I looked up the capacity on line for a SM420 and found that the transmission is said to hold 5.5 quarts. I drained the fluid and collected 3 quarts. Put in the drain plug and took out the fill plug (on the side), removed the shift lever and refilled. 3 quarts in and I have a drip out of the side fill plug hole. Is the capacity 3 quarts or shoul I put in the plug and add another 2.5 quarts?
What would you do?

Well I guess The capacity is stated as 5.5 pints not quarts. That calculated to 2.75 quarts. I will call 3 quarts good and save the other 3 quarts that I bought.
