The T.C. in my stock 47re is on it's way out and I want to upgrade. I don't plan on seeing more than 300hp out of my truck and I tow 6500lb. pretty regular. I know all about ATS and Suncoast converters but I don't have that kind of money right now. Is there an affordable T.C. out there that will do good for my app.? Is a large single disc worth considering or is dual disk the way to go? I'd like to keep it under $600. Any suggestions? I would also consider a good used.
