Exclamation Screwed-up ATF Change at dealership, help!

hello guys,
it's not an emergency, but a question for you how to find justice with the dealership.
yesterday i was changing ATF on Mercedes 300E 1989,
i have provided the ATF Fluid (Mobil 1, 8 quarts), as i know, the capacity of my car is around 8 quarts. After i got my car back, only at home i have noticed that they used only 3,5 quarts of fluid. I called them and they did confirm that they haven't drained the torque converter (even though i have a plug there and i know that it is supposed to be drained), also they told me that they never actually drain the TC. So i said goodbye and decided to research before demanding something . Is the TC and transmission pan a closed circuit? Can i call them and demand to drain the TC or refund my money (150$), i didn't do it myself only because i wasn't sure how to drain the damn TC. But paying 150$ for just draining the pan thats hideous!

Please share your advice with me, what should i do?

thank you in advance,
andrei

Sounds like they took you to the bank. Removing the TC drain plug is not really any harder than removing the tranny pan drain plug. I would try to get some of the money back.

Not clear what you are really asking. My guess is you mean to ask whether the fluid in the TC is separate from the fluid in the Transmission. No the fluid flows between them. If they were separate there would have to be two fill tubes.

I would take the pdf in post 3 along with 5.5, 6 or 7.1 qts of new fluid which I had purchased (your guarantee they use the fluid you want) to the service manager and request they drain everything as they clearly should have done and refill leaving the new filter where is.

Little give/little take.

so let's see, you were smart enough to buy 8 qt's of mobil1 fluid, and you even knew that you had to drain the pan and the TC, but yet you took the car to the dealer only to be rammed in the a$$ ?? what a pity

I'm a medium DIY'er at best and this is something you can do yourself. Since they already did the messy part of changing the filter, you can drain the trans and the TC and just refill. You can search this site to find where the TC drain plug is.

Of course this assumes you have somewhere where you can work on your car. If that's not the case, I would just take it somewhere else and tell them exactly what you want them to do. I'm not sure how productive it would be to go back and argue with them but if you've got the time, you've got nothing to lose.

IMHO, there are two ways to handle this problem. The dealer charged you a fair price to perform a relatively simple job. They only completed part of the job, so they either owe you a full refund, or they should do the job correctly.

FWIW, the simple maintenance jobs (oil changes, transmission service, etc.) usually go to the least experienced techs'. The whole thing may have been an honest mistake. It's possible the guy who worked on your car didn't even know the TC had a drain plug.

Unfortunately the last comment was right.
You never know what tech you are going to get at the dealership, and if the kid even knows what a torque converter is.

Dealerships are scary, I know I was a tech at a couple.
I could tell some horror stories about some of the things new techs do ,and don't do, corners being cut by experienced techs which is what probably happened with your car, although and experienced tech would have covered his tracks better by hiding the unused customer supplied trans fluid so maybe your tech was just plain retarded, who knows.

I would take it back, talk to the service manager, demand that they drain and refill the fluid from the pan, and torque converter and replace the filter with a brand new one.
They'll take care of it, all you have to do is tell them you will make sure everyone knows how crappy their dealership is if they give you any guff.

No service manager wants to hear that.
They may have been a little insulted by you bringing your own oil, but at least they could have made you happy by doing the required work since you evidently seemed like a more discerning customer than most.

Some of the cars in that era did not have TC drain plugs. I know my '91 300SE does not. Does anyone know if the '89 300E has one for sure?
I'd hate to see you go in all set to get redemption, and instead get zapped!!!

Andrei has every reason to question the quality of the work done on his car, given the fact that more than half of his ATF wasn't used. It's not about "redemption", it's about getting the job done correctly.

Some Forum members may be surprised to know that the dealer may actually appreciate the feedback. If it was, in fact, an honest mistake by an inexperienced technician, he needs to be told about it. If he's not, it's only a matter of time until he makes the same mistake again. If it turns out that the technician didn't give a sh**, the service manager will definitely want to know about it.

Lastly, there are some dealers out there who don't work on cars that are more than ten years old. But believe me, those that do are keenly aware that owners of older cars have plenty of options when it comes to routine maintenance. The way the business is today, dealers can't afford to look the other way when quality issues arise.

hello guys,
thank you for all your replies.
here is the story.

i have also called the other dealership and they told me that they don't drain TC as well. I took the print-out from the post earlier and my work book (bentley publishers) where it clearly says about draining TC and went to the dealership. Right away i called the service manager and was ready to argue. But, they he was so extremely nice, he took me to the shop and there was several mechanics (older guys, looked like they knew what they were talking about). And we started discussion. One of them explained the reasons for not draining the TC because there is a pump right before the TC, so if you'll drain the fluid from there, after starting-up car the TC wouldn't be filled-up and you'll get some 'metal-on-metal' action. But i did show them all the manuals and how it should be done. They said that they'll do it but it would be first time ever they'll do it on 300e. As i said, they were extremely nice and friendly. I though for a while and decided that if it works fine right now, and they have never done it in their lives, i would just leave it like it is and change it myself in the summer. The only thing i'm pissed off at myself that i spend 150$ for nothing...lesson learned.

All of the cars from the era have a TC drain plug - including your 91 300SE.
