WRONG - I finally got around to reading through a good bit of this thread last night and I have not seen any bs. I think it is very clear and well put together/documented. I've actually subscribed to the thread to to use it for future reference.

You have/are doing a GREAT job with it Army and I want to extend a big THANK YOU for putting it together.

The reason you don't see alot of input is because there are very few people on this board that have been this deep in one of these MB transmissions. I am not in that group yet but do see a need for the service. I had a spare one time that I was intending to tear apart and learn all about it but ended up trading it towards a rebuild.

Army,
this DIY is a work of art. Leaves the trans manual for dead !!!!

a very good piece - thats why I love PP so much, far better than the cryptic factory procedure.

where do you hook up a pressure tester on these transmissions?

There are two on the front in this picture that I posted on the first page



I think these are for measuring the working pressure and the front pump pressure. I'll check for sure...

EDIT:-

I don't know where I saw the information regarding these two ports on the front of the transmission. I swear I saw it somewhere and I'm not just dreaming it up. If I stumble upon the information I'll post back.

Does anyone know what they are for? Could it be front pump and torque converter pressures? (I'm guessing it isn't working pressure as that can be measured from the rear - see next post)

is there a key to adjust the shifting to tighter on the w115 240d trans?
Other models have that provision.
thanks.

and I hope to be adding to it. I have the old transmission out of my '81 240D that I pulled a few years ago. I am too curious. I MUST get inside and find out what went wrong with it. On a trip to town one day, it just up and stopped moving the car. I want to build a tear-down bench for it- stainless steel, slightly (very slightly) sloping, with a drain for fluids to go into a large bucket, and a screen for BB's, springs, screws......and lots of LIGHT!

Sounds great - the more information posted on the forum the better our common knowledge becomes - my guess would be the splined shafts on the front planet assembly or a front pump issue. Either way strip it down! Good luck.

Do you mean you are looking for a special tool as in "a key" or are you looking for a trick / method to adjust the shifting behaviour.

In either case you need to post up the transmission type - what's it going to be a 722.108? - and whether it has a vacuum modulator as well as a throttle linkage - or both or not - or just an adjustment screw for the modulator pressure - or not!

The 722.118 - the subject of this thread - is very specific to particular W123 300Ds from about 1980(ish). Furthermore I've only covered the mechanical pulling it to bits and putting it back together - as I said in the beginning of the thread adjusting the bloody things is a whole different ball game. That's a whole different thread.

To get an idea of what you may need to do have a look at this thread on the wiki

I have been able to firm up the shift, but wanna to raise the RPM wen shifting, as shift too early cause the tranny to flare up.
Thanks

What is the difference between the 722.118 and the 722.117? The one I will be tearing down form my '81 240D is the .117 version. Maybe the valve body. We will find out!!!
