Lots of good advice here. without knowing how the loader is plumbed it is anyone's guess of where exactly to look for the problem. 3/4 way valve, power through, remotes, many ways to do it. Pictures would help us.
I don't flush with diesel, it can be as hard to get out as water, it is nearly as expensive as oil. a 990 only holds 5-6 gallons of oil. a bucket of cheap hy-tran is $35 at TSC. 15-40 motor oil is best if you have a cheap source.
The valves in the selectamatic unit can stick so badly that the wooden stick trick will not work. I just did one on a 1494 that took a big hammer and a punch(while out on a workbench). There are 9 valves in the box most of which can stick in their bores, each will give different symptoms. Some polishing with 1500 paper and a good cleaning of debris is probably the worst case scenario.
It is a big job to pull the selectamatic valve box. Pull sensing unit, drop lower links, rockshaft, quadrant, parking brake handle, and lots of little fiddly bits. Cabbed tractors are much worse.
