Inspection of a 904 torqueflite
From what I saw.....the bands and clutches weren’t worn bad
The selective washer was worn....the thrust washers were worn
But the stuff in the magnet could have been normal and that might have made the fluid black
Whoever owned that van.....didn’t care about it whatsoever. They were NOT the type to change break in fluid and they were probably on stronger drugs than your taking about
ON this transmission and the 904....I’ll do the bushings.
If I didn’t want to..
I would replace 3 of them. Direct, pump bushing and output shaft. The others I would leave alone.....
