Hello all maybe a silly question...i had a leak in the steering control return line in the cab and replaced it. Lost a couple quarts maybe a little less. I must have refilled the hydraulic oil with the tractor idling because it now shows overfull on the stick by a half inch. With engine idling it is exactly to the full mark.

Does the excess need to be drained or is the reservoir big enough that the extra oil is ok? Any ssues with the overfill?

One more thing, I get a momentary "flash" of the transmission warning light when I put the quad range selector in park. Just a blink. Doesnt come on otherwise. Whats causing that?

Thanks all.
 

Trans case holds 13 gallons. I think you'll be fine at 1/2'' over full. Flash of trans pressure light is caused by temporary lowering of trans pump pressure.
