In the trash pile of over-engineered automobiles people suffer with today, your effort is quite a treasure.
Here's an old page on MB idi injector cleaning , looks like there are some tricks they had back in that day

I guess I hadn't thought of trying to clean it.
I haven't had much luck with that before.
But they are really dirty.
Maybe I'll give that a try on the problem one
before trying a nozzle swap.

I'm still looking for a block heater o-ring.
The harbor freight looked like the one all the parts stores had but none of those fit.
I need something skinny.
maybe 3/16".

I'm not familiar with the block heaters, but this o-ring kit has come in handy a few times where the HF ones don't.

I've read that standard o-rings can be cut to size and superglued. This is actually done in some fields of work. I tried it on an old irrigation valve and it worked.
Glad I did it because later I found out the valve needed replacing anyway, so not much effort was wasted on sourcing that odd size for the test.

Thanks, a 2.5mm o-ring might be thin enough.
I'll have to do some more measuring.
What kind of trany fluid do you suggest?
I want GL4 not 5.
I've heard good things about synchromesh.
I used to have a 5 gallon bucket of Delo that was GL4, with boron.

Since I've never played with any high HP setups, Pennzoil syncromesh is what I use.
It's probably not as heavy duty as the red, purple, etc. gear oils but it protects the metal properly, cleans out the gearbox, and shifts great.
PennzSyncromesh is a bit thin - that's why it cleans and shifts so well, probably great for cold weather, too.

One thing I like about the PS is I'll buy several online from AA with a code (ex. RMN25), do local store pickup and have plenty.

These old 020's are generally pretty dirty inside (as brokevw shows) and imo can use several early oil changes to clean them up.
I drove my S1 underwater in Mexico about a year ago and when I got back it needed a couple of quick changes to get the sludge out.

If the gearbox is clean and I want something a bit thicker and HD, I'd go to Valvoline mtf

I've read a lot of comments about popular gear oils people use not being formulated exactly for our transmissions,
but the pennzoil and valvoline syncromesh's formulas seem be spot on for the regular 020's.

Great, that's kind of the way I was heading.
It wasn't too dirty.
The fluid was dark but not real smelly.
And there was a little sludge and shine in the bottom of the trany and what I drained.
But I've seen alot worse.

Looks like it needs a new CV boot on the passenger side too.
