SL300-24 Auto box issue

[BlackC55]

I suspect the mecanism inside the selector module is the problem. Quite often drinks, dirt etc get caught up inside and jam it. Also lack of use may cause it.

If it was my car I would probably just live with it as selecting 2nd is not always necessary.

I am looking at the 722.5 shift lever and I can see that there is only the direct coupling, if it goes into P then there is nothing much in the gearshift lever that can stop it and any fault must be in the box.

So as Olly I would leave it

Does that make sense given Olly's post? There is quite clearly a lockout mechanism.

The gear shift only has a rod linked to the box input shaft and all of the detents are on the shaft,in the box, this means unless something is jamming in the quadrant the fault must be inside the box

I think you're looking at the wrong version, Malcolm. The gearshift has a lot more inside than just a linkage.

No the correct 722.5 is very simple take a look, its just one bar with one adjustment, and that is for fore and aft only, and nothing else

What 722.5** are you looking at?

What 722.5** are you looking at?

The one fitted to this car, and a 124 at that,its the same gate as in the 129. I have turned it off now, but I can open it again this evening

OK - the W124 shift is different to the R129 (brake and steering lock cable lockout). For instance the lockout lever on the R129 is part A1292600937 - not found on the W124.

The gearboxes have different codes - 722.500, 722.507 etc The W124 has differing ratios as well.

Would be easier with the VIN to know for sure.

Nothing is different its the same document for 124,129 and 140 it covers the 722.5 and the 722.3 in the 461 and 463 I could not care lees about the ratio's

That document is irrelevant - it's for a 1994 car and is specifically for adjusting the linkage and nothing to do with the internals.

I have never ever here said anything else, and my answer in the beginning was to those who said the quadrant could be faulty.

Everyone of my post has referred to the shift lever and parts and nowhere have I mentioned, discussed, claimed, looked,thought, about the internals, as it would be a waste of time and beyond the OP to check.

Amen

Maybe the rod is bent?

I have come to a stop on it Olly

Malcolm you seem to have got the wrong end of the stick . The internals are the gearshift internals - you've been saying for the last 4 posts that they're irrelevant as they have no locking mechanism when clearly they do!

What has a shift linkage adjustment doc got to do with any of this?

In my opinion it does "feel" like a selector issue rather than an internal issue. When the selector is pushed from D to 4 you can fell the detent which is more pronounced than say selecting D from N or 3 from 4. When trying to select 2 from 3 it feels like the selector is hitting a stop rather than the other end of the rod preventing selection but I was unaware of the lockout mechanisms involve.

In any case, its not really stopping me using / enjoying the car and it only a minor niggle, certainly not worth any argument! )

Thanks for your help all round and any further comments are welcome!

Interesting that you never get the wrong end of the stick, I answered to Ollies post 21 no more and no less.
Other people have had 124'and 129's and worked on them

Your comments on this device appreciated then Malcolm:

Looking at the VIN the gearbox is a 722.500 so the above diagram is correct.

I would suggest it is a cheap fix if you can find the reason behind it as like you say - the gearbox behaves normally in all other operation. You could always print off this info and show it to a local indie for his opinion or pay a vist to Kent Steve who is a MB gearbox specialist.
