Car Forum / Mercedes-Benz Cars / June 20077-speed transmission troubles
I own an '06 E500 with the 7-speed transmission. I bought the car new in Dec. 2006 and have 1200 miles on it. The car runs great with the 5.0L V8, but the transmission seems to have a mind of its own. It never seems to be in the right gear, it often hunts for the right gear, and it sometimes clunks slightly when engaging first gear coming to a stop. The car was built in Sept. 2005, so I'm wondering if it might have a late-05 or early-06 trans. Several publications have mentioned that M-B has had problems with this trans, but I can't find *any* posts here that mention these problems. It's hard to find M-B tech. service bulletins online. Is anyone aware how widespread the problem is, and does anyone know what the M-B response is? The car is obviously under warranty, but I would appreciate learning any background about transmission troubles in this car before approaching my service manager. Thanks in advance. John E. I've found that driving this transmission with vigor - as one with a E500 probably would - it WILL downshift into first with a bump/clunk. Driving it gently, however, it will be completely smooth and unnoticed. It has an adaptive driver logic designed to reflect the driver's actions and one ought to pick a camp - cowboy or old fart - like me! It it will perform accordingly. Good luck with your car.

I had one for my 2005 SLK350 concerning the manual transmission where I felt resistance going into 1st occassionally where if I applied more pressure would "slip" in reverse. The TSB stated what to do "that if a customer states" for it but since they could not it they refused to fix it & that was with the factory rep who was completely useless as he took a ride with me for it & we both noticed that other repairs that were claimed to be done by the tech were not. The reps answer was make another appointment, did not ask the dealer why the tech lied. If you want the name of the dealer & rep let me know. >I own an '06 E500 with the 7-speed transmission.

The first step is a software reprogram. That didn't help mine. The next is a valve replacement; that fixed mine. The dealer said if that didn't do it, they would replace the transmission. Mine was downshifting very aggressively when I slowed down, slamming into first gear with a lurch. I found others complaining on some MB forums about this too; I printed those out and took them to my service advisor. > On Jun 24, 2:59 pm, do_not_rep...@mail.com wrote: > [quoted text clipped - 14 lines] > > > John E.

The old 5 speed worked great, and was better than the Lexus 6 speed. That makes me feel a little bit better about not having the wonderfull S Klass - I was forgetting just how bad it is to have to drive into the dealer every trip out of my driveway. mcbrue kudzuly under the bridge in the trailer down by the river > WOW !!!!!

You own a Japanese Cadillac and you are now lonely with too much time on your hands.
