I’m finally now finishing both of these up.
All the clearances were checked and everything torqued and the clutch packs were air checked.
The bands were adjusted. The 904 is back together and Now that it’s done. I have a couple of comments
It feels tight on the input shaft. Of course that’s relative. It had trans goo paste instead of fluid with makes for a lot more resistance. Nothing was put in dry. The shaft turns fine. I have to use a short pair of channel locks to turn it. I can’t by hand very well. Output shaft is the same hard to turn by hand.
So here’s how I adjusted the bands. At first I torqued down the reverse band to 72” pounds and backed off 3 1/2. This kept the reverse locked down and wouldn’t turn at all. I turned back out another half and it was free but seemed to ride a little tight. This might have even been correct
When I got to the front band. It had a square head on it.
So.....what I ended up doing, was to back both the reverse band and the kickdown band back out to where they were both loose.
I tightened the reverse band down to lock it. Then slowly backed it out where it would barely turn freely and smoothly. Then backed it out 1/2 turn....it would turn faster with less resistance.
Once the reverse band was set. I went to the kickdown band and did the same thing for that one. Rotated the transmission the other way. Locked the kickdown to full lock and slowly backed out until it would barely Turn. Then went another 1/2 turn out for that one as well. Hopefully these are right......I know they are at least not too tight.
The 999 is still mostly apart but will be finished today. I guess I’ll adjust those the same way.
