So yesterday my buddies and I went to a concert a little over an hour away. It was Anthrax, Black Label Society and Hatebreed. We took the wagon just for the cool factor plus I picked up a stove for one of my apartments. Anyway it was another hot and humid day. Wagon was fine and we got home after midnight. Lo and behold there is a puddle of transmission fluid under it. I jack it up and look, it's pouring out of the tranny plate, thus it has to be a blown seal. I think this may be the time to upgrade from the 273/904 to a more modern 318/360 and auto. I can find them in my area no problem with that. From what I understand in the past there are some differences with the 65 Bs. Can I get a list of do's and don't's? What needs to be kept, modified etc? I already know that I'm going to install an aftermarket floor shift and change out the driveshaft. Your help is always appretiated.
