i know that the 400e has the first gear start and the 500e doesn't why is that wouldnt they put the first gear start in the 500e because its the high performance sedan. and other that that there pretty much the same.

Hi Guest !
Welcome to the 500Eboard forum.
Since its founding in late 2008, 500Eboard has become the leading resource on the Internet for all things related to the Mercedes-Benz 500E and E500. In recent years, we have also expanded to include the 400E and E420 models, which are directly related to the 500E/E500.

difference between 500e and 400e transmission

Maybe because the drivetrain wasn't designed to handle the higher torque from a high RPM 1-2 shift? They did put a transmission overload protection valve on the 2-3 shift. Or maybe it was for emissions or gas mileage too. A lot of the 500E's ended up being sold in California, didn't they? These are just guesses. I'm sure when Dave and Gerry wake up they will give you the correct answer. It doesn't seem to make much sense to me. For a while, I could not understand why the E500E guys were always talking about a first gear start modification when my 400E/E420 both start in first gear and they are 722.3xx.
400E got FGS because of the 2.24 axle ratio for USA and Japan models. The tall 2.24 gearing was a way for MBNA to avoid the gas guzzler tax in the USA. I'm not sure why Japan got the 2.24's. The 400E would have been a complete dog with 2.24 gears and 2nd gear start.
All Euro-spec 124.034 models came with 2.65 gears. Can't remember if they have 1st or 2nd gear start though.

ya i was just thinking that was the only difference. when there do a transmission rebuild what do they usually change. ya should like ill have to get a 400e tranny for mine.
Yes, you can read the complete number stamped on the passenger side of the housing, right above the pan gasket. If the trans had ever been rebuilt, it's also possible the rebuilder screwed something up with the valve body. You can also tell from the serial number vs EPC datacard if the trans is original or not.
can i fix w124 400e/420e transmission on w124 500e ? and there is a 5 speed cable transmission ?

Yes you can install a W124.034 400E/E420 transmission into your 500E. As a bonus I think you may also get first gear start (not sure on the Euro 400E/E420, but US/Japan .034's all have first gear start valvebodies.)
The 722.6 electronic five-speed transmission is not a simple bolt-in, it requires a standalone computer, and other modifications. $$$$$. I have not yet seen anyone actually do this on any .034/.036 but it would be pretty cool.

thanks alot gsxr,our parts here in u.a.e are from japan,thats mean it should start in 1st gear,i hear that the 4 speed transmission is more reabile than the 5 speed ,is this right?
Yes, if the 124.034 is Japan spec, it will have 2.24 rear axle ratio, and a first-gear start valvebody.
That depends. The four-speed tranny is more reliable than the 722.5 "mechanical" five-speed, which was used in some late W124's. However the later 722.6 electronic five-speed tranny is very reilable, but it was never used from the factory on the 124 chassis. It first appeared in 1996 in the W210, W140, R129, and maybe one or two other chassis.

If so, does it come w out the -->B in the selector? I've seen that I think, just curious,, Roger

thats mean if i fix 124034 transmission i shoult change the rear axle?what about the differential,speedometer?
No no no, you can use the 124.034 transmission in a 500E with zero modifications. It just bolts in. The 124.034 has different differential gearing, speedometer, etc but that does not affect the transmission internals (besides the valvebody).
I have a USA-spec 124.034 and it does have the -->B position in the gear selector. All 124.034/.036 chassis should have the same thing.
So which US year 400e's have the 1st gear start valve body? Is it best to replace the whole tranny with a 1st gear start or can you just change out the valve body?
I'd like to pull a valve body only from a scrap yard. Is is a straight forward valve body conversion r are there modifiacations to be made on the 400e valve body before putting it in the 500e tranny?

A couple of points here since there have been a few years since: I spoke with Hendrick via email at Elbe Engineering. He states that he provides all needed to adapt a 722.6.
When thinking about the why or why not of Mercedes Benz classic cars it has to considered what kind of company and what they were producing. think of why they made decisions to do certain things. For example all Mercedes Benz automatic transmissions prior to 1981 model year were 4 speed automatics without a first gear at all. think of the client who was buying these cars new. Everything about the cars were both understated and sensible. They set the standard for entire car companies to try to achieve. Think of the very first Lexus commercial. Also consider why they set the transmissions to shift so smooth. Mercedes today is all about performance and luxury. Not so before. Even when their very successful racing campaign of the early 80's C107 rally cars was told to make budget cuts the reply was, "Well with those cuts why not cut the entire thing?" Mercedes Benz did just that. They did not care about that. If you don't believe that my '91 500SL could have been made to whup everything... well they did just that when they made the W124 500E- a world beater literally.
We, on these forums, seem obsessed with performance- I am no different. There are not any forums for old guys who want to just tool around in comfort in, say, a nice '64 220S.
Well that is just a thought...
