Hi everyone,
I have 08 F250 5.4L with 5r11w transmission. After chasing the leak for a while, I found out my truck was leaking on the top of the transmission. I reduced some fluid and the leak stopped, however, the level look low now. After the truck has been running for about 40 minutes, the level barely touch top of the stick (below the c range) measured while the engine was still running. Does anyone experience this symptom?
Thanx

 

You need to determine where it is leaking from. I would not leave the fluid level low.
