As the title says, i want to fix some small oil leaks i found in my Getrag 2.3-16 transmission.
I have also a few questions for the transmission gurus in the forum.
First of all, trans wass filled with gear oil instead of ATF, i plan to fill it with dexron III, but if leaks with gear oil, with ATF will be a fountain, then i have to fix the leaks first.
I also discovered a few things:

1- There's free play in the 3 gear levers, so i plan on doing some bushing out of bearing quality brass, as instructed in other sites. The question is: Will they still retain oil without the rubber? They say to use a drop of Loctite, but wich one is a mistery.Won't it stick the lever?

2- There's no pilot bearing. Is'nt supossed to have a pilot bearing somewhere? There's a slot in the flywheel, but no bearing. If needed: What is the measure of the bearing so i can install one?

3- Stupid noobish question: When removed the flywheel found no spacer, but when purchased the car found one in the glovebox, i recall my automatic to have 2 spacers, one between crank and flex plate and the other in the bolts side. So the manual dont need one (and the glovebox one was there just by chance)? I guess not, but someone plz confirm.

4- The vent hole has nothing to cover it. There should go a hose or a vent cap?

Thats all, any help is welcome!!

Was able to remove the nut...with a chisel. Will find out measure with the sample.
Answering my own question, yes it needs a pilot bearing, worked well without it until my clutch became slippery, dont know if related. Found the measures to be (hopefully accurate):

15mm inside dia
35mm outside dia
11mm height

Fits other models as well.

Still to find out if i need a spacer or something to prevent it to go to the bottom when installing the gearbox.

Removed the seals as well, going to buy/fabricate them tomorrow. The brass ones supposedly improves the shifting.

Does amyone know how to dismantle the rear housing of Getrag 717.404? It separates just one millimeter from the main housing, don't want to force it or break something.

here in the states getrags are along the lines of gold...as no one works on them much and everyone wants them for their cars. you may have to check with a mercedes specialist in transmissions. as far as i am aware of they don't come apart easily as they are heat treated when they are assembled

I have a question, first you say there is gear oil not atf, but then you talk about things found on manual trannys. Is this a manual or automatic transmission?

If manual you will want to refill with gear oil.
If auto tranny I would think that if driven with gear oil will probably need to be rebuilt.

Unless Mercedes did something really different here.

Yeah, german engineering is way beyond my winsdom, they used ATF in their manual transmissions, thats their way to make things different. But mine was filled with gear oil, and thats not good i believe.

You are right, those things dont want to come apart easily, i'll just let it be.
The problem is that now i need to reseal the trans with loctite 573 trough a 1mm window.
I also found that the bearing for the rearmost lever were missing, that why it had some free play, nothing hard to replace in situ.
Oh, and i will make a how to on how to replace the seals, it's very easy and no need to lower the trans for the lever ones.
