2016 F53 26K lbs 5 speed trans. overflow or what?
Today while crawling around under my rig I noticed oily residue on top of the transmission. Nothing too significant, but probably about 1/4 cup was there spread over the top of the transmission.
It was not fresh and had obviously been there for quite while. I assumed it was transmission fluid as there was no evidence of any leakage from around the engine. It appeared to emanate from a small rubber like 1/4 inch pipe- about 2 1/2 inches tall- that was atop the transmission with some sort of cap on the device . I noticed no seals in the vicinity of this area on top of the transmission-- only the pipe like structure at the top. It was evident that nothing recently had been deposited at this site.
I then checked the transmission fluid level. It was at the bottom of the safe zone after running the temp up to operating levels and putting the rig in gear. I added about 2 cups and raised the level into the safe zone on the dipstick.
Any ideas what this small vertical pipe that sticks up is and why a deposit of what I suspect is transmission fluid from some sort of overflow device? Is this abnormal? I have about 27,000 miles on the chassis.
