All we need to know is where is the transmission filler plug on a 40 Dodge one and a half ton duelly flatdeck. I can't see pulling the floor and trans top just to service the lube. Fords all had a square plug on the side and the filler pipe just pumped in lube until it came out the hole. I am down undr for the next month but I will check back here from time to time. Thanks for any help. She's grinding awful bad.
