Todays question concerns automatic transmissions...

Who changes their own trans fluid and filter? Why do you do it? Some helpful examples;

I change my own fluid because...

1.)Perfectionist syndrome- the only way to know something is done perfect is to do it myself...
a. No bozo to overtighten anything because he has more braun than brains...
b. No bozo to leave something loose or missing because his attention was focused on what a great time he had last night...

2.)To save money syndrome- Money paid to overpriced/overrated technicians would be better utilized in the go-tank [fuel tank]...

I pay someone else to change fluid/filters because...

1.)I can't stand the thought of trans fluid running down my forearms...
a. Doesn't that stuff cause cancer?
b. I gladly pay others to do my dirty work!

2.)I am sorry but I do not know how to do it?!

Trans fluid and filter?

1.) What the heck is that?

2.)I thought only the engine needed fluid/filter changes...

3.)I just stick the key in and drive it! I do not know what makes it go or stop correctly! Why doesn't someone take the time to write a free book telling everyone how it all works?!

As everyone can see there is no right or wrong answer, just everyones valued opinion...

I used to change my own tranny fluid until I bought a car with the 722.6 five speed box. Now it's easier to set the fluid level perfectly using SDS. Given the price of a new 722.6, I won't take any chances.

On the 190E, I do it. It's messy, but not difficult.

I used to have an 88 740 Volvo Turbo, then an 88 BMW 528e on which I did all maintenance, including tranny fluid change. On this one, after everything I've read about the 722.6 tranny, I'm afraid I'll be going to the dealer for this particular maintenance item.

I do it because I can.

blackmercedes - I do not undertand do you change it yourself? and what is SDS and how it tells you the level? I also do have a 722.6 but I am cluless. I am reaching 100K Mi and was wondering when to change the fluid.
I know it is fill for life but what is a life of a car? I am under the impression it may be 120K mi.

I DO NOT change the 722.6 tranny fluid myself. I have the dealer do it because you should use the SDS (Star Diagnostic System) to set the fluid level with the fluid temp at 80C.

Fill for life is a relative term. You could leave it in there forever if you like. Most folks change their 722.6 fluid and filter every 100,000km's (about 60K-miles) or so. Some people have had great life out of their tranny without changing the fluid, but others have faced disaster. It's up to you.

The life of a car is 120,000 miles? Not a Mercedes! Care for it and expect at least twice that, at least!

Thanks to all who shared their expertise...

I do it myself but for some reason this is a job that I really hate, so it may be off to a mechanic the next time it's due.
