Transmission light problems
 

About a week ago the check the transmission fluid level light went on in my 1997 C230. It would go off for short periods of time but it would light up again. I added more transmission fluid and the light was always on. I bought a dipstick to measure the fluid level from the dealership and it turned out there was too much fluid in the transmission. I drained the transmission and added the correct amount of the fluid. The problem is that the light is still on. After changing the fluid I took it out for a test run and after a while it turned off. On my way home it turned on again. Can anyone tell me why this is happening?

it is some other light, i don't know of any mercedes that has a transmission oil level light, post a pic of the light so we can assist you further

Hmmm. Thats what I was wondering..... I have never heard of a transmission oil level warning lamp.

My 2000 Toyota truck however does have a automatic transmission oil temperature warning lamp and the completely redesigned 07' Toyota Tundra has a transmission oil temperature gauge. Seems most interesting.

thank you guys, you were right.. A friend told me that the light might be a transmission oil level warning lamp. It is actually the light for the coolant level. The level of coolant is where it should be and the light still turns on. For example I start the car once and the light is off then I turn the car off and start it again and the light is on. It also turns on and off when I'm driving. Probably a bad connection?

I'd be worried about your transmission. Setting the fluid level is not as easy as it seems, with the fluid level set properly with the fluid at 80C. The 722.6 is sensitive to fluid level, and if I were you I'd get to a mechanic with SDS and make sure that the fluid level is right.

And go to the dealer and order an owner's manual. It has lots of good stuff, including what the warning lamps mean, which might save you some serious headaches in the future.

On the light itself, on my 99 SLK230, which has practically the same engine, the low coolant level light can also be turned on by low windshield washer fluid level. I could never understand why but when the car was new, the dealer replaced two or three coolant level switches under warranty before finding out that either of the two things could turn on this light. After washer fluid was added, the problem was cured. If your windshield washer fluid level is low, add some and see if it cures the problem.

If it is the switch on the actual coolant level, it is fairly easy to replace.

I have the repair manual for the car which explains how to check the transmission oil level and i have the tool from the dealer and everytime ive checked it since i changed the oil its been where it should be. The C230 has another light for low windsheild washer fluid. I added more windsheild washer fluid though but the light still turns on and off.
