Tx oil puddle on the floor.

Just curious. Exactly what is a Tx puddle? Tx means?

Steve

Transmission. Lazy to type whole word

Ok, got it.

Here's something to be aware of. This may not apply to your specific transmission, but it could.

On the 722.6 transmissions there is something called a Data Plug Spacer that tends to leak. It has been recommended by shop mechanics on this list, that this part is / should be routinely replaced.

The part costs $6 - $8 at the dealer, and is a 5 minute job.

There was a post yesterday detailing how a dealer charged the poster $116.00 to replace this part.

You may want to ask your shop whether they replaced this part.
