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.
Rough Shifting of Automatic Transmission on Mercedes-Benz GL450

Have owned over 40 cars in my life from Australia, London, USA,, never have I experienced this concern in any car previously. Extremely dissappointed in the Mercedes GL 450 quality and technology, this is the 4th. mercedes vehicle, others were cars not SUV made in the USA., absolute rubbish. Cost to repair approx. $6,000.00 that's why it sits in my garage for 12 mths.. Most certainly never purchase a Mercedes Product again. VW's are better quality.

The transmission has been slipping since it was new, rolling back on hills like it was a manual. I have reported it since day one and they couldn't find anything wrong. It had a technical service bulletin on an electrical component outside the transmission performed in 2007 but nothing else. It now shutters, they say I need a new transmission and of course its long out of warranty. I've called mbusa and they don't want to hear about it because its out of warranty.
After I started my Mercedes GL450 and changed gear to drive, noticed roughness in driving. Pulled over and put the car in park and back into drive. This time it would not move. It seems it got stuck in nuetral mode with no indication what so ever on the dash board or anywhere.Had it towed to the dealer, they informed me that the automatic transmission pump is bad and they saw metal shaving in the transmission pan. The fix is to replace the transmission. They could not find the cause. They did aknowledge that there is an internal component failure. I called MercedesB USA, they informed me that they had no recall on transmission issues. How can I follow up on what you had stated that Mercedes released updated parts; the transmission will need to be removed and disassembled to complete the necessary repairs.

My 2007 GL 450 is having shifting problems, It either is stuck in gear or will not move, causing to restart the car to clear the problem. I had to take the car in to get a new sensor plate 1300.00 repair bill.

Transmission oil drained out on own accord. Previously gear stuck and will not change down. Have owned over 35 cars in my life and never once had a similiar problem, should think that being a premium vehicle manufacturer, Mercedes would issue a RECALL on this concern. Will not most certainly purchase a Mercedes again, this is the 4th. one and the last one. No different from the mass manufactured garbage made in the USA.

First trip to Dealer in Jan 2015 for rough shifting. They kept the car for 4 days and updated and re-installed software. It seemed better. It's now May 2015 and it is still shifting rough. I'm making another appointment as it is still under warranty. If they don't fix it this time, I will sell the vehicle.

Vehicle will not accelerate from a stop, resulting with vehicle crossing the intersection for over 1 minute with a near collision.

There are times that my shifting is so rough. We experience it when it is down shifting. How I feel it is engaging the gears so roughly. I have it checked but ofcourse once they plug in thru the obd they wont find any codes so they will just say "nothing is wrong"

Vehicle shutters and hesitates when driving at low speeds or up hills.

After long drives on the freeway, the car will accelerate slowly. It seems like there is a bit of hesitation between shifts. After driving a bit it will solve itself, but the problem is becoming less sporadic and more common. It is an automatic transmission.

They just get a clog or choke in the gear shift up or down

I recently purchase used 2010 GL450. I notice the hesitataion in shifting mostly when after the vehicle has warmed up. It was sporadic, but I have noticed that it is lasting longer and longer and happening more often.
