Report: Internal Component Failure May Cause Rough Shifting
Mercedes-Benz GL450 Problem
Average Mileage: 57,462 mi (5,700 mi - 125,000 mi)
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.

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.

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.

Transmission needs to be replaced (advised by dealer)

Issue does not occur consistently. It mainly occurs during city driving when breaking from 45 Miles per hour or so to avoid a ditch in LA roads. When it has to downshift from higher gear into lower gear, ending up in 1st or 2nd gear.

odd shifting in low gears at low speeds, only noticed when going up or down hills.
have not taken the vehicle in to be checked out.

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.

rough on down shift when the cqr come to a complete stop.
Upon hard acceleration, specifically when cold, first gear goes to 4000+ RPM's. The shift to second drops the rpm's to 1000 creating a lag and jerk before it gets to 2500 rpm's where second should have begun in the first place. Bringing to dealer. Will advise outcome.
