i have 2006 slk 280. the car slightly jumps or do not ge to smooth stop when car is between 5-0 mph. this happens when engine temperature is below 60C. I notice this because we are under 32C t

think you mean F on C if C, boy howdy you live in the tropics- 60C=140F 32C=93F so maybe it's frosty not steamy?

Bet if you allow it to come up to operating temperature at the outset you will not have this problem anymore....betcha~

That Slk probably has the dual clutch 7 speed transmission. It's used in other cars and has the same low speed thud. Mercedes may have a software change to soften the blow. Check with your service adviser next time into the shop.

Dear Tenspeed, I took the car to mercedes shop, they did no t mention anything about the probelem. well of course the car is in operating temp of 85C.At 85C the car works fine. Than you very much for the input. I will mention the software. I hate going to Mercedes dealership in my area. they are scum!!!! and dont want to look stupid. you know they dont think women have brain !!! To judge Roy, I do let the car idle for 5 -10 minutes, it only get to 50 C and it sill jump or thump. May be i have drive around parking lot to warm it up. Oh temp here ion the south this time is 26 F not C. sorry for the error. Thank you for your input slk_53

thank you all very much for your answers. Yes i will warm the car to alleviate the nod. Not sure how to ask the dealer about the computer program to help the speed. Our dealer here in my are is not necessarily friendly especially to women. I am in the south and our temp her now o 26F not C contrary to what i posted earlier

Before you go to the dealership for service, check out what other owners are saying on MBSLK forums. They sometimes know about the problem, the technical service bulletins (TSB's) and maybe what mode to drive in to lessen the thud.

thanks. very helpful. The TSBis that part of the owners manual- i dont know where to access one. can i download the bulletin. There is a fee for it? It will be worth iot.

sorry for typo, i meant i the feeto download TSB will be worth it

Technical service bulletins (TSB's) are published my Mercedes and used by dealerships to repair known problems in their products. Usually the repair are free to the customer. They are correcting design errors made at the factory.

Thanks for the comedy and BS about TSB's, dual clutch transmission, thats a good one! Here's the correct answer; what may be the (but most likely) is the problem is the transmission oil is contaminated with glycol from the radiator (as the trans. cooler is in the radiator). The most obvious symtom of this problem is a harsh 2-1 shift when coming to a stop. The MB shop can perform a glycol test on the transmission fluid and depending on the amount of contamination you will need to replace the radiator and have the transmission flushed at best. Torque converter replaced, transmission overhauled at worst. The dealer will have a bulletin about this problem, but unless you have extended warranty it'll be expensive. Push them to offer "goodwill" if all your services have been performed at an MB dealer.

thank you very much for your reply. Extremely helpful. Regret to say, no extended warranty

ow, i have to check with dealership in town if they will believe me about TSB and defects of the product. I am sure there will be no acknowlegement of fault. I will give it a try.

yay~

"Rough Shifting of Automatic Transmission -- Drive Train -- Verified Vehicles equipped with a 7-speed automatic transmission may develop a rough shifting condition, most commonly going up from first to second gear and going down from third to second or second to first gear. Our technicians tell us this is due to an internal component failure. Mercedes has released updated parts; the transmission will need to be removed and disassembled to complete the necessary repairs."--- http://repairpal.com/mercedes-benz/slk280
