We have two twin disc 5050 transmissions, checked the transmission oil today while running in neutral and had been warmed up, the starboard transmission showed nothing on the dipstick, the Port was showing almost to the top of the dip stick. Drained all of the oil from each transmission and got one quart from the starboard transmission, which had no dipstick reading, and 1.25 quarts from the port transmission that was reading high. My label says the oil capacity of each transmission is 0.54 gallons. Filled each transmission with 30 weight TO-4 oil exactly 0.5 gallons in each. Ran the engines, then checked transmission oil levels with the engines running in neutral. Now the Starboard engine which had shown no oil on the dipstick reads perfect, just under full, the port engine which had read almost to the top of the dipstick does so again. Both transmissions operate normally, no balky shifts, or abnormal noise. Any ideas why the port transmission continues to show a high oil level on the dipstick
Checked with engines off, oil levels exactly the same on each side just a little above full
