John Deere 4840 transmission pump prime problem
| Ryan Weiss | My 4840 transmission pump does not want to prime. At start up, I have to bring engine to full rpm to get oil to front to allow it to move ect. Sometimes, it does not prime, wait a day come back and try agian it will take off. I changed filters, cleaned sump screen still has problems priming. Once it does prime, everything works as it should, and I have check flow from pump and pressures, everything checks ok. Thanks for the help
