I have a RTO 14613 transmission. It is leaking air from the bottom of this valve. What is the valve called? Easiest way to fix or replace it.
Remove the brass plug on the second picture. Take the valve out and replace it with a new one. Add some lube when reinstalling it. Don’t rip the o rings.
No, you have to remove the plug. And might need some needle nose pliers to remove the valve. O rings are probably shot. That’s why it’s leaking air.
