I am thinking about changing some pieces of my transmission that broke into pieces inside the transmission. Are there any chances that the hydraulic lines are blocked by these pieces, or do they have their own fluid? The pieces that broke were the planet gears, and planet carriers. I am also going to change the friction band and some clutches. It is a transmission from a 1999 nissan quest.
In automatic transmissions, is the oil filtered before entering the hydraulic lines?
Most modern automatics have a filter or oilscreen located inside the the transmission, there are some applications with external or supplemental filters. In almost all cases the oil is screened at start up out of the trans oil pan, the oil pump draws it thru the screen and into the system components. It is entirely possible for debris to be in the hoses,coolers, and lines. You may want to blow out these lines with low pressure air before reassembly. if you detect a restriction in the plumbing which you cannot remove with air pressue, you will need to remove and replace them, it is unlikely a large piece in lodged very far from the entrance to the pipe. good luck
In automatic transmissions, is the oil filtered before entering the hydraulic lines?
you need to have the oil changed and the filter replaced, the filter is there to trap those shaving %26amp; crunchies, a magnetic drain plug works well to keep metal shavings from entering into your oil flow, of course the oil is filtered before entering the lines. once the pan is dropped all crunchies can be removed, PS most shop charge 75-90$ to do oil%26amp;filter change for transmissions
