Of course there is no dipstick to check the condition and levell of the fluid. So do I have to just drain it out and refill or is there a trip to the dealer to do all of that? Is there a special type of fluid MB transmission fluid or can I use something else? If anyone here with prior and expert opions that I WELCOMCE could tell me it would be greatly appreciated....

Re: Transmission Fluid change

Your '98 is nice in that it should still have the torque converter drain plug. That way you can get nearly all of the fluid out. As for the correct fluid, use whatever is spec'ed for your transmmission and listed as approved for your transmission in the owner's manual. I think '98 may have been a transition year. Could be regular Dexron III or it could be the Mercedes only synthetic fluid. Dipstick can be purchsed on e-bay for about $30.

Re: Transmission Fluid change

I have changed the transmission fluid on my 98 c230.

There are 2 ways to approach this.

1. order the proper dipstick from MB or any other mercedes parts supplier.
The dipstick is really just a measuring tool and does not stay in the car.

2. drain the fluid, measure the amount and then refill with the exact amount.
The level should be close enough.

The dipstick is not that expensive so I'd just pick one up and then you can
service your transmission with out any questions to the level.

Re: Transmission Fluid change

Thanks guys, I was under the car yesterday at my exhuast guy. Had cut off the two usless cats and the other muffler, it sounds and looks alot better. While under there, I saw the pan for the A/T. It didn't look like there was a drain:mad:. So I guess that means dropping the pan and changing the filter when I'm under there?. Or is there a majic place where there is a drain that I didn't see???? And another question. I see the dipstick were its supposed to be. For the second looking at it, she seems not to be wanting to be removed.:nono:

Re: Transmission Fluid change

There should be a drain plug.

on my car it is a flat plug that uses an allen wrench to remove.

Jake The tube for the dipstick should have a round cover on it, It comes off easily. :smilie:

Not sure what your mileage is but as long as you're going this far you might as well change the AT filter and put in a new pan gasket. We put in a new oil filter every time we change the oil. Shouldn't we do the same here? Besides, dropping the pan allows you to see if there is anything in the pan that shouldn't be there. It's an easy DIY. Just don't over-torque the pan gasket. :grin:

Re: Transmission Fluid change

The car has 106,000 miles. Whenever I buy a used car I change all the fluids and filters. I have been so busy with my business I havn't really been able to go out to the garage and work on this car. My wife and I are in the process of replacing our Ford F150 with a new F250 tow truck.....:Wall: Thanks to all of you guys for the great info.....

Re: Transmission Fluid change

The good thing about being a Member of The MBCA, you can get deals at the dealership. I negotiated a tranmission fluid change, along with the filter and reseting the computer for $200.00. That is using the synthetic fluid. Doesn't hurt that I also gave them a handshake deal to take care of customers flying into Manchester NH airport a months worth of FREE rides to the dealership that is about 3 miles from airport. One hand shakes the other........

Re: Transmission Fluid change

Aristocrat Motors in KC does a complete synthetic oil change, Fleece filter and 27 point check of the car for $59.95. No appointment necessary. I think it's a loss leader since that 27 point check usually turns up something expensive that needs doing...

They also give a 15% MBCA discount on all parts, labor and accessories, which is where I really get the big break! I save my membership fee x10 almost every year.

Does Aristocrat give first year membership to new Merc buyers? I bought mine at Scholfield in Wichita. At the time I purchased, they didn't but did give you an application brochure. They now give the first year of MBCA membership to all buyers. I believe they do the same for Porsche buyers.

No. I wish they did; but I am very happy w/ what they do do. I'm aware of Scholfield's plan, but it only helps the Wichita section for one year. After that most never renew their membership.
