68 Valiant first runs

How do you check your trans fluid? Do you check it in gear or in neutral? Should be at operating temp for a while. Warm it up, run through the gears, check it. Then, take it for a quick ride and re-check. You will usually need to add a quart or more. You can be off a lot - like a quart or two if you don't check it at the right temp. If you put the full amount in, warm it up, check it then forget it you will be over. You probably know that already though.

On the oil - do you have the correct dipstick? 9 quarts sounds like too much. Car sounds like it runs OK but like said above, you could pick up with less oil.
