Hey Guys!

I've a 2001 S500. I've noticed a light transmission slipp by higher speed. It usually happens over 60mph. When i drive on interstate, and i'm coming behind a truck or car and take off my feet from the accelerate, and after i step back on it, to speed up, the transmission slipps a little bit. Like when You drive a manual car and You push the clutch in and get the rpm higher and You let the clutch out quiet fast it seems the same.

Any idea what is it?

Thank You! I ordered transmission fluid for a flush, also the gasket, and filter. Any good DIY on conductor plug change? I did reset the tranny though today we'll see, but i'll definitely do the flush too, bc the car has 181.000 miles on it, and still runs like a dream
Thanks

There is a good DIY on Youtube. Just do a search it was not hard to find.

All right so I'm a little late with the write up but I guess I owe this much for the community...
so I bought 16 quarts of transmission fluid, new filter new gasket, new drain bolt bought a new conductor plug by the dealer and started the job. Never done any transmission work before on any type of car. I toke of the transmission oil pan, cleaned it, take off the valve body and cleaned/washed out the whole thing with electric cleaner, take out every solenoid and washed it out. Than I put it back together, filed up with oil started went through the gears slowly. After it was running for a while I took off the oil line what goes back to the transmission from the cooler on the passenger side of the car and attach a hose on the end and the other end I placed in a plastic bottle. I started the car filled up the plastic bottle with 3qt transmission fluid and shut off the car right away! Filled up with fresh 3qt fluid and repeat this procedure till the fluff what cane out in the bottle is nice clean red as a new transmission fluid supposed to be! After this I just checked if the transmission fluid level is correct and boom JOB DONE!

Shifts like a dream!

It took me 5 and a half hour to do it, but next time I think I'll be able to do it somewhere around 2 hours!

Thank you for your posts guys! I thought I can upload pictures that's why I wrote this whole thing from my phone and now I see I can't. .. ****
