'95 PREVIA TRANNY OIL PIPE

[kiowa]

Are there two oil pipes in my automatic transmission or is there just one. I see that every book I have shows that that there are two. The factory manual and the Toyota dealer also show two, but when I went to get an oil pipe from my parts van, I only found one in its tranny. That van ran without any transmission problems before I decided to park it and use it for parts. Has anyone done any work on them and was there one or two of these pipes. They are about 3-4 inches long and have 90 degree ends that connect two ports. HELP!!
