What I use are Danco O rings from Home Depot plumbing section. Oil, tranny, primary drain plugs are 9/16" ODx3/8" IDx3/32" Danco #8 with the blue label. Transmission o ring is the Danco #13. 7/8"ODx11/16"IDx3/32" Also has blue label. Drew

Dr V, you gave #8 for oil, tranny, and primary drain plugs and then also state #13 for transmission. I am confused???????? 3 plugs? 4 plugs? I bought Fastenal o rings and use same size on all 3 plugs.

Dr.V: thanks; they worked perfectly! I almost did'nt get the 13 but thankfully I did, because I managed to break the tranny dipstick o-ring. Thanks again.
