slk230 auto wont change up

[excat]

When my 1999 car has been left for more than about 12 hours my auto box won't change up from 1st. Also when I drove off, the 'clutch' seems to slip and then there is a clonk as it seems to engage into gear. If I drive it for about 5 mins at about 25mph and 3000 revs it will suddenly work, although it still is temperamental

Garage has changed the electronic sensor module (£380) but it has made no difference.
Any ideas. I know nothing about auto boxes, but could it be a slow hydraulic leak or something like that.

Obviously it is going back into the garage but I haven't got a lot of faith in them fixing this.

Sluggish auto box

Had a similar problem, when left for a while the car was not keen on moving but once warm worked OK, I had the automatic transmission fluid and filter changed and it has run perfectly ever since.So i intend to have the oil and filter changed every second service Cost approx £120 at my local dealership

Under the fault condition 1st and 2nd hard to shift when cold

In the car with number 716.600 to 716639 reduce oil in box by 1.2 liter
in 716.640 to 716.679 reduce !.5

in the post above are you advocating that people drain all the oil out of their gearboxes?

Just to clarify, I've added a copy of another post of yours relating to this issue. You will see quite clearly that the correct amount of oil to remove is 300ml not 1.2 or 1.5 litres!!!!

On cars number model 163,170,202,203,208 and 210 there was are revision dated 01 02 01.

With gearbox number from 716.6 the filling capacity changed.
transmision 716.60/62 filling capacity changed from 1.5 to 1.2 liters
transmision 716.64/66 filling capacity changed from 1.8 to 1.5

The reason for the change makes the car change from 1st to 2nd when cold.

I'd also like to point out that this mod applies to manual gearboxes not autos so it's not really relevent here

copyright infringing attachment or not the information you posted originally was incorrect and the quote I included was your verbatim copy of the WIS info - I did this in order to make sure that I wasn't accused of misleading anyone.

I also not that you have still not acknowledged that this refers to manual boxes not autos. Perhaps another quote with more amendments would be a good idea?

Sinse when can a 716 gearbox be manual, I do not answer post on manual gearboxes as I know nothing much about MB manuals

I will ask the admin to stop you posting silly remarks

Malcolm

since the 722 box was the auto box fitted to most of the models you listed

since an MB auto box has a much higher capacity than 1.8 ltrs (usually just over 6 litres) which just by coincidence is the exact amount of fluid required to fill the manual box.

You ask me to stop making "silly posts" well I will if you do

My reason for answering this thread was that the information was accurate
and can be verified and carried out easily by any gear box center.
This modification has been around for five years and has only come to light because of the cold spell.

Andy K has joined this thread for one reason only ,that is to to dis credit me.
we have both had warnings of this type of thing in these threads, but it goes on.
His last remark is totally wrong.
On this thread the mod was to lower the oil in the sump to 1.2 and 1.5 respective.
Andy is saying that my answer is for a manual gearbox, and that is totally wrong. What Andy K does not understand is that we are not talking about an oil change,just lowering the level. The figures that I gave are correct.
Most of the oil is in the torque converter and most boxes do not have a drain plug, so anyone thinking of chainging the oil, you cant. this is also the reason that the dipsticks were discontinued.

Well I've seen nothing but common sense from Television's posts, so I know who I'd trust.

 

[andy_k]

Malcolm, much as I feel getting into an argument with you is both futile and against the forum rules, once again, as well as reporting them to the forum admin I feel bound to point out the innacuracies in your posts should some poor unfortunate come across the inacurate information.

no matter how many times you deny it you told us that a fix for a harsh change between first and second was to drain either 1.2 or 1.5 litres of fluid from the box. This is obviously incorrect as you have since posted that the boxes only hold either 1.5 litres or 1.8 litres in total. Once again, I ask you to justify the instructions you made based on your personal experience not on something you have copied from a manual you are struggling to understand.

The auto boxes have a much higher capacity than you say (as other members have also indicated) and not all of that oil is stored in the torque convertor. a dry change on a 5 speed 722 box will take just short of 7.5 litres which you have to accept is a huge difference from the 1.8 litres you suggest. Just because it says fill the box with ATF doesn't mean it's an auto - all the MB manual boxes are designed to use ATF

As a direct challenge to the information you are posting my next door neighbour owns a W202 with the auto box you say needs 1.8 litres to fill it. He is happy to

a, drain all the fluid and refill it with your recommended amount then drive it until it breaks on the basis that you will pay for all repairs should things go wrong

b. let me post a copy of his latest service receipt where Mercedes Eastbourne changed his auto transmission fluid and charged him for 7.3 litres

either will do - please let me know

Let the mods do as they please, but this is not a personal attack nor is it flaming, it is pointing out to members that not all the information they are offered on these forums is worth reading.

Gentlemen,

This thread is most confusing, but since I have one of the cars that you are arguing about I am most interested, especially since I recently paid for an oil change on the gearbox which apparanty cant be done!

First of all I think (hope) that I am right in saying that a 1999 230SLK has to be auto, I dont think manual gearboxes were offered until the facelift model came along. Regardless of this the original post is clearly speaking of an auto gearbox problem.

Next is the problem of getting the oil out if no drain exists, and even if it does are we really saying that the correct method is to drain off a measured volume of oil, what if the level wasnt correct in the first place?

Surely what MB should (would) do is issue a new dipstick that would be marked to the new level.

Finally the post is confusing but appears to say that MB now recommend around 20% - 25% less oil is to be in the gearbox. This is unprecedented in my 30 years of interets in the motor industry. Could you confirm the details of the relevant MB technical bullitin so that I can quote it to my dealer in the morning when I ask if they have complied with it.

Mark.

You will never find one posting from me saying how much oil a gearbox holds.

hmmmmmmmmm so what's that then?????????????????????????????????

 

[television]

That's the amount that can be teken out without dismantling the whole gear box and stripping it down.

Happy

[andy_k]

no, the amount you can take out under the mod you quoted is 300ml, the difference between 1.2 litres and 1.5 litres. On your third attempt at posting this mod you at least got that bit right

The "filling capacity" is just what it says, how much ATF you put in the box to fill it - hence the use of the words "filling" and "capacity". I don't think they could make it any clearer than that could they?

Phew, didnt know I would need my crash helmet other than for riding my bike. My mate has a 6 speed manual SLK and had great problems changing from 1st to 2nd when it was cold. He had a look on benzworld and found this

http://www.benzworld.org/forums/forums/thread-view.asp?tid=1238827

Cant see how it will help the posters automatic gearbox though.

 

[andy_k]

thanks for that link Benzboy although it certainly helps clear up a few points I'd keep the crash helmet handy for a while yet

Sinse when can a 716 gearbox be manual, I do not answer post on manual gearboxes as I know nothing much about MB manuals

so now it turns out that the 716 is a 6 speed manual (as I have been saying all along) will you be offering a full retraction of all your comments and an apology to those you have either been rude to or misled?


Andy

PS I'm not holding my breath

Gentlemen,

I am rather pleased that I read the authoritive thread provided by Benzboy before making a complete fool of myself at the local dealership.

Television:

Could I ask you to confirm (without becoming part of the argument you seem to be having with Andy) that the info you provided about reducing oil levels is actually to do with manual gearboxes only and nothing to do with the fault on this thread?

Thanks in advance,


Mark.
