I changed my transmission fluid but I can only get 4 quarts of fluid to go in the fill hole. I know it needs a lot more because more came out when I drained it. Also it slips and shifts hard now when I test it. I have tried three different days to put more fluid in it while in park idling . It just keeps spitting it out. I even tried putting the hose deeper in the pan but it still spit it out. What a head ache! Im not sure what to do. Does anyone know another way to put more fluid in it? Thanks for any help someone can give me. Ray.
