5 speed auto won't shift into 5th
Hey guys, my 320ce rev 3500rpm at 100kmh on high way, and dont feel down shift or rpm rise when pull shifter from D to 4. One of my friend said the 5th gear on those transmissions might be electrical, but not sure.
Any ideas guys?

This is pretty easy to test. Most likely it is the shifter switch. Unplug the shifter switch and it is a simple toggle. You can substitute the switch for a standard one for testing. If this does not work to get you into 5th then it may be the seals in the trans. It is true that if you unplug the control unit that it should go straight into fifth. You can feel 4th for about half a second but it is pretty much straight into fifth. If this is not it then it is in the transmission.
The unit on the back of the transmission houses all of the 5th gear items. Everything before the rear housing on the transmission is exactly the same as a 4speed 722.3. The valve body is the same except the rear section that has the overdrive solenoid.
Even if you lost 5th you could drive it forever without it.
Do not try taking the transmission apart yourself. The rear unit has a sprag in it that takes an act of God to get back together unless you have done it before.
Good luck.

How do you have 5 speed tranny ??? 5 speed was introduced in 1996 model year. Even back home in Europe (I am European) the first year was 1996 for W210 model. As far as I know for the US market was the second part of 96 as 97 model upgrade.
Even for W140 (the top end Mercedes at the time) the 5 speed was not available till 1996.
So...would you be so kind to let us know how do you end up with 5 speed on 1993 320CE??
Your car must be the only one in the world?
If I am wrong, I will apologize but I never knew that they put 5 speed on a W124/93 model.

300CE 24V Sportline 1991
5 speed on 1991 300CE-24
Hello,
I have a 5-speed on the above. It's a Sportline and the transmission's worked fine until recently.
Mine now has the following symptoms:
1. Under normal acceleration, it selects 4th gear for, say, half a second and then shifts to 5th and stays there.
2. Change down only occurs to 3rd so there's a great deal of lag when accelerating again ofter slowing. Basically, it seems to be 'wanting' 4th, is unable to select it until one slows sufficiently for it to select 3rd. Then it's back to 5th, touching on 4th, as you accelerate.
Someone advised me to remove the transmission 'brain' so I did and the thing wouldn't start so I gave up on that.
Any other ideas one and all?
Best wishes from la France.

It's nice to have a vehicle like that, but if it runs into problems, looks like i am the only one to face it in north america~

Actually the 722.5 5 speed auto was available on many cars throughout the rest of the world on the inline 6 cylinders from the early nineties up to the 722.6 came out in the mid nineties. In the U.S. the 722.5 was only available on the s-class and sl-class. The 722.6 came out in 1996 on v8 models only and in 1997 for the rest of the cars.

W124 280E and a Mini R50
I just looked at the owners manual for my 1992 280E (UK model, 1992) and the 5 speed is listed for the 280E, 320E and 320CE.

Well, you are wrong. The 5 speed auto tranny has been available on the Old Continent for quite a while. I used to have a 320e and a friend of mine had a 280e with a 5 speed auto box....

The easiest way to confirm if it's a 5 speed is to look at the speedo. The 5 speed has 4 sets of markings (small yellow notches) that indicate the maximum speed you should go in each gear (1st, 2nd, 3rd and 4th; in 5th you can go as fast as you can make it). If it's a 4 speed it will only have 3 sets of markings.
The 5 speed (722.5) has an electrically controlled overdrive or 5th gear, so an electrical issue is the lost likely culprit. There is a solenoid which controls the 5th gear. Also the selector switch could be faulty.
I have an Australian delivered E320 coupe that came standard with the 5 speed. It does not have a selector switch.
