C900 Tranny Rebuild
I'm starting this section assuming you have already pulled the engine and tranny out of the car.
You can perform a tranny rebuild with the engine attached to the tranny, but it is much harder. I would recommend you pull them apart just to make life easier!
The first thing to do is to clean up the transmission case while all of the covers are still on.
The best way to do this is to use some engine cleaner spray and then scrub and power spray the housing.
The cleaner you make it now, the better off you are later!
Drain the tranny of all the oil and start removing the covers.
For the later year trannys, there is no drain plug so your only way to drain it is to remove the covers.
All of the bolt lengths are different for each cover so be sure to keep all of them together once you remove a cover.
I used separate coffee cans for each cover.
These covers are the sneak peak of what is to come!
The differential is where I like to start when tearing down a tranny.
In order to get the differential out of the housing, you have to remove the inner CV joint cups.
After pulling out both of these cups the differential will be free in the housing.
Be sure to keep the small spacers together with each cup and don't mix them up! These are very carefully measured and locate the differential correctly onto the pinion gear.
If you keep the spacers and use the same pinion/differential you will not need the special tool to
measure this. It will not change after the rebuild.
The next thing to do is to remove the differential. To do this you have to twist and pull it a certain way. I cannot explain it, but it is a little tricky.
The housing will look something like this when you're done.
