I need to order many of your parts for a TH 400 & 4L60E builds I have coming up. I'm a independent small shop, I do not wish to place my order through another shop, rather I would much appreciate if I could order these parts directly from Sonnax. I don't understand WHY you don't have a retail dept. to order your parts online??? Thanks.
