Mercedes-Benz CLK-Class - Mercedes CLK 2003 - transmission problems - itsjustrobbieok
Hi, every time I've had a car problem it's been solved by this site so thought it's time to sort out with my latest car issue.

I noticed a bit of a whining noise a few days ago (could have started longer ago, but music drowns it out) happens in neutral or in gear and gets louder with revs (no noise when idling)

This evening whilst at traffic lights I put the car in neutral and then when I went to put it in drive - nothing happened. Turned the engine off and back on again and it went into drive ok. The car then went into limp mode not going past 30mph and not letting me use the semi auto gears.

After I got to my destination the car was left for 20mins or so and on starting again it allowed me to use the gearbox normally. A few miles in to the drive home however it went back into limp mode and the engine management light came on. Car as before would get me to about 30mph until the very end of my journey where I got stuck at the bottom of my hill - the car revved but had no pull. After leaving the engine off for a minute I was able to limp up and home.

Just before xmas I had the ac compressor replaced, no other issues though in the year I've had it. Mileage about 140k - it hasn't had a service in about 2 years.

How terminal does it sound?

First thing to check would be the trans fluid level.However ,there will be a dipstick tube but no dipstick.You will need to find an MB specialist that has the correct workshop dipstick.
