Question about clutch bleeding
Hi there! I got a 03 Ranger 4.0. Im dealing with the symptoms of air in my clutch lines. When i try to move my truck, she doesn't want to go in to first gear from a stop. I went ahead and bleed the clutch somewhat, tried a few methods i've read online such as using a syringe to push fluid through the clutch cylinders with the bleeding screw open a bit.
After I tried bleeding the clutch, the truck was shifting perfectly! I was very happy! in less then 5 minutes the clutch was perfect. Anywho, I took the truck out for a drive that day and later on it started acting up again as if more air got caught in the lines. My question is, could there be a reason why I am getting more air back in? As well what else could have happened after I've bled the clutch to make it stop working as well shortly after.
I know the truck has a new reservoir on it, new house down to the master cylinder and a new master cylinder installed by the previous owner. So could it be sucking air in from the slave end?
