Re: 4L60E rebuild, no 3rd gear
I am very new at this and in fact, this is my first automatic rebuild. So, what I have done is based on my reading and online videos.
When I pressure check, I put my air gun nozzle in that hole in the picture, I block the hole on the drum's body with my finger and based on what I have researched, the 3-4 clutch should hold the pressure with no leak, but I get the leak from the drum and when I hold my hand over the input shaft inside the drum, I feel the air.
I am sorry but I don't know the exact science (the flow) of the system. So, I need a new drum or is it possible that I am installing something the wrong way?! It seems very straight forward process in the videos!
